Note:
Put in parallel the meter to the load for measurement.
To eliminate the stray voltage, the Loz {Low impedance is about 300kΩ) function of meter
provides a low impedance on the whole conductor circuit so as to obtain much more
accurate measurement value. Turn rotation switch to LoZ, meter displays AC voltage in
main display.
Put in parallel the meter to the load for measurement.
Do not input voltage higher than 1000Vrms. Much higher voltage is possible to be
measured, but the meter may be damaged.
When measuring high voltage, special attention should be paid to avoid electric shock.
In low pass filter measurement mode, meter will automatically change to manual mode.
Press RANGE button to select corresponding range.
Measure the known voltage before using the meter to confirm whether the function of
the product is correct or not.
If open circuit or resistance value of measured resistance exceeds the meter maximum
range, the "0L" will be displayed.
When measuring on-line resistance, turn off all power supplies in measured circuit and
discharge all residual charges on all capacitors before measurement. In this way, the
correct measuring can be assured.
