AC and DC Current Measurements
XWWarning
To prevent possible electrical shock or
personal injury, do not make an in-circuit
current measurement where the open-circuit
potential to earth is >1000 V. Meter damage
or injury can occur if the fuse blows during
such a measurement.
WCaution
To prevent possible damage to the Meter or
to the equipment under test:
• Do a fuse test before current
measurements.
• Use the correct terminals, function, and
range for all measurements.
• Do not put the probes across (in parallel
with) a circuit or component when the
test leads are connected to the current
terminals.
To measure current, you must break the test circuit, then
put the Meter in series with the circuit.
The current ranges are 6.000 A, and 10.00 A. AC current
is shown as an rms value.
To measure current (see Figure 6):
1. Remove power from the circuit. Discharge all high-
voltage capacitors.
2. Put the black test lead into the COM terminal. Put the
red test lead into the A terminal.
3. Set the function switch to  for ac current or  for
dc current.
