Resistance Measurement; Continuity Test - Powerfix Profi PDM 300 A1 Bedienungsanleitung Und Serviceinformationen

POWERFIX PDM 300 A1

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 mA/Ω/BATT
jack [9].
 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.
For measurements of low resistances (200Ω range), the 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

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.

jack [9].

 If the resistance is less than approximately 30Ω, the buzzer sounds and the measurement
result is indicated on the display [1].
