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.
c. Measuring DC 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 present. Instrument damage and/or
personal injury may result.
Instrument set-up:
FUNCTION BLACK RED MINIMUM MAXIMUM
TEST LEAD TEST LEAD READING READING
COM mA 0.001mA 500.00mA
COM A 0.0001A 10.000A
Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the
COM
input jack.
3. Plug 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 or function.
5. Connect the test leads in series to the circuit to be
measured.
6. Reconnect power to circuit to be measured.
7. Read the current on the LCD.
