Dc Current Measurement - Clas Ohlson UT132E Bedienungsanleitung

Note:
In each range, the meter has an input impedance of 10 MΩ except the mV range,
which has an input impedance of 3000 MΩ. This can cause measurement errors
in high impedance circuits. If the circuit impedance is less than or equal to 10 kΩ,
the error is negligible (0.1 % or less).

5.2 DC current measurement

1. Connect the black test lead to
COM and the red test lead to
mA (for 0–200 mA) or to 10A
(for the range 200 mA – 10 A).
2. Set the multifunction selector
to A .
3. Switch on the multimeter
using [ ].
4. Connect the test leads in series
with the current source to be
measured. Read the value.
5. Switch off the multimeter
using [ ].
Warning!
Do not connect the leads in parallel
with the voltage source when
measuring current!
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 instrument from
overheating.
The interval between two readings must be greater than 15 minutes.
