Disconnect the input power and discharge all high-voliage capacitors through a protective imped- ance before testing in the Q and » functions. © When making a current measurement, turn the power off before connecting the meter in the circu © Check meter fuses before measuring current trans- former secondary or motor winding current. (See “Fuse Test" in the "MAINTENANCE" Section) Anopen fuse may allow high voltage build-up, which is potent- ially hazardous. GETTING STARTED QUICKLY Examine the meter carefully familiarizing yourself with the layout of the input terminals, rotary switch, pushbuttons and display. Notice the WARNING information and summary of Power-on options engraved into the rear panel. Ifyou have used a multimeter before, simply examining your meter will probably give you a good idea how to use it. The following procedure is an overview of how to take basic measurements. WARNING. TO AVOID ELECTRICAL SHOCK OR DAMAGE ‘TO THE METER, DO NOT APPLY MORE THAN 1000V BETWEEN ANY TERMINAL AND EARTH GROUND. Insert the test leads in the appropriate input terminals {see Table 1). If the test leads are in the wrong input terminals when the meter is turned on and the beeper has not been disabled, the beeper will emit a warning. ‘See “Input Terminals and Input Alert”, below. To turn the meter on and select a function, turn the rotary switch from OFF to the appropriate switch position. All segments on the liquid- crystal display (LCD) will turn on for one second, then the meter is ready for normal operation. If you would like to freeze the display with all segments on, press and hold down any button, while turning the meter on. As long as the button is held down, all LCD segments will remain on. To select an additional operation, press the appro- priate pushbuttons above the rotary switch as de- scribed in the items below.HOW TO USE THE METER © To operate the MIN MAX and RANGE buttons: press to select, press again to scroll or increment, and press and hold for two seconds to exit. * To operate the Hz button: press to select the frequency mode, press again to select duty cycle, and press again to exit. © To operate the remaining buttons: press to select and press again to exit, NOTE The response of the display and the pushbuttons slow down in the capacitance mode. An annunciator is displayed when @ mode has been selected. A quick way to reset all the pushbuttons to thelr default state is 10 turn the rotary switch to an adjacent function and then back to the function you are using. 4, To take a measurement, use the test lead probes to make the proper contaots. Remember, insert the meter in the circuit in parallel for voltage and in series for current measurements, Read the measurementon the display. Ifyou did not manually select a range (by using the RANGE button), the range that provides the best resolution is automatically selected. 5. To run a performance check of the meter, turn the ro- tary switch to andconnect atest lead from the Var input to the mA yA input. (If you are using a test probe, {ouch the half of the input contact nearest the LCD.) ‘The display should read 1.000 kQ « 5 digits. With the rotary switch still at©, tost the A fuse (114) by inserting the plug end of the test lead into the A input and test the mA JA fuse (44/1008) by inserting the plug end of the test lead into the mA yA input. The beeper emits an Input Alert i the fuses are good. Although this procedure will allow you to getstarted quickly, ‘we suggest that you take the time to read the remainder of this manual so that you can learn to take full advantage of your meter’s capabilites.

This section discusses some common applications for your rreter, and alerts you to some considerations to keep in mind when taking measurements. Measuring Voltage (AC/DC) To measure voltage, connect the meter in parallel with the Icad or circuit under test. Each of the five ac/de voltage anges presents an input impedance of approximately 10 NQin parallel with less than 100 pF. AC voltage is ac-coupled te the 10 MQ input, To improve the accuracy of de voltage measurements made ir the presence of ac voltages, measure the ac voltage first Note the ac voltage range and manually select a dc voltage range that is the same or higher than the ac voltage range. This method improves the de voltage accuracy by ensuring that the input protection circuits are not being activated. A 'ypical application is measuring the dc offset voltage of an amplifier in the presence of an ac signal. 7HOW TO USE THE METER Holster and Flex-Stand & 4 HOLSTER WITH FLEX-STAND, HOLSTER WITH FLEX-STAND ee LOOPED OVER BELT TGGRED OVER DOG METER IN HOLSTER FACE DOWN (Store Quick Reference Guide under meter) Figure 3.

