The current and voltage polarities depend on the model number: -P units: 0 to +50 V amplitude (0 to +50 Amps) -N units: 0 to -50 V amplitude (0 to -50 Amps) -PN units: 0 to ±50 V amplitude (0 to ±50 Amps) The pulse repetition frequency can vary from 1 Hz to 20 kHz, and pulse widths can vary from 40 ns to 1 us. The maximum duty cycle is 0.4%, and the maximum ave rage output power is 10 Watts. The Model AVOZ-A2-B pulse generator is a voltage pulser. The current am plitude is determined by Ohm’s Law. That is, the current is the output voltage div ided by the load resistance. The load resistance should be approximately 1Ω to attain a peak current of 50 A. The loads can be connected to the pulse generator using the convenient AV-CLZ1-60 transmission line cable assembly, which has a 1Ω characteristic impedan ce (Z0), and is terminated with a DB-37 male connector. A sample connectorized test loa d is provided. The AVOZ-A2-B can be controlled from the front panel, or via a computer connected to the IEEE 488.2-compliant GPIB port, or the RS-232 serial port. This instrument is intended for use in research, development, test and calibration laboratories by qualified personnel. __________________________________________________________________ 6 SPECIFICATIONS Model1: AVOZ-A2-B Amplitude2,3: current: 0 to 50A voltage: 0 to 50V Minimum load impedance4: 1 Ω (required to limit current) Pulse width (FWHM): 40 ns - 1 us Rise time (20%-80%): ≤ 30 ns Fall time (80%-20%): ≤ 10 ns Maximum PRF: 20 kHz Duty cycle: (max) 0.4% Output impedance: ≤ 0.05 Ω Average output power: 10 W max.

P OWER Switch . This is the main power switch. When turning the instrum ent on, there may be a delay of several seconds before the instrument appears t o respond. 2. O VERLOAD Indicator . When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an int ernal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low imped ance), the protective circuit will disable the output of the instrument and turn t he indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 s econds after which the instrument will attempt to re-enable the output (i.e. light g reen) for about 1 second. If the overload condition persists, the output will be disabl ed again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation. This overload indicator may flash yellow briefly at start-up. This is n ot a cause for concern. 3. S YNC OUT . This connector supplies a SYNC output that can be used to t rigger other equipment, particularly oscilloscopes. This signal leads (or lags ) the main output by a duration set by the "DELAY" controls and has an approximate amplitude of +3 Volts to RL > 50Ω with a pulse width of approximately 1 00 ns. 4. L IQUID CRYSTAL DISPLAY (LCD) . This LCD is used in conjunction with th e keypad to change the instrument settings. Normally, the main menu is di splayed, which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenu s in detail. __________________________________________________________________ 15 5. K EYPAD . Control Name Function MOVE This moves the arrow pointer on the display. CHANGE This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. ×10 If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten. ÷10 If one of the adjustable numeric parameters is displayed, this decreases the setting by a factor of ten. +/- If one of the adjustable numeric parameters is displayed, and this parameter can be both positive or negative, this changes the sign of the parameter. EXTRA FINE This changes the step size of the ADJUST knob. In the extra- fine mode, the step size is twenty times finer than in the normal mode. This button switches between the two step sizes. ADJUST This large knob adjusts the value of any displayed numeric adjustable values, such as frequency, pulse width, etc. The adjust step size is set by the "EXTRA FINE" button. When the main menu is displayed, this knob can be used to move the arrow pointer. __________________________________________________________________ 16 REAR PANEL CONTROLS 4 8 11 1 3 5 GRN=LNK GATE YEL=ACT LAN TRIG RS-232 OUT P OUT N AMP GPIB 9 6 7 10 2 1. A C POWER INPUT . An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. O ne end of the detachable power cord that is supplied with the instrument plugs in to this socket. 2. A C FUSE DRAWER . The two fuses that protect the AC input are located i n this drawer. Please see the “FUSES” section of this manual for more informat ion. 3. D C FUSES . These two fuses protect the internal DC power supplies. Ple ase see the “FUSES” sections of this manual for more information. 