Warning
To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure
voltages higher than 1000V DC/750V AC although
readings may be obtained.
Impedance Changeover Button turn on time must be
3 seconds. To avoid damages to the Meter, please
do not attempt to press the Impedance Changeover
Button when the measured voltage is higher than
250V.
The DC voltage ranges are: 200.0mV, 2.000V, 20.00V,
200.0V and 1000V.
The AC voltage ranges are: 2.000V, 20.00V, 200.0V and
750.0V.
To measure DC & AC voltage, connect the Meter as
follows:
