13.1.1 Measurement with Positive Half-Waves (PROFITEST

MTECH+, PROFITEST MXTRA only)

Measurement by means of half-waves plus direct current makes it

possible to measure loop impedance in systems which are

equipped with RCCBs.

In the case of DC measurement with half-waves, selection can be

made between two variants:

DC-L: Reduced bias current

but faster measurement as a result

DC-H: Higher bias current providing more reliability with regard

to non-tripping of the RCD

Set Parameters

* Parameters used for report generation and do not influence the mea-

13.2 Evaluation of Measured Values

The maximum permissi-

ble loop impedance Z

L-

which may be dis-

played after allowance

has been made for the

instrument’s maximum

measuring and intrinsic

uncertainties (under nor-

mal measuring condi-

tions) can be determined

with the help of Table 1

on page 100. Intermedi-

ate values can be inter-

polated.

The maximum permissi-

ble nominal current for

the protective device (fuse or circuit breaker) for a line voltage of

230 V after allowance has been made for maximum measuring

error can be determined with the help of Table 6 on page 101

based on measured short-circuit current (corresponds to IEC

60364-6).