4. G ATE . This TTL-level (0 and +5V) logic input can be used to gate the triggering of the instrument. This input can be either active high or active low, dep ending on the front panel settings or programming commands. (The instrument triggers normally when this input is unconnected). When set to active high mode, this inp ut is pulled- down to ground by a 1 kΩ resistor. When set to active low mode, this in put is pulled- up to +5V by a 1 kΩ resistor. 5. T RIG . This TTL-level (0 and +5V) logic input can be used to trigger t he instrument, if the instrument is set to triggering externally. The instrument triggers on the rising edge of this input. The input impedance of this input is 1 kΩ. (Dependi ng on the length of cable attached to this input, and the source driving it, it m ay be desirable to add a coaxial 50 Ohm terminator to this input to provide a proper trans mission line termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thr u 50 Ohm terminator is suggested for this purpose.) When triggering externally, the instrument can be set such that the out put pulse width tracks the pulse width on this input, or the output pulse width c an be set independently. __________________________________________________________________ 17 6. G PIB Connector . A standard GPIB cable can be attached to this connect or to allow the instrument to be computer-controlled. See the “Programming Manual f or -B Instruments” for more details on GPIB control. 7. R S-232 Connector. A standard serial cable with a 25-pin male connecto r can be attached to this connector to allow the instrument to be computer-contr olled. See the “Programming Manual for -B Instruments” for more details on RS-232 cont rol. 8. L AN Connector and Indicator . (Optional feature. Present on -TNT units only.) The - TNT option "Internet-enables" Avtech pulse generators by adding this st andard Ethernet port to the rear panel, in addition to the IEEE-488.2 GPIB and RS-232 ports normally found on "-B" units. Commands may be sent using the standard T elnet protocol, or using a web browser. The SCPI-compliant command set is the same as that used for GPIB and RS-232 control. The -TNT option uses the Dynamic Host Configuration Protocol (DHCP) to obtain its network address. A DHCP ser ver must be present on the local network for the -TNT option to operate properly. 9. A MP Connector . (Active on units with the -EA option only.) The output amplitude can be set to track the voltage on this input. Zero Volts in corresponds to zero amplitude output, and +10V in corresponds to maximum amplitude out. This mode is activated by selecting "Ext Control" on the front-panel amplitude menu, or with the "source:voltage external" command. 10. O UT P . This is the main positive output, present on “-P” and “-PN” un its. It is only active when the amplitude is set to a positive value. The AV-CLZ1-60 tr ansmission line plugs into this DB-37 female connector. Pins 1-19 (the upper row) are connected to the signal out, and pins 20-37 (the lower row) are connect ed to ground. 11. O UT N . This is the main negative output, present on “-N” and “-PN” un its. It is only active when the amplitude is set to a negative value. The AV-CLZ1-60 tr ansmission line plugs into this DB-37 female connector. Pins 1-19 (the upper row) are connected to the signal out, and pins 20-37 (the lower row) are connect ed to ground. __________________________________________________________________ 18 GENERAL INFORMATION - PULSE GENERATOR TIMING BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an ext ernal TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC. The OUT channel is the signal that is applied to the device under test. Its amplitude and pulse width are variable. The SYNC pulse is a fixed-width TTL-level ref erence pulse used to trigger oscilloscopes or other measurement systems. When the de lay is set to a positive value the SYNC pulse precedes the OUT pulse. In the diagrams below, positive amplitude is assumed. (For “-N” units, the output waveforms are inverted in polarity.) These pulses are illustrated below for a positive delay, and internal t riggering: 100 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Basic Output Pulses for Delay > 0 The order of the output pulses is reversed for negative delays: 100 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY < 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Basic Output Pulses for Delay < 0 When the triggering is set to external mode, a TTL-level pulse on the T RIG input will trigger the pulse generator, as shown below: __________________________________________________________________ 19 > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 100 ns, FIXED SYNC OUT 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT As before, if the delay is negative, the order of the SYNC and OUT puls es is reversed. TRIGGER MODES This instrument has four trigger modes:  Internal Trigger: the instrument controls the trigger frequency, and ge nerates the clock internally.  