6.2. Measuring AC/DC Current
Warning!
* Do not apply voltage directly across the terminals. You must connect
the meter in series with the circuit.
* The 10 A 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. 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 0,2 A or 10 A depending on the
terminal used. In these ranges excessive current blows the fuses, which
you must replace.
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 10 A 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. Apply power and read the current. Your meter displays the current
value.
Note: If you see the meter for DC current, "-" appears or disappears. This
indicates the polarity of the measured current.
