c. Measuring DC Amps
CAUTION!
Do not attempt to make a current measurement with the
test leads connected in parallel with circuit to be tested.
Test leads must be connected in series with the circuit.
W
ARNING!
Do not attempt to make a current measurement of
circuits with more than 600V present. Instrument
damage and /or personal injury may result.
Instrument set-up:
FUNCTION BLACK RED MINIMUM MAXIMUM
TEST LEAD TEST LEAD READING READING
µA COM mA 0.1µA 4000µA
mA COM mA 10µA 400mA
A COM A 1mA 10.00A
Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the COM input jack.
3. Plug the red test lead into the mA or A input jack
depending on the value of current to be measured.
4. Set the rotary switch to the µA, mA or A function.
5. Connect test leads in series to circuit to be measured.
6. Reconnect power to circuit to be measured.
7. Read the current on the 440.