External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector.  Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton.  Hold Trigger: the instrument is set to not trigger at all. These modes can be selected using the front panel trigger menu, or by u sing the appropriate programming commands. (See the “Programming Manual for -B Instruments” for more details.) GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GA TE connector. The instrument can be set to stop triggering when this input high or lo w, using the front- panel gate menu or the appropriate programming commands. This input can also be set to act synchronously or asynchronously. When set to asynchronous mo de, the GATE will disable the output immediately. Output pulses may be truncate d. When set to __________________________________________________________________ 20 synchronous mode, the output will complete the full pulse width if the output is high, and then stop triggering. No pulses are truncated in this mode. __________________________________________________________________ 21 GENERAL INFORMATION - OPERATING INTO A LOAD AMPLITUDE CONTROL The Model AVOZ-A2-B pulse generator is a voltage pulser. The current am plitude is determined by Ohm’s Law. That is, the current is the output voltage div ided by the load resistance. More specifically: IOUT = (VSETTING – VDIODE) / R, where VSETTING is the set amplitude, VDIODE is the diode voltage, and R is the series resistance (including any series resistance in the diode itself). R is normally 1Ω; it should not be smaller than this. Avtech recommends connecting multiple Ohmite OX or OY-series or RCD RSF2B resistors in parallel to create a high-power, lo w-inductance effective resistance. SELECTING THE SERIES RESISTANCE The best waveforms will be obtained if the amplitude is set between 20% and 100% of the maximum rating (i.e., 10V to 50V), and if the load resistance R is chosen to be between 1.0 and 1.6 Ohms. It should never be less than 1.0 Ω, or the instrument may be damaged. For applications requiring less than the maximum possible current, best results may be obtained if R is approximately 1.6 Ω, because this slight increase in t he load resistance will result in a faster transition times. However, the load resistance should not be increased beyond 1.6 Ω, or the transmission line mismatch between the o utput transmission line (which has a characteristic impedance of Z0 = 1 Ω) an d the load may introduce significant ringing. If the resistance of the device under test (DUT) is significantly highe r than 1.6 Ω, resistance should be added in parallel with the DUT so that the total e quivalent resistance is 1.6 Ω. OUTPUT CONNECTIONS The main output is provided on a rear-panel DB-37 female connector. Pin s 1-19 of this connector (the upper row) are connected to the signal out, and pins 20- 37 (the lower row) are connected to ground. An AV-CLZ1-60 transmission line is supplied with the instrument. One en d plugs into the rear-panel connector. The other end is terminated with a DB-37 male connector. Pins 1-19 of this connector (the upper row) are connected to the signal out, and pins 20-37 (the lower row) are connected to ground. The cable is reversible - either end can be plugged into the rear panel. This cable can be ordered separately, a s model AV- __________________________________________________________________ 22 CLZ1-60. (Lengths longer than 60 cm are also available - see http://www.avtechpulse.com/transmission/av-clz1 for details.) The user may connect a load to the end of the AV-CLZ1-60 transmission l ine using a load that has a DB-37 female connector. To construct your own connector ized load, consider using a Norcomp 172-037-201-001 DB-37 female connector with so lder cup pins. This is readily available from Digi-Key (http://www.digikey.com, stock number 137F-ND). Care must be taken to construct the connectorized test load t o conform to local safety standards. High voltages (up to 50V, approximately) will b e present on the load during normal operation. Pins 1-19 short be connected together to provide the