Flere are some features that make your new multimeter a real pro: Auto-Ranging with Manual-Ranging Override — automati- cally selects a range when you measure voltage, resistance, capacitance, or current. You can also manually set the range when measuring values you know are within a certain range.
Data Hold Function — the meter holds the displayed value, so you can see the reading even after you disconnect the probes. High-Speed Sampling — ensures quick, reliable measure- ments. All Rights Reserved. RadioShack is a registered trademark used by Tandy Corporation. UL Listed — your meter has passed the stringent safety tests required by Underwriters Laboratories.
Note: The UL mark does not indicate that this product has been evaluated by Underwriters Laboratories for the accuracy of its readings. Latest 1C and Display Technology — ensure reliability, accu- racy, stability, and ease of operation. Zero Function — lets you set the display to zero or to a refer- ence point you select, then measure voltage, current, resis- tance, or capacitance around that reference.
Overload and Transient Protection — helps protect the meter from overvoltage In most ranges. Continuity Buzzer Function — lets you quickly hear if there is continuity in a cable or between two points. Diode Check Function — lets you safely check semiconduc- tors for open, shorted, or normal junctions. Auto-Polarity Operation — protects your meter and gives val- id measurements even when you connect the leads In reverse polarity.
Protective Rubber Boot — protects the meter frem damage and lets you hang the meter on a wall. Note: Your multimeter requires one 9V battery not supplied. But safe operation de- pends on you, the operator. Always disconnect power from the circuit you are measuring before you connect test leads to high-voltage points. Take it to your iocai RadioShaok store. Caution: This terminal is not fuse-protected. A Caution: Risk of electric shock! Refer to the complete operating instructions.
Nominal Current 1. F overflow or OL overload Caution: When o. F appears, it indicates that the measurement exceeds the range for the current setting. When OL appears, it indicates that the measurement exceeds the absolute maxi- mum reading. Specifica- tions are subject to change and improvement without notice. For the best performance and longest life, we recommend a Ra- dioShack alkaline battery.
Doing so might damage the meter or change its calibration. Snap one terminal of a fresh 9 voit battery onto one of the terminais in the battery compartment, then snap the other battery terminai onto the other battery compartment termi- nai.
Caution: Connecting the battery to both of the battery ter- minais at the same time might cause the meter to iock up. The meter turns on. RESET 4. Replace the cover and secure it with the screw. When BATT appears on the right side of the display, replace the - «j — battery. Batteries can leak chemicals that can destroy electronic parts. Use only test leads of the same rating with the meter. You can order replacement leads from your local RadioShack store.
Simply slide the meter into the boot. Use the clips on the back of the boot to store the test leads while you are not using them. The keyhole on the back of the boot lets you hang the meter on a wall. Keyhole 19 In this mode, the meter automatically selects the next higher or lower range if available when the measurement causes the display to overflow the meter tries to display or more units or underflow the meter tries to display or fewer units.
If a voltage or current measurement exceeds units, the meter might display o. For example, 3. Then, if the voltage is increased to 4. F then change the range to the volt range. The tables on Pages 22 and 23 show what the meter displays when set to its different ranges.
If a voltage or current measurement falls below units, the meter might display uf underflow then automatically select the next lower range if available. For example, 4. Then if the volt- age is decreased to 3. Before you use your meter for the first time, follow these steps to familiarize yourself with its operation. Warning: Always turn off power to the circuit you are about to measure before you probe the test leads into high-voltage points. Caution: Be sure to select the correct function before you touch the test leads to the circuit or component to be tested.
RadioShack 21 Repeatedly press RANGE to set the meter to manual rang- ing so you can view the different measurement ranges. Your meter automatically sets itself to the range that gives the best reading. The unit of measure that appears on the display shows you the range that the meter Is currently set to.
For example, mV appears in the mV range and v appears in the V range. Also, note the position of the decimal. For example, if. If v appears, the meter is set to measure up to 1 volts. Read the range in volts, ohms, or amps as Indicated by the position of the deolmal point. Range Display mV ddd. This is normal. When you connect the test leads to a circuit, a real measurement appears. Connect the test leads to the circuit you want to measure.
F overflow appears, the value you are measuring exceeds the range for the setting you selected. This is nor- mal when you measure resistance or a diode, or do not have the leads connected to a component.
If you are mea- suring voltage or current when o. F appears, however, immediately disconnect the probes from the circuit. Immediateiy discon- nect the probes from the circuit.
When you measure current, the meter is preset to automaticaiiy select a range within the limits of the seiector's setting. Whiie this feature is convenient, it might be faster to manuaiiy set the range when measuring vaiues that you know are within a cer- tain range.