Present across a component, it will be im- possible to take an accurate measurement of the resistance of that component. The meter measures resistance by passing a known current through the external circuit or component, measuring the voltage drop, and calculating the resistance using Ohm's Law (Q=V/A), Remember, the resistance displayed by the ‘meter is the total resistance through all possible paths be- tween the probes. This explains why in-circuit measurement of resistors does not often yield the ohms value indicated by the resistor’s color code.

Mostin-circuit resistance measurements can be made with- ut removing diodes and transistors from the circuit. The full-scale measurement voltage produced on ranges below 40 MQ does not forward-bias silicon diodes or transistor junctions enough to cause them to conduct. Use the highest range you can (except 40 MM) to minimize the possibility of turning on diodes or transistor junctions. Full-scale mea- surement voltage in the 40-MO range does forward-bias a diode or transistor enough to cause it to conduct. Inresistance (and all other functions except current), the mA uA input is connected to a 1-kilohm resistor. If the mA uA input protection fuse is good, this input can be used as a arial check of proper operation in resistance. The input receptacles have split contacts; touch the probe to the half Nearest the LCD. The 1-kilohm resistor is protected by a 3-diode clamp, Donot apply extemal voltage; it may blow the fuse.APPLICATIONS Measuring Conductance Using Conductance for High Resistance or Leakage Tests Conductance is the inverse of resistance (ie, 1/ohms)andis Measured in units of nanosiemens (nS = 1 x 10” Siemens) The 40-nS range on your meter effectively extends the resistance measurement capability to 100,000 MQ. The 40-nS range can, therefore, be used to test the resistance or leakage in insulators, diodes, transistors, cables, connectors, printed circuit boards, transformers, motors, capacitors, oF other high resistance components, To measute conductance, set the rotary switch to the © function, and press RANGE to manually increment to the 40-nS range. Plug the test leads into the VO-r+ and COM inputterminais, and then connect these leads across the unit under test. The reading displayed is in units of conductance (nS). To convert this reading to megohms, divide the reading into 1000 (1000 /displayed reading innS = MA). Forexample 2.00 nS converts to 500 MQ (1000/2.00). High value resis tance measurements are susceptible to induced noise and may require carelul shielding. To smooth out most noisy readings, enter the MIN MAX Recording mode and scroll to the average (AVG) reading. NOTE Inthe conductance range, there is normally a small residual reading with open test leads. To ensure accurate measurements, connect clean test leads 10 the meter and (with the leads open) read the residual leakage in nanosiemens. Correct subse- quent measurements by using the Relative mode (REL) 10 zero the display, which subtracts the residual from the readings. Diode leakage tests require that the diode junction be reverse-biased when being measured. To do this, connect the anode of the diode to the COM input terminal and the cathode (ring) of the diode to the VO-> input terminal Leakage at the test voltage being applied can then be read in tetms of conductance. High-voltage, stacked diode, assemblies can usually be tested for forward and reverse resistance changes using conductance. These assemblies typically have such high forward voltage drops that the diode test or resistance ‘modes cannot test them. a1APPLICATIONS Measuring Capacitance Noisy Resistance Measurements Your Fluke meteris designed to tolerate up to several volts of ac noise, Noise appears as changing numbers on the digital display and as an oscillating bar graph. Changing the range may reduce the noise. To smooth out the effect of noise on your readings, enter the MIN MAX Recording mode and ‘scroll to the average reading. Measuring Capacitance CAUTION Turn off power and discharge the capacitor before attempting a capacitance measurement. Use the volts de function (7 }to confirm thal the capacitor is discharged. ‘The meter measures capacitance by charging the capacitor with @ known current, measuring the resultant voltage, and calculating the capacitance. The measurement takes about 1 second per range (push button responses also take about 1 second). The capacitor charge can be up to 1.2V. For measuring capacitor values up to 5.0 pi, turn the rotary ‘switch to !Q—I-, press the blue button, and connect the test leads to the capacitor. The meter will select the