OPERATION
a) DC (---) and AC voltage measurement
If there’s more than one function at a position in the rotary switch, press the blue
button to select the required measurement function.
DC voltage ranges are 400mV/ 4V / 400V / 1000V.
AC voltage ranges are 4V / 40V / 400V / 750V.
To measure DC and AC voltage, follow these
steps:
1. Plug red testing lead into HzV Ω and black
testing lead into COM.
2. Set selector switch to V, press blue button to
select DC or AC measure.
3. Plug test lead to the desired device. The DC or
AC value will be displayed in the screen.
-In each range, the meter has a 10 Mohms input. This load effect may
cause measure mistakes while testing high impedance circuits.
If the impedance of the circuit is less or equal to 10 k
Ω , the error will be
less than 0.1%
