    3.2.2. Non-contact electric field detector (EF mode) It should be a long-distance In measuring high-voltage. Pay attention to safety Electric field is a special substance exist in the charge and the variable ambient magnetic field. To detector Non-contact electric field (set up and connect the Meter as shown in Figure 3-2): 1) Set the rotary switch to the position of EF/VOLT.

  • Page 13: Continuity Check

    3.2.4. Continuity Check To avoid electrical Shock and/or damage to the instrument, disconnect circuit Power and discharge all high-voltage capacitors before testing for Continuity. Continuity is a complete path for current flow. The beeper sounds if a circuit is complete. These brief contacts cause the Meter to emit a short beep.

  • Page 14: Capacitance Measurement

    In a circuit, a good diode (Si) should still produce a forward bias reading of 0.5V to 0.8V; however, the reverse-bias reading can vary depending on the resistance of other pathways between the probe tips. 3.2.6. Capacitance measurement To avoid electrical shock and/or damage to the instrument, disconnect circuit Power and discharge all high-voltage capacitors before measuring capacitance.

MAINTENANCE This section provides basic maintenance information, including fuse and battery replacement instructions. Do not attempt to repair or service your Meter unless you are qualified to do so and have the relevant calibration, performance test, and service information.

  • Page 19: Battery Replacement

    5.3. Battery replacement To avoid false Reading, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator ( ) appears. Before replacing the battery, disconnect test leads and/or any connectors from any circuit under test, turn the meter off and remove test leads from the input terminals.