proper range automatically. Each measurement takes about 1 sec- 2 ‘ond per range. When making repeated measurements of simi- lar values, press RANGE to manually select the proper range and to speed up subsequent measurements. For capacitors less than 5 nF or in noisy environments, use shor test leads ra test fixture. The measurement accuracy of capacitors less than § nF can be improved by first using the Relative mode to zero the display and automatically subtract the residual meter and test lead capacitance. Since the Relative mode also selects ‘mantal ranging, zero the residual capacitance only when ‘measuring small value capacitors. Residual voltage charges on the capacitor, or capacitors with poor insulation resistance or poor dielectric absorption may cause measurement errors. To check capacitors larger than $F, select with the rotary switch (or press the blue button if you are in the capacitance ‘mode). Select an appropriate range from Table 4. Discharge the capacitor, connect the capacitor to the meter, and time the number of secondsit takes for he charge to go from zero to full scale, To estimate the value of the capacitor, multiply the number of seconds times the charge rate uF /sec) in Table 4, For example, a 10 uF capacitor takes about 33 seconds to charge in the 4 MQ range or 33 seconds in the 400 KP range. To reconfirm your estimate, reverse the testAPPLICATIONS. Diode Testing leads; when the capacitor discharges to zero (the analog display polarity switches from ~ to +), start timing the recharge to full scale. Diode Testing ‘To perform a diode or transistor junction test: plug the test leads into the VO->(positive) and COM inputs, turn the rotary Switch to->, and connect the test leads across the diode(s} In diode test, voltage is developed across the component(s) by a test current (approximately 0.6 mA with the test leads shorted) from the meter. Voltage is read on a single 0 to +#3,000V range that can measure up to five silicon diode or transistor junctions in series. For a silicon diode, the typical forward voltage should be about 0.€V. Voltages greater than 3,00V or open test leads produce an overload (OL) reading. I the digital reading is the same in both directions, the diode junction is probably shorted. If the display reads OL. in both directions, the diode junction is probably open. To protect sen- sitive devices, the open test lead voltage from the meter will Table 4. Approximate Charge Rate for Capacitors Range | 4002 | 4ka [40Ka | 400k2] 4MO wisec | 2600 [275 [20 [29 | 029 ot exceed 3.9V. Negative inputs (trom an external power ‘source, for example) are not suppressed. Use the Touch Hold mode (see item 9) to make audible diode tests. When the test leads are placed across the diode, a ‘good diode or transistor junction will cause the meter to beep (and update the display) in the forward-biased direction and remain silent inthe reverse-biased direction. A short or resis tance below about 30 kO will cause a beep in both directions. Wan open is detected, the meter will remain silent in both directions. Using the Analog Bar Graph ‘The bar graph is easy to use and interpret It functions much the same as the needle on an analog meter without the ‘mechanical overshoot inherent in needle movements, The bar graph is especially useful for peaking and nulling. and observing rapidly changing inputs. The bar graph response time is fast, and itcan be used to make approximate adjustments quickly. The 4000-count digital display can then be used for final adjustment. ‘The analog bar graph can also be used for limited diagnostic purposes. In situations where rapidly fluctuating signal levels make the digital display useless, the bar graphs ideal Like the needle on a Volt-ohm-milliammeter (VOM), theAPPLICATIONS. Using the Zoom Bar Graph analog bar graph excels at displaying trends, or slowly changing signals. in addition, in the autorange mode, you ‘can monitor signal change through changing ranges. Many iagnostic routines using the bar graph require practice. You will usually be looking for good or bad signal patterns that ‘occur over some span of time. Noisy resistance measure- ments, for instance, create such patterns. Therefore, familiar- ity with analog bar graph response and movement is necessary to accurately interpret a signal pattern. Compare the bar graph response when making measurements on unit known to be good, to the bar graph response when making measurements on a faulty unit. Using the Zoom Bar Graph When you selectthe Relative mode, the bar graph enters the Zoom mode. In the Zoom mode, the center of the bar graph ‘scale becomes the zero (relative) pointfor the bar graph, and the sensitivity of the bar graph increases by afactor of 10 (ten igital display counts per segment). This mode is ideal for peaking, nulling, zero adjustments, and examining noisy or Unstable inputs. If you want to usé the bar graph in Zoom mode without zeroing the digital display, hold down the REL. button when you turn the meter on, Forfastand accurate zero adjustments, simply shortthe test leads together, press REL, and then connectthe testleads to the circuitunder test When the inputis zero, only a single bar ‘graph segment willbe in the center, When the inputis above zero (positive), the bar graph will be turned on to the right of ‘center; when the inputis below zero (negative), the bar graph will be turned on to the leftof center. The bar graph actslikea senstive zero-centered analog meter. For peaking and nulling adjustments, set the meter to the desired function, connect it to the circuit under test, and press REL. A single bar graph segment will be on in the center. As you adjust for a peak, the bar graph will increase from the center to the right; as you adjust for a null, the bar graph will increase from the center tothe let.the left or right bar graph overange symbol ( ¢ or } )comes on, simply press REL twice to set a new reference and bring the bar graph back to the center. Then continue with your peak or null adjustment, Using the MIN MAX Recording Mode The MIN MAX Recording mode can be used to catch intermittents and turn on or turn off surges, verify per- formance, measure while you are away ("baby sit”), or takeAPPLICATIONS. Using the MIN MAX Recording Mode readings while you are operating the equipment under test and cannot watch the meter. The audible MIN MAX Alert indicates when anew minimum or maximum valuehas been recorded. You can select either a 100 ms or 1 second (high accuracy) “response time” for recording minimum and maximum, readings. The response time is the length of time an input must stay at a new value to record the full change. The ‘normal (default) response time is 100 ms. The 100 ms response time is best for recording power supply ‘surges, inrush currents, and finding intermittent failures. This, mode follows the analog bar graph. (The minimum and maximum excursions of the bar graph get recorded} The high accuracy mode (1 second response time) follows the digital display and can be selected as apower-on option by pressing MIN MAX while turning the meter on. This mode has the full accuracy of the meter and is best for recording power supply drift line (mains) voltage changes, or circuit Performance while line voltage, temperature, load, or some other parameter is being changed, Frequency Counter read- ings are recorded only inthe high accuracy mode. In the MIN MAX Recording mode, the true average of all readings taken since entering MIN MAX is calculated. The average value displayed in both the 100 ms and 1 s modesis the mathematical integral of the input (within the response time and accuracy specifications of the meter). When you display the average, the reading rate slows somewhat in order to calculate the average of the accumulated readings. ‘The average reading is useful for smoothing out unstable or changing inputs, calculating power consumption (such as kilowatt hours), estimating the percent of time a circuit is operational, or verifying circuit performance (or temperature with the optional 80TK Thermocouple Module), I you want to record readings only during the duration of a particular test (such as during the frequency response sweep of an audio amplifier, for example), apply the input signal, start the test (or sweep, in this example), and let the meter stabilize. Now press MIN MAX, then press HOLD, and stop the test. The minimum, maximum, and average of all readings taken during the test are now held in memory. Momentarily press MIN MAX to scroll to the reading of interest. Be carefut-if you hold down the MIN MAX button for longer than a second, you will exitthe MIN MAX Recording mode and erase the memory. As long as the rotary switch is. not turned and the other pushbuttons (except REL) are not 25APPLICATIONS ‘Measuring Frequency pressed, these readings will remain in memory until the battery dies. ‘Measuring Frequency In the Frequency Counter mode, the frequency display autoranges to one of five ranges: 198.99 Hz, 1999.9 Hz, 19.999 kHz, 199.99 kHz, and greater than 200 kHz. For frequencies below 10 Hz, the update rate slows and follows the input signal. For frequencies between 0.5 Hz and 0.3 Hz, the display may not be stable. For frequencies below 0.3 Hz, the display shows 