To switch to manuai range controi, press RANGE, auto disap- pears and the meter hoids the range at its current setting. To reseiect automatic range controi, press SELECT, auto ap- pears and the meter automaticaiiy seiects the range that gives the best reading.
For example, the meter always shows a small value when you set the selector to HI- to measure capacitance, even when you have not connected the test leads to a compo- nent.
This happens because the meter measures Its own Inter- nal capacitance, which is normal. If you zero the meter. It does not display this value when you measure a component.
You can also set the meter to a baseline reference value called relative measurement. For example. However, to prevent accidentaily ex- ceeding the protection circuit's rating and to ensure a correct measurement, never connect the test ieads to a source of voit- age whiie the seiector is set to Hi- ii, 0.
This couid damage the meter or the circuit being tested. Note: To use the zero feature in higher ranges, manuaiiy seiect the range before you short the ieads together. Foliow these steps to zero the meter or use reiative measure- ment. Touch the test ieads together if you are zeroing the meter or connect the test ieads to the cempenent whese mea- surement you want to use as a reference vaiue if you are using reiative measurement.
Note: Do not short the test ieads together in Steps 2 and 3 if you are measuring capacitance. The meter autematicaiiy subtracts the vaiue en the dispiay from the next measurement you make. Use the meter to make a measurement. This is not a malfunction. A count Is the smallest unit of measure that the meter can measure. For example, If you store Disabling Automatic Power Off To set the meter so It does not turn off automatically, make sure the meter Is turned off.
To turn off the meter and reset it so it automatically turns off the next time you turn it on, follow these steps. DH appears. The meter beeps then turns off. Press any key to turn on the meter. To avoid electrical shock and dam- age to the meter, never try to measure a DC voltage above 1 volts or an AC voltage above volts RMS. Measure the zero offset disconnect test leads for capacitance function, or touch the test leads together for other function if you want to remove the zero offset from reading, or connect the test leads to the component whose measurement you want to use as a reference value.
The meter is set to manual range mode. Use the meter to make a measurement. This is not a malfunction. A count is the smallest unit of measure that the meter can measure. For example, if you store —3. To turn the meter back on after it automatically turns off, press any button.
The meter sets itself to its normal test mode and does not automatically turn itself off. To reset the meter so it automatically turns itself off, turn off the meter then turn it back on. The meter automatically turns itself off after about 30 minutes. To avoid electrical shock and damage to the meter, never try to measure a DC voltage above volts or an AC voltage above volts RMS.
Rotate the function selector to V. If the meter is set to automatic range control, the meter automatically moves to the range that gives the best reading.
Touch the probes to the circuit you want to test. When you measure DC voltage, — appears on the left side of the display if you touched the black probe to a point in the circuit that has a higher voltage potential than the point where you connect the red probe.
To distinguish between the two ranges, mV appears in the mV range and V appears in the V range. The meter automatically selects auto range and the DC measurement mode. Measure the DC voltage to ensure that it does not exceed V.
Turn off the power of the circuit under test. Connect a 0. Apply the power to the circuit. The display shows the AC voltage. Warning: To avoid electrical shock, do not touch the test probes, capacitor, or the circuit under test while applying power. When you finish measuring the AC voltage, turn off the power of the circuit under test, then disconnect the capacitor you connected in Step 6. Most 3-phase power circuits are rated by their line-to-line voltage.
This voltage is higher than the line or phase to ground voltage. To determine if a line-to-line 3-phase voltage exceeds the rating of this meter, multiply the rated line-to-ground voltage by 1. Therefore, you should not connect the meter to this circuit or to any equipment connected to the circuit. Doing so could present a dangerous shock hazard to you, and could also damage the meter. The connection must be in series with the circuit under test. You must connect the meter in series with the circuit.
Apply power and read the current. Remove power from the circuit. Reapply power to the circuit. If the meter does not show a reading in the 0. Doing so can damage the meter or the circuit under test. Remove the power from the circuit under test and discharge all capacitors. Plug the black test lead into —COM and the red test lead into the appropriate jack.
WARNING: Be sure the circuit under test has all power removed and any associated capacitors are fully discharged before you make a resistance measurement. Caution: Your meter has a circuit to protect the resistance range from over-voltage. Remove all power from the circuit under test and discharge all capacitors. Touch the test leads across the circuit you want to measure, or remove one of the leads of the component you want to measure from its circuit and touch the test leads across the component.
If the meter is set to automatic range control, it automatically moves to the proper range. If you set the meter to use manual range, repeatedly press RANGE to set manual-range control and change the range if necessary. The meter measures the amount of time takes to discharge the capacitor.
