Measuring Current with the Internal Current Shunt
MEASURING CURRENT WITH THE INTERNAL CURRENT SHUNT
WARNING:
Exercise care when connecting in series with a circuit, especially those containing motor(s). Sudden disconnects may create
higher than expected voltages due to inductive kick.
WARNING:
Perform a Fuse Check before measuring currents with the internal
current shunt. Exercise caution in determining whether a circuit is "live" if the
meter does not report a current. This may indicate either a poor connection or
a blown fuse.
NOTE: AC current range is limited by the instantaneous current. Peaks above
the listed limits will result in incorrect readings. Derate AC current limits with
high crest factors accordingly.
§
Disconnect power from the circuit to be measured.
§
Break the circuit and wire the meter in series through the "A" and "C"
terminals.
§
Positive DC current flows into the "A" terminal.
