The current measurement has 2 measurement positions
on the rotary switch:
A
and
mA
.
The
A
has a 8.0000A and 10.000A range, with
autoranging;the
mA
has a 80.000mA and 800.00mA
range, with auto ranging.
To measure current, connect the Meter as follows:
1. Turn off power to the circuit. Discharge all high-
voltage capacitors.
2. Insert the red test lead into the
A
or
mA
terminal
and the black test lead into the
COM
terminal. Use
the
A
terminal and
A
range if the current value to
be tested is an unknown.
3. Set the rotary switch to
A
or
mA
.
4. The Meter defaults to DC current measurement
mode. To toggle between
DC
and
AC
current
measurement function, press .
5. Break the current path to be tested. Connect the
red test lead to the more positive side of the break
and the black test lead to the more negative side
of the break.
6. Turn on power to the circuit.
The measured value shows on the display.
The AC current value displayed is a True RMS value.