This could damage the meter or the circuit being tested. Attach the red test lead to the positive side of the capacitor and attach the black test lead to the negative side of the capacitor. Or remove one of the leads of the capacitor you want to measure from its circuit and connect the test leads to the capacitor.
Note: Electrolytic capacitors have positive and negative terminals. Be sure to connect each test lead to the correct terminal to match the polarity of these capacitors. Read the measured value on the display. Since this meter cannot use high voltage to set the electrolyte. It cannot measure the absolute value of capacitance. You can use the meter to check for shorted or open electrical circuits. Touch the test leads across the circuit you want to measure. Shrt appears and the buzzer sounds if the circuit resistance is less than about 50 ohms meaning the circuit is continuous or shorted.
It also lets you determine the forward voltage and polarity for diodes. This is handy when you need to match a diode. You can also check LEDs using this procedure. Connect the test leads to the device you want to check, or remove one of the leads of the component you want to measure from its circuit and connect the test leads to the component.
Note the first reading. Reverse the test leads and note the second reading. If both values are very small or zero, the device is shorted. If the voltage exceeds 2. This means the diode check cannot be made using this meter. Then reverse the test leads and measure and note the second reading.
The amplitude of a signal is not larger than 10V peak. Connect the black test probe to a ground reference for the signal, and connect the red test probe to the signal source. This lets you easily detect a break in an electric circuit or locate the source of an electric field. Note: Varying construction materials and methods give unreliable results for measuring an electric field behind a wall. Do not attempt to measure voltage on in-wall or other premises wiring. Rotate the function selector to EF.
Remove the test leads. Hold the meter so the built-in antenna inside the top of the meter is near the object you wish to examine. Do not touch the meter to the object being tested. Note: For the best sensitivity, hold the meter behind the function selector.
If the meter detects an electrical field, 1 to 5 bars appear on the display corresponding to the strength of the field , and the meter buzzes. EF appears but no bars appear if the electrical field is weak.
Use and store the meter only in normal temperature environments. Handle the meter carefully; do not drop it. Keep the meter away from dust and dirt. If your meter is not performing as it should, take it to your local RadioShack store for assistance.
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the meter. If the fuse is blown, discard it and save the ribbon. Then remove the spare fuse from the plastic holder and insert it into the fuse holder through the loop of the attached ribbon. Replace the back cover and secure it with the screws.
The spare fuse is inserted into plastic holder on the top cabinet near the terminals. The fuse is a mA, V ceramic fuse Cat.
Caution: Do not use a fuse with ratings other than those specified here. Doing so might damage your meter. Remove the battery.
Use a Phillips screwdriver to loosen the screws in the back cover and lift off the cover. Caution: The battery line connects the back cover and the top cabinet together. Do not try to remove the back cover.

To turn off the meter and reset it so it automatically turns off the next time you turn it on, follow these steps. DH appears. The meter beeps then turns off. Press any key to turn on the meter. To avoid electrical shock and dam- age to the meter, never try to measure a DC voltage above 1 volts or an AC voltage above volts RMS. Follow these steps to measure AC or DC voltage. Touch the test leads to the circuit you want to test. If the meter is set to automatic range control, the meter automat- ically moves to the range that gives the best reading.
Note: In the V and mV ranges, the decimal point appears In the same position one place to the left. To dis- tinguish between the two ranges, mv appears in the mV range, and v appears in the V range. Follow these steps to measure an AC voltage superimposed on a DC voltage source bias. Touch the test leads to the circuit you want to test and note the reading. The display shows the DC voltage. Disconnect the test leads from the circuit. Remove power from the circuit under test and discharge all capacitors.
Connect a 0. Connect the black test lead to ground, then connect power to the circuit you want to measure and note the reading.
The display shows the AC voltage. Warning: To avoid electric shock, never touch the circuit and test terminals while testing. When you finish measuring the AC voltage, disconnect the power from the circuit under test then disconnect the capacitor you connected in Step 8. Most 3-phase power circuits are rated by their line-to-line volt- age. This voltage Is higher than the line or phase to ground voltage. To determine if a line-to-line 3-phase voltage exceeds the rating of this meter, multiply the rated line-to-ground voltage by 1.
If the rated line-to- ground voltage is volts, the line-to-llne voltage Is x 1. Therefore, you should not connect the meter to this circuit or to any equip- ment connected to the circuit. Doing so could present a danger- ous shock hazard to you, and could also damage the meter.
The con- nection must be in series with the circuit under test. Make measurements within 30 seconds after you connect the meter to the circuit and allow the meter to cool for 15 minutes between measurements. Doing so can damage the meter or the circuit under test. Set the selector to 0. Plug the black test lead into the -COM jack and the red test lead into the appropriate jack. Apply power and read the current. Reapply power to the circuit.
