5.8 RCD test

The purpose of this test is to ensure proper operation of residual current devices built-in

in appliances and portable residual current devices.

The following measurements and tests can be performed:

Ì Trip-out time, and

Ì RCD autotest.

The instrument is intended for testing of General (non-delayed) RCDs, which are suited

for:

Ì Alternating residual current (AC type, marked with symbol),

PRCD socket of the instrument operates as current sink for fault current which is

sourced on L entry of tested appliance.
