3. Plug the black test lead into your meter's COM terminal
and the red test lead into your meter's µA/mA or 10 A
terminal.
4. Remove power from the circuit under test and then break
the circuit at the appropriate point.
5. Connect the test leads in series with the circuit.
6. Apply power and read the current. Your meter displays the
current value.
Note: If you see the meter for DC current, "-" appears or
disappears. This indicates the polarity of the measured current.
6.3. Measuring Resistance
WARNINGS!
*
Never connect the test leads to a source of voltage when
you have the selected the OHMS function and plugged the
test leads into the V/Ω/Hz/
*
Be sure that the circuit under test has all power removed
and that any associated capacitors are fully discharged
before you make a resistance measurement.
The resistance measuring circuit compares the voltage gained
through a known resistance (internal) with the voltage
developed across the unknown resistance. So, when you
check in-circuit resistance, be sure the circuit under test has all
power removed (all capacitors are fully discharged).
1. Set the rotary selector to the desired OHM range.
