Note:
• If the range of the measured current is unknown
before measuring, select the maximum range
and then gradually reduce the measuring range
until the multimeter shows an accurate reading.
• If the or A terminals are overloaded,
the internal fuses will be damaged and must be
replaced (with fuses of the same specification).
• If the test current is close to 10A, each
measurement time should be less than 10
seconds. Wait 15 minutes before measuring
again.
DC/AC Current Measurement
WARNING
• Before measuring, switch off the
power supply of the circuit, and
carefully check the input terminals and
the dial position.
• To avoid electric shock or damage to
the multimeter, never connect the
test leads with any voltage circuit in
parallel during current measurement.
1. Turn the rotary dial to the appropriate
DC/AC current position. Press SELECT to
choose AC or DC current test. [Figure 7.1]
2. Insert the black test lead into the COM
terminal, and the red test lead into the
or A terminal.
3. Connect the test leads in series to the
source or circuit being measured. Hold
them in place until the reading on the
display stabilizes.
