)
1. Set function
2. Set sub-function, parameters and limits.
Z
S
Loop impedance:
Zs
(for systems without RCD)
Zs
rcd