How to perform low-impedance measurements R LOWΩ
 Select the R
LOW
function by means of the function selector switch.
 Set the sub-function to R LOWΩ.
 Set the limiting value (optional).
 Connect the test cables to the installation tester and compensate the test cable
resistance, if necessary (see section 5.3.3 Compensation (null balance) of the test cable
resistance).
 Make sure that the test object is free of voltage and discharge available capacities.
 Connect the test cables to the test object (see figure 5.9).
 Press the "TEST" key to start the measurement.
 Save the measuring result by pressing the "MEM" key (optional).

Results displayed:
R .............. R LOWΩ – low-impedance resistance
R+ ............ partial result at positive polarity
R- ............. partial result at negative testing polarity
5.3.2 Continuity test with a testing current of 7 mA
This test function can be compared to the continuity test function of a digital multimeter or of a
continuity tester with low testing current. The continuous test is done without polarity reversal
and can be used for testing inductive components.
