1.
Set the function switch to one of the following positions:
(
VDC) or (VAC) for high voltage
measurements. Short press MODE to
switch to VFD mode for VAC
measurements. Press again to exit.
(milli-volts) for low voltage
measurements. Short press MODE to select
AC or DC for milli-volt measurements.
2.
The
indicator appears for AC
measurements. The
indicator appears
for DC measurements.
3.
Insert the black probe lead into the
