Dc Current Measurement - Clas Ohlson UNI-T UT131B Bedienungsanleitung

DC current measurement

1. Connect the black test
lead to COM and the red
lead to VmAµA (for
measuring 0–200 mA) or
to 10A MAX (for measuring
200 mA – 10 A).
2. Set the function selector
switch to A .
3. Connect the test leads
in series with the load
and source of the current
to be measured. Read
the displayed value.
Warning:
Do not connect the test leads in parallel with the voltage source when
measuring voltage!
If in doubt about the correct measuring range, start with the highest and
work downwards.
When measuring high currents, the multimeter should only be connected
briefly (less than 10 seconds for currents greater than 10 A). This is to
prevent the shunt inside the instrument from overheating
The interval between two readings must be greater than 15 minutes.
