5. DC Current Measurements

To measure current you interrupt the circuit to be measured and
turn the meter in this circuit in series with the consumer. Please
note when measuring current: the maximum current that can be
measured without damaging the device is 10 A
maximum of 10 seconds) respectively 200 mA
the selected range. Never connect a voltage source to the test
sockets of the meter when the current measurement function has
been selected. A sufficiently powerful power source may lead to a
short circuit with fire and burns.
If the value of the current to be measured is unknown, use the
maximum measurement position (10 A

measured is not known beforehand, select the highest range
and then reduce the range step by step until satisfactory
results are obtained.
3. Turn off the power to the circuit. Discharge all high-voltage
capacitors.
4. Break the current path to be tested. Connect the red test lead
to the more positive side of the break and the black test lead to
the more negative side of the break (in series with the circuit).
5. Turn on power to the circuit and read the display. The polarity
is indicated as well.
