7.2. Current measurements
These are made in series with the test circuit. All the current to be
measured flows through the multimeter.
Warning!
Do not attempt to measure currents in high energy circuits capable of
delivering greater than 250V. Damage of the multimeter or injury could
occur.
The current input is protected by a corresponding fuse. When
connecting a voltage source to this input may result in injury and danger
of damage to the unit.
1. Insert the BLACK test lead in the COM input terminal.
2. For measuring currents less than 400mA, connect the red test lead
to the mA input terminal. For measuring currents between 400mA
and 10A connect RED test lead to the 10A terminal.
3. Select the desired current range and select AC/DC by pressing
SELECT-button.
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.
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.
