The measurement result is then indicated on the display [1].
For resistances > 1MΩ, the measurement may take a few seconds. In this case, wait until the
measured value has stabilised.
The test probes [7] should be handled only behind the finger protection to avoid a distorted
measurement result.
For measurements of low resistances (200Ω range), the internal resistance of the test leads
can lead to a distorted result. To avoid such an error, note the value of the measurement for
short-circuited test probes and deduct this from the value of the actual measurement.
Continuity test
