Contacts qualified recycle.
s Do not apply more than the rated voltage, as marked on the meter, between the test probes or between any test probe and earth ground., s Use the meter with caution for voltages above 30 Vac rms, 42 Vac peak, or &0 VDC. These voltages pose electrical shock hazards. = Disconnect circuit power and discharge all high-voltage capacitors before feting resistance, continuity and diode, e Do not use the meter around explosive gas or vapor. ¢ When using the test leads, keep your fingers behind the finger guards.

Measuring AC Voltage AL Do not apply on a voltage source higher than AC 250V and use proper range for measurement. Over-range indication: "1, “-1” or a Voo reading exceeds 250, ) Measuring DC Voltage AL Do not apply on a voltage source higher than DC 250V and use proper range for measurement.
Measuring DC Current AA To avoid personal injury or damage 1o the meter: 1. Do not attempt to make an in-circuit current measurement when the open-circuit potential to earth ground exceeds 250V, 2. Switch to proper function and range for your measurement. 3. Do not place the test probe in parallel with a circuit when the test leads are connected to the current terminals. 4. Connect the test leads to the circuit before powering the circuit under test. 5.
Measuring Continuity AA Disconnect circuit power and discharge all high-voltage capacitors before testing continuity. Meter beeps at <100, beeper turns off at>70 2. Measuring Diode AL Disconnect circuit power and discharge all high-voltage capacitors before testing diode. Battery Test AA Applying a voltage source or incorrect battery type under battery test may cause personal injury or damage to the meter. Battery 1.5V range is for dry battery i, not exceeding 2Vdc. The resistance = load is around 508.

BATTERY AND FUSE REPLACEMENT A A Warming To avoid shod, injury. or damage to the meter, disconnect the test head from the measuring circuit before opening case. ONLY use the fuse with the amperage, interrupt, voltage, and speed ratings specified. When replacing the battery and fuse, follow the below steps: 1. Disconnect the test lead probe from measuring circuit. 2. Turn the Meter to OFF position. 3, Remove holster and the screws from the back cover, and then open the back cover. 4.
