Resistance Measurement; Continuity Test - Powerfix Profi PDM 250 A1 Manuel D'utilisation Et Informations Sur Les Services

Resistance measurement

Ensure that all circuit elements, circuits and components to be measured and other test
objects are completely switched off and discharged. Otherwise, the multimeter could be
damaged.
 Connect the black test lead to the COM jack [5] and the red test lead to the V/Ω jack [6].
 Set the range selector switch [4] to the desired range in the Ω measuring range.
 Connect the test probes [7] to the test object.
 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.
