d. MEASURING AC AMPS
CAUTION!
Do not attempt to make a current measure
ment with the test leads connected in
parallel with the circuit to be tested. Test
leads must be connected in series with the
circuit.
WARNING!
Do not attempt to make a current measure
ment 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 µAmA 0.1µA 4000µA
mA COM µAmA 0.01mA 400mA
10A COM A 0.001A 10.00A
Measurement Procedure:
1. Disconnect power to the circuit to be measured.
2. Plug the black test lead into the COM input jack.
3. Plug the red test lead into the µAmA 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. Press the AC/DC pushbutton to set to AC mode.
6. Connect test leads in series to circuit to be measured.
7. Reconnect power to the circuit to be measured.
8. Read the current on the 183A.
Optional Functions:
RANGE
REC
REL
HOLD
Manually select the appropriate range.
Activate MIN/MAX record mode (page 24).
Scroll between Hz, Duty, and Volts.
Activate REL mode (page 24).
Freeze the reading on the LCD.

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.
WARNING!
Do not attempt to make a current measurement of
circuits with more than 600V present. Instrument
damage and /or personal injury may result.