signal output, and pins 20-37 should be connected together to provide t he ground. It may be simpler to modify the supplied test load. The supplied test l oad has this connector pre-installed, and a safety enclosure is provided. This test load is described in the next section. USING THE SUPPLIED TEST LOAD (AV-CTL1) The supplied test load consists of a DB-37 female connector mounted on the lid of a small aluminum box chassis. Inside the chassis, an 8 mm by 50 mm circui t board is sandwiched between the two rows of solder cups on the rear of the conne ctor. Four Ohmite OY-series 3.9 Ohm resistors are connected in parallel between th e two rows of solder cups. This provides a total resistance of 3.9 Ω / 4 ≈ 1.0 Ω. Two unused SMA connectors are provided for making connections through t he chassis wall, if desired. A 5/16" hole, plugged with a screw is also provided. The screw may be removed to provide an access hole to the interior of the chassis. Due to the presence of high voltages on the output (up to 50V, approxim ately), the lid should be installed on the aluminum chassis so that users can not physi cally touch the load. The test load has a maximum power dissipation rating of 5 Watts. Take c are not exceed this! This test load can be ordered separately, as model AV-CTL1. It can also be ordered with no resistors installed, as model AV-CTLX. The basic mechanical connection scheme for the AV-CTL1 is shown below. The -ENC safety enclosure is an optional feature, which is not normally included . __________________________________________________________________ 23 AV-CLZ SERIES TRANSMISSION LINE CABLE ASSEMBLY Pins 20-37 (Ground) Pins 1-19 (Signal Out) Plug the AV-CLZ cable into the lid-mounted DB-37 female connector Aluminum Lid Pins 20-37 (Ground) Measure output here (pins 1-19) If using the optional Install your load here, between the -ENC enclosure, two sides of the 8x50 mm circuit secure the lid to the board.

NOTE: BOTH DIODES ARE SHOWN ORIENTED FOR A POSITIVE OUTPUT. REVERSE BOTH DIODES FOR NEGATIVE OPERATION. The diagram above shows how high-impedance oscilloscope probe can be us ed to observe the waveform. However, since the load impedance is so low (1 Oh m), a 50 Ohm measurement system like that shown in the diagram below can also be used to observe the load waveform. An attenuator should be used to avoid damagi ng the oscilloscope input, since the load voltage can be as high as 50V. (Two SMA connectors are present in the AV-CTL1 test load, and either can be used to connect the 50 Ohm coaxial cables through the chassis wall.)

As explained above, a resistance should be added in series with the diode load, to limit the maximum current. This resistance may also be used to monitor the current through the diode current. If conne cted as shown above, the resistor voltage displayed on the oscilloscope is directly p roportional to the diode current. It is essential the low-inductance resistors be used. Se veral non- inductive, medium power resistors should be used in parallel (for insta nce, four 3.9 Ohm 2W resistors). The Ohmite OY series (www.ohmite.com) or the RCD RSF 2B series (www.rcd-comp.com) are appropriate. It is also recommended that a low-capacitance, high-voltage, ultra-fast Schottky rectifier diode be connected for reverse-bias protection, especially for sensitiv e or costly devices under test. The APT (www.advancedpower.com) APT15S20K is an example of a suitable diode. Note, however, that the capacitance added by the protec tion diode may degrade the output rise time slightly. LENZ’S LAW AND INDUCTIVE VOLTAGE SPIKES This instrument is designed to pulse resistive and diode loads and will exhibit a large output spike when used to drive a load with significant inductance (as predicted by LENZ'S LAW). For this reason the load should be connected to the output using low inductance leads (as short as possible and as heavy a gauge as possible ). The voltage developed across an inductance L (in Henries), when the cur rent is changing at a rate given by dILOAD/dt (in Amps/sec), is: VSPIKE = L × d ILOAD/dt. For this reason, the length of leads used to connect the load to the ci rcuit board should be kept extremely short ( < 0.5 cm). ATTACHING AND DETACHING LOADS To avoid damaging the loads connected to main outputs, the loads should only be connected to or removed from the instrument when the instrument is off. Do not connect loads when the instrument is on and the output amplitude is not zero. This can cause sparking. MEASURING OUTPUT CURRENT Two basic methods can be used to observe the