Digital Multimeter (220-0168) Preparation Faxback Doc. # 7952 with PC Interface INSTALLING/REPLACING THE BATTERY Your meter requires a 9V battery (not supplied) for power. For reliable operation, we recommend an alkaline battery, such as Radio Shack Cat. No. 23-553. Warning: TO AVOID ELECTRIC SHOCK, DISCONNECT BOTH LEADS FROM ANY EQUIPMENT BEFORE YOU REMOVE OR INSTALL THE BATTERY. Follow these steps to install the battery: 1. Turn off power and disconnect the two test probes. 2. Loosen the battery compartment cover screw and slide off the cover. Remove the old battery, if necessary. 3. Place the battery into the supplied insulation capsule and snap it onto the contacts. Warning: Do not discard the provided battery insulation capsule. If you do not use this insulation capsule properly, damage or injury might result. 4. Replace the battery compartment cover and secure it with the screw. WARNING: DO NOT OPERATE THE METER UNTIL YOU REPLACE THE BATTERY AND CLOSE THE BATTERY COMPARTMENT COVER. Notes: When the battery indicator appears, replace the battery. Never leave a weak or dead battery in your meter. Even a leakproof battery can leak damaging chemicals. When you are not going to use your meter for a week or more, remove the battery. USING THE TEST PROBES Use only the type of test probes supplied with your meter. These test probes are rated for 1200 volts. You can purchase replacement probes from your local Radio Shack store. Cautions: Although the test probes are rated for 1200 volts, the maximum rating of your meter is 1000 volts DC and 750 volts AC. If you try to measure DC voltages above 1000 volts or AC voltages above 750 volts, you might damage your meter and expose yourself to a serious shock hazard. Use extreme care when you measure high voltages. Never connect the probe you plug into the COM terminal to a source of voltage greater than 500 volts with respect to each ground. This creates a serious shock hazard. USING THE STAND Use your meter's stand to prop up or hang the meter. Propping Up the Meter If you prop up the meter on a benchtop, the stand helps provide a better viewing angle. To use the stand as a prop, just open it away from the meter and set it on a flat surface. Hanging the Meter To hang the meter, remove the stand by pressing the power parts of the stand together. Then insert the stand into the top two holes as shown. PRE-OPERATION CHECK To ensure correct operation and familiarize yourself with the meter, follow these steps before you use it. 1. Press POWER to turn on the meter. The meter beeps once. 2. Plug the black probe into the meter's COM terminal and the red probe into the meter's V/ohm terminal. 3. Rotate the function selector to MUSIC SYMBOL. Your meter displays OL and the analog bargraph flashes. 4. Touch the probe tips together. Your meter sounds a tone. 5. Rotate the function selector to one of the other OHM positions. Your meter displays a value of less than 1 ohm when you touch the probe tips together. (br/all-11/30/94)
