Snap-On EEDM504D - Measuring AC Voltage (ACV); Measuring DC Current (DCA)

1514
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
40µA COM µAmA 0.01µA 40µA
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 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 40µA, µA, mA, or A
function.
5. Connect test leads in series to circuit to be measured.
6. Reconnect power to the circuit to be measured.
7. Read the current on the EEDM504D.
Optional Functions:
b. MEASURING AC VOLTS
CAUTION!
Do not attempt to make a voltage measurement if a
test lead is plugged in the A or µmA input jack.
Instrument damage and/or personal injury may
result.
W
ARNING!
Do not attempt to make a voltage measurement of
more than 750V or of a voltage level that is
unknown.