current waveform through t he load. The first is to observe the voltage waveform across the resistance present in the load. If the resistance is non-inductive, the voltage waveform will be directly prop ortional to the current waveform (Ohm's Law). Keeping the parasitic inductance low is c ritical for reliable measurements. If a diode is connected in series with the resis tance, it may be advantageous to ensure the diode is placed before the resistance, so th at one end of the resistance is grounded. This will eliminate the need for differenti al voltage measurements. This method is shown in the "TEST ARRANGEMENT" section ab ove. __________________________________________________________________ 26 Alternatively, a high-speed current probe or current transformer can be used to observe the current waveform. One possible model is the Pearson 2878 current tr ansformer (http://www.pearsonelectronics.com). However, this model might not oper ate at the upper end of the AVOZ-A2-B pulse width range (1 us). It may be necessar y to introduce a significant lead length (i.e., inductance) to pass the conductor thro ugh the transformer. __________________________________________________________________ 27 START-UP CHECK-LIST FOR LOCAL CONTROL 1. Connect the supplied test load (AV-CTL1) to the rear-panel of the m ainframe, using the AV-CLZ1-60 cable. 2. Connect a cable from the SYNC OUT connector to the TRIG input of an oscilloscope. Set the oscilloscope to trigger externally. 3. Connect an oscilloscope probe to the signal side of the resistors i n the test load. It may be necessary to connect the probe using the SMA feed-throughs on the test load enclosure. On the oscilloscope, set the channel A vertical sc ale to 20 V/div, and the horizontal scale to 100 ns/div. (A 50 Ohm measurement sy stem, without a high impedance probe, can also be used if desired. This may b e more mechanically convenient. See the "TEST ARRANGEMENT" section for details .) 4. Turn on the instrument. The main menu will appear on the LCD. 5. To set the instrument to trigger from the internal clock at a PRF o f 1 kHz: a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. b) Press the CHANGE button. The frequency submenu will appear. Rotate the ADJUST knob until the frequency is set at 1 kHz. c) The arrow pointer should be pointing at the “Internal” choice. If i t is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 6. To set the delay to 100 ns: a) Press the MOVE button until the arrow pointer is pointing at the de lay menu item. b) Press the CHANGE button. The delay submenu will appear. Rotate the ADJUST knob until the delay is set at 100 ns. c) Press CHANGE to return to the main menu. 7. To set the OUT pulse width to 500 ns: a) Press the MOVE button until the arrow pointer is pointing at the “P W” menu item. __________________________________________________________________ 28 b) Press the CHANGE button. The pulse width submenu will appear. Rotat e the ADJUST knob until the pulse width is set at 500 ns. c) The arrow pointer should be pointing at the “Normal” choice. If it is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 8. At this point, nothing should appear on the oscilloscope. 9. To enable the output: a) Press the MOVE button until the arrow pointer is pointing at the ou tput menu item. b) Press the CHANGE button. The output submenu will appear. c) Press MOVE until the arrow pointer is pointing at the “ON” choice. d) Press CHANGE to return to the main menu. 10.To change the OUT output amplitude: a) Press the MOVE button until the arrow pointer is pointing at the AM P menu item. b) Press the CHANGE button. The amplitude submenu will appear. Rotate the ADJUST knob until the amplitude is set at 50 V (or -50V for “-N” units) . c) Observe the oscilloscope. You should see 500 ns wide, 50V pulses on the probe connected to the main output. d) Press CHANGE to return to the main menu. 11.Try varying the pulse width, by repeating step (7). As you rotate t he ADJUST knob, the pulse width on the oscilloscope will change. It should agree with the displayed value. 12.This completes the operational check. __________________________________________________________________ 29 CALIBRATION ADJUSTMENTS - SOFTWARE PROCEDURES ADJUSTING AMPLITUDE ACCURACY If it is found that the output amplitude settings (as set by the front- panel controls or programming commands) do not agree exactly with measured values of ampl itude (i.e., by examining the output on an oscilloscope), the amplitude calibration can be updated using software commands. The following procedure is suggested: 1) Connect a 1Ω high-power resistive load to the output. 