Plug the red Test Lead into theVΩmA (Center) Jack. Plug the blackTest Lead into the Com (Bottom)Jack. Switch the Multimeter ON.3. Connect the red probe to the anode ofthe diode and the black to the cathode.4. The approximate forward voltage drop ofthe diode will be displayed in mV.

Never usethis setting to test automotive or lead-acidbatteries. The high current could causedamage to the meter and/or cause severepersonal injury. Use the appropriateDC Voltage setting to test the open circuitvoltage of such batteries instead.1. Turn the Range Selector Switchto the Battery ( ) position.2. Plug the red Test Lead into theVΩmA (Center) Jack. Plug the blackTest Lead into the Com (Bottom)Jack. Switch the Multimeter ON.3. Connect the red probe to the positiveterminal of the battery and theblack to the negative terminal.4. The battery amperage under a load of 370mW will be displayed to a resolution of .1mA.5. Normal amperage:For a standard 9V (6LR61) battery = 25 mA6. For a 1.5 V “AA” (LR6) battery = 4 mA7. To prevent accidents, turn off thetool and disconnect its power supplyafter use. Clean, then store the toolindoors out of children’s reach.User-Maintenance InstructionsProcedures not specifically explained in this manual mustbe performed only by a qualified technician.TO PREVENT SERIOUS INJURY FROM ELECTRIC SHOCK:Turn the Power Switch of the tool to its “OFF” position and remove the test leadsbefore performing any inspection, maintenance, or cleaning procedures.Cleaning, Maintenance, and Lubrication1.
