  • Page 10: Battery Installation

    BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery/fuse cover. 1. Disconnect the test leads from the meter. 2. Remove the rubber holster (if in place). 3. Remove the two screws securing the rear cover using a Phillips head screwdriver.

  • Page 11: Operating Instructions

    OPERATING INSTRUCTIONS WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care. 1. ALWAYS turn the function switch to the OFF position when the meter is not in use. 2. Press the HOLD button to freeze a displayed reading NOTE: On some low AC and DC voltage ranges, with the test leads not connected to a device, the display may show a random, changing reading.

  • Page 12: Ac Voltage Measurements

    AC VOLTAGE MEASUREMENTS WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage on it.

  • Page 13: Ac/dc Current Measurements

    AC/DC CURRENT MEASUREMENTS CAUTION: Do not make high current measurements on the 10A scale for longer than 15 seconds followed by a 15 minute cool down period. Exceeding 15 seconds may cause damage to the meter and/or the test leads. 1.

  • Page 14: Resistance Measurements

    RESISTANCE MEASUREMENTS 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive jack. 2. Set the function switch to the position. 3. Touch the test probe tips across the circuit or part under test.

  • Page 15: Temperature Measurements

    TEMPERATURE MEASUREMENTS WARNING: To avoid electric shock, disconnect test leads from any source of voltage before making a temperature measurement. Be sure that the thermocouple has been removed before changing to any other measurement function. 1. Insert the type K thermocouple probe into the Temp and COM jacks.

  • Page 16: Diode Test

    DIODE MEASUREMENTS 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V/ /mA jack. 2. Turn the rotary switch to the •))) position. 3. Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V.

  • Page 17: Maintenance

    MAINTENANCE WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery/fuse cover. WARNING: To avoid electric shock, do not operate your meter until the battery/fuse cover is in place and fastened securely. This Multimeter is designed to provide years of dependable service, if the following care instructions are performed.
