To avoid any electric shock and/or damage to the meter, do not attempt a voltage measurement if the voltage (valid value) is 1,000V for DC current or 750V for AC current. To avoid any electric shock and/or damage to the meter, don't attempt to impose between any public terminal and ground any voltage whose valid value is over 1,000V for DC current or 750V for AC current.

measured and fully discharged all high-voltage capacitors. Ohm is the unit of electric resistance (). The measuring ranges of electric resistance of this meter are 600.0, 6.000k, 60.00k, 600.0k, 6.000Mand 60.00M, Measurement of electric resistance 1. Turn the rotary switch to the appropriate position. 2.

the polarity of the test lead is reversed, the meter will display "OL". A normal diode still produces a forward voltage drop of 0.5V to 0.8V; the reverse bias voltage reading depend on the variation in electric resistance of other channels between two pen-shaped meters. 3.2.4 Beep continuity test To avoid the meter or the measured equipment from damage, do not attempt a beep continuity test unless the operator has...

Note: The measurement of a large capacitance requires a given period of stabilization of reading. To avoid damage to the meter, the measurement of a capacitor with polarities requires much attention to its polarity. 3.2.6 hFE measurement To avoid any electric shock and/or damage to the meter, do not attempt a frequency measurement if the voltage is over 36V for DC current or AC current(valid value).

3.2.10 Live line test 1. Turn the rotary switch to the position Live. 2. Connect the test lead in red to Live input socket. 3. When a single test lead is inserted into jack L of power socket or approaches a live conductor, if the meter detects AC voltage, the meter's indicator for the intensity (high, medium and low) of induced voltage signal will be on and the beeper sounds alarms for different intensities.
