d. Measuring AC Amps
CAUTION
Do not attempt to make a current measurement 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 measurement of circuits
with more than 600V (1000V-Only 194)present. Instrument
damage and/or personal injury may result
.

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 into the
or
input jack depending
on the value of current to be measured.
4. Set the rotary switch to the
or
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 LCD.
Application Notes
When measuring the DC current of a
flame controller, follow the steps
under “Measurement Procedure”
above and then proceed with the
following:
•
Set up the meter for
making a µA measurement.
•
Connect the meter to the flame
controller lead by opening the
circuit and inserting the leads in
series with the circuit as shown
in the picture above.
