Measured Value Memory; Storing Measured Values; Calling Measured Values; Deleting The Measured Value Memory - Benning ST 725 Bedienungsanleitung

Note:
Some portable PRCD types (e.g. PRCD-S, PRCD-K) switch off L, N and PE on all poles so that
the BENNING ST 725 does not detect any connection between the IEC connector J and the
test socket 1 . Testing of these PRCD types must be carried out according to chapter 9.5.1 "Test-
ing of permanently installed RCDs" by connecting the portable RCD (PRCD) to a mains socket
which is not protected by another RCD.
See figure 8b: Testing of portable PRCDs (I
