Measuring AC or DC Current (115, 117)
To avoid personal injury or damage to the Meter:
•
Never attempt to make an in-circuit current measurement when the open-circuit potential to
earth is >600 V.
•
Check the Meter's fuse before testing. See
•
Use the proper terminals, switch position, and range for your measurement.
•
Never place the probes in parallel with a circuit or component when the leads are plugged into
the A (Amps) terminals.
To measure current:
1. Turn circuit power off.
2. Break the circuit
3. Insert the Meter in series with the circuit, and then turn circuit power on.
Measuring Current above 10 Amps (110, 114, 115, 117)
The millivolt and voltage function of the Meter can be used with an optional mV/A output Current Probe to
measure currents that exceed the rating of the Meter. Make sure the Meter has the correct function selected, AC
or DC, for your current probe. Refer to a Fluke catalog or contact your local Fluke representative for compatible
current clamps.
