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.
d. Measuring AC Amps

FUNCTION
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.
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.
