5.2 DC and AC Current measurement
1. Connect the black test
lead to
and the red
test lead to
(for 0–600 mA) or to
(for the range
600 mA – 10 A).
2. Set the function selector to
,
or .
3. The meter is preset to
measure DC, change to AC
using the blue button (10).
4. Connect the test leads in
series with the current source
to be measured.
5. When measuring current
between 600 mA and
10 A (without fuse) follow
the method above but
connect the red test lead to
instead.
6. The true RMS value will be
displayed.
7. Press [ Hz % ] to obtain
the frequency and Duty
Cycle value.
Input amplitude:
≥ range × 30 %
Frequency response: ≤ 1 kHz
Warning:
• If in doubt about the correct range, start with the highest and work downwards.
• When measuring high currents, the meter should only be connected briefly (less
than 10 seconds for currents over 5 A). This is to prevent the shunt in the meter
from overheating.
• The interval between two readings must be greater than 15 seconds.
