To measure DC or AC Voltage, connect the Meter as follows:
1. Insert the red test lead into the HzVΩ (UT58C)
or
VΩ (UT58A/UT58B) terminal and the black test
lead into the COM input terminal.
2. Set the rotary switch to an appropriate measurement
position in V or V range.
3. Connect the test leads across with the object to be
measured.
The measured value shows on the display.
Warning
Never attempt an in-circuit current measurement
where the open circuit voltage between terminals
and ground is greater than 250V .
If the fuse burns out during measurement, the Meter
may be damaged or the operator himself may be hurt.
