Measuring AC or DC Current

XWWarning
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 > 1000 V.
Check the Meter's fuses before testing. See
Testing the Fuses later in this manual.
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 current terminals.
Turn power OFF to the circuit under test, break circuit,
insert Meter in series, turn power ON. To measure ac or
dc current, set up the Meter as shown in Figure 12.
