Current Measurement - VOLTCRAFT VC131 Bedienungsanleitung

f) Current measurement
This measuring function is suitable for measuring mains current.
To prevent possible electric shock, fire or personal injury, switch off the power supply
of the circuit, and then connect the DMM to the circuit in series before measuring the
current.
If the range of the measured current is unknown, always start at the highest
measurement range and switch down to lower ranges if needed.
There are fuses inside "10 A" and "mA μA" input terminals. Do not connect the test
leads to circuits in parallel.
A warning will sound when measured values are out of range >10 A.
Measuring >5 A must only be performed for max. 30 seconds and at 15 minute inter-
vals.
1. Set the function dial to µA
appear on the display.
2. Connect the test leads to the terminals:
- Red test lead to the
- Black test lead to the COM terminal.
3. Connect the test lead probes to the circuit in series.
4. Read the value on the display.
- DC current: The polarity is shown together with the measured value.
5. When finished measuring, disconnect the test leads, power the circuit down and switch the
DMM power OFF.