2) Connect the pulse generator to a computer using the GPIB or RS232 po rts. 3) Turn on the pulse generator, and set the time controls (frequency, d elay, pulse width) to typical values. 4) Turn on the outputs. 5) Set the output amplitude to 50V. 6) Observe the voltage across the load. (For example, suppose it is 52V ). 7) Send the measured value to the instrument using the following comman d: diag:ampl:cal 52 The internal software compares the supplied measured value to the progr ammed value, and adjusts the internal calibration data to null out any differ ences. 8) Observe the voltage across the load again. The amplitude setting sho uld now agree with the measured value. Information on more extensive timing and amplitude calibration procedur es is available at http://www.avtechpulse.com/appnote/. __________________________________________________________________ 30 PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “Programming Manual for -B Instruments” describes in detail how to connect the pulse generator to your computer, and the programming commands themselv es. A large number of commands are available; however, normally you will only need a few of these. Here is a basic sample sequence of commands that might be sent t o the instrument after power-up: *rst (resets the instrument) trigger:source internal (selects internal triggering) frequency 10 Hz (sets the frequency to 10 Hz) pulse:width 100 ns (sets the pulse width to 100 ns) pulse:delay 1 us (sets the delay to 1 us) output on (turns on the output) source:volt 50V (sets the voltage amplitude to 50 Volts) For triggering a single event, this sequence would be more appropriate: *rst (resets the instrument) trigger:source hold (turns off all triggering) pulse:width 100 ns (sets the pulse width to 100 ns) output on (turns on the output) source:volt 50V (sets the voltage amplitude to 50 Volts) trigger:source immediate (generates a single non-repetitive trigger event) trigger:source hold (turns off all triggering) output off (turns off the output) To set the instrument to trigger from an external TTL signal applied to the rear-panel TRIG connector, use: *rst (resets the instrument) trigger:source external (selects internal triggering) pulse:width 100 ns (sets the pulse width to 100 ns) pulse:delay 1 us (sets the delay to 1 us) source:volt 50V (sets the voltage amplitude to 50 Volts) output on (turns on the output) These commands will satisfy 90% of your programming needs. __________________________________________________________________ 31 ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available command s is given below. These commands are described in detail in the “Programming Manua l for -B Instruments”. (Note: this manual also includes some commands that are n ot implemented in this instrument.

With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpow ered for 10 minutes before opening the instrument. This will allow any internal sto red charge to discharge. There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech (info@avtechpulse.com) to arrange for the instrum ent to be returned to the factory for repair. Service is to be performed solely b y qualified service personnel. Caution: High voltages are present inside the instrument during normal operation. Do not operate the instrument with the cover removed. RACK MOUNTING A rack mounting kit is available. The -R5 rack mount kit may be install ed after first removing the one Phillips screw on the side panel adjacent to the front handle. ELECTROMAGNETIC INTERFERENCE To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused ou tputs should be terminated with shielded coaxial terminators or with shielded coaxia l dust caps, to prevent unintentional electromagnetic radiation. All cords and cables s hould be less than 3m in length. __________________________________________________________________ 34 MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require repla cement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compres sed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommend ed. __________________________________________________________________ WIRING DIAGRAMS WIRING OF AC POWER 1 2 3 4 5 6 D o n o t a t t e m p t a n y r e p a i r s o n t h i s i n s t r u m e n t M a i n s c i r c u i t s - h a z a r d o u s l i v e . b e y o n d t h e f u s e r e p l a c e m e n t p r o c e d u r e s d e s c r i b e d M o u n t w i t h M 2 . 5 - 0 . 4 5 X 1 2 . i n t h e m a n u a l .
