Connect the black test lead to the "
COM
" terminal and the red
test lead to the "
ΩVmA°F
" terminal.
Set the range switch to desired
V
range position. If the
magnitude of the voltage to be measured is not known
beforehand, set the range switch to the highest range first and
then reduce it range by range until satisfactory resolution is obtained.
Select DC or AC voltage measurement with the "
AC/DC
" button
according to the marks beside this button.
Connect the test leads across the source or circuit to be tested.
Read the reading on the display. For DC voltage measurements,
the polarity of the red test lead connection will be indicated as well.

Connect the black test lead to the "
COM
" terminal. Connect the
red test lead to the "
ΩVmA°F
" terminal if the current to be
measured is less than 200 mA. If the current is between 200 mA
and 10 A, connect the red test lead to the "
10A
" terminal instead.
Set the range switch to desired
A
range position.
Select DC or AC current measurement with the "
AC/DC
" button
according to the marks beside this button.
Turn off power to the circuit to be tested. Then discharge all
high-voltage capacitors.
Break the circuit path to be tested, then connect the test leads
in series with the circuit.
Turn on power to the circuit, then read the reading on the display.
For DC current measurements, the polarity of the red test lead
connection will be indicated as well.