0.000 Hz For most requency measurements, turn the rotary switch to the Veotting, connactthe meterto tha signal being measured, and then press the Hz button. Connecting the meter fo the Signal betore pressing Hz wil normaly alow the meter to autorange to an appropriate range, but the minimum input Signal required to trigger the frequency counter varies, depending onthe range and frequency (see Specifications). ifthe input signal Is below the trigger level, frequency measurements. will not be taken. If your readings are Unstable, the input signal may be near the trigger level for that range. You ean usualy correct tis by selecting a lower range Inthe Frequency Counter mode, the range (displayed in the iower-right comer of the LCD) will nly change when you press the RANGE button 26 Ityour readings seem to be a multiple of what you expected, your input signal may have distortion or ringing. (For example, electronic motor controls distort both voltage and current waveforms) Select a higher input range if you suspect multiple triggering. An alternative isto turn the rotary switch to theV or av setting, which will siftthe trigger level fromOV to a positive voltage that changes with each range. In general, the lowest frequency displayed is the correct one. In the Frequency Counter mode, the input range acts like an attenuator, the ¥ function ac-couples the input signal, and the ¥ and iv functions de-couple the input signal. The V {unction is optimized for triggering on logic and switching signals. The 4V de range is optimized to trigger on all ‘common 8V logic families (triggers at 1.7V :t 0.1V). High frequency logic signals may require the use of the 400 mV ac range. The 40V de rangeis optimizedto trigger on automott switching signals (triggers at 4V =1V). All ranges in the 7 function trigger at approximately 10% of range, except for the AY range, Frequency measurements can be made on current inputs. ‘The inputs are always do-coupled, The triggering character- istics are shown in Table 5,APPLICATIONS. Measuring Duty Cycle Measuring Duty Cycle Duty Cycle (or duty factor) isan alternate Frequency Counter mode that displays, in percent, the time the input signal is above the trigger level (or below the trigger level if the negative trigger slope is selected). The Duty Cycle mode is optimized for measuring the on or off time of logic or switching controls. Many industrial control systems (elec- tronic fuel injection in automobiles, for example) are pulse- width modulated, and duty cycle measurements provide a quick check on their performance, For logic level signals, use the 4V de range. For 12V switching signals in automobiles, use the 40V de range, For Table 5.

(Normally, a clean signal can be up toten times the amplitude of the range youare on.) Duty cycle ‘measurements can also be used as an indication ofpotential triggering problems on sine wave or near sine wave signals. lf you do not measure approximately 50% duty cycle, you may have a distorted waveform, In Duty Cycle (and Frequency Counter) mode, the slope (or ledge) on which the counter triggers is selected by pressing the op button. The slope selected is indicated by a + or -annunciator in the lower-left corner of the LCD. The wave- form shown in Figure 4 represents the duty cycle measure- ment of a typical logic signal ‘The manner in which your meter takes duty cycle measure- ments allows it to be very tolerant of aperiodic (repetitive but not periodic) signals. Duty cycle measurements on low frequency (<400 kHz) aperiodic logic signals, especially serial communication signals, is a simple form of signature analysis. A known pattern will read the same duty cycle every time (if the pattern repeats in less than 1/3 second) The precision and resolution of the duty cycle measurements. are achieved by averaging many repetitions of the input signal. In rare cases, this averaging technique (which is similar to pulse-width averaging in a conventional counter)APPLICATIONS. Measuring Duty Cycle may cause a measurement problem called “aliasing” Alias- ing results when the frequency of the inputsignal happens to be exactly synchronized with the reference crystal oscillator ‘of the meter. This occurs when the frequency of the input signal can be exactly divided into the frequency of the oscillator (131,072 Hz) or one of the oscillator’s harmonics. When they are nearly synchronized, the meter is “blind” to the correct duty cycle, and the display will alternate between incorrect readings. this occurs, and the frequency reading was stable, simply press MIN MAX to select the MIN MAX Record mode and scroll to the average display.
