6.2. Measuring DC/AC Current
WARNING!
* Do not apply voltage directly across the terminals. You
must connect the meter in series with the circuit.
* The 10A terminal is fused. A severe fire hazard and
short circuit danger exists if you apply a voltage with
high-current capability to this terminal. The meter can be
destroyed under such conditions.
To measure current, break the circuit and connect the
probes to two circuit connection points in series. Never
connect the probes across a voltage source in parallel.
Doing so can blow the fuse or damage the circuit under test.
Note: The maximum input current is 0,5 A or 10A
depending on the terminal used. In the 10A range excessive
current flow blows up the fuse, which must be replaced.
1. Set the rotary selector to the desired A range. If you do
not know the current level, set it to the highest position
and reduce the setting as needed to get a reading.
2.
Plug the black test lead into your meter’s COM terminal
and the red test
lead into your meter’s mA or 10A
terminal.
3. Remove power from the circuit under test and then
break the circuit at the appropriate point.
4. Connect the test leads in series with the circuit.
5. Your meter displays the measured current value.
Note: In
DC current, “-” appears or disappears. This
indicates the polarity of the measured current.
