4.
Switch
OFF
or disconnect the circuit to be measured from all
power sources, connect the multimeter in series with the
conductor in which the current to be measured flows.
5.
Switch
ON
the circuit. Note the reading.
6.
Switch
OFF
or disconnect the circuit and remove the test
leads from multimeter.
CAUTION
A common abuse of multimeters in to attempt to measure
a voltage while the test leads are still plugged into the
current input terminals. This basically puts a short circuit
across the voltage source since current ranges have a
low impedance. If the voltage source is typically 240VAC
or a 3-phase industrial voltage (415V), very high fault
currents can result. This is why all current input terminal
are fused. If the fuses blow they must only be replaced by
the equivalent ones otherwise the safety of the instrument
may be impaired.
7.
Never apply a voltage between the
COM
terminal and
current terminals.
8.
When switching between current ranges to obtain greater
accuracy and better resolution, completely de-energize the
circuit to be measured before changing the range.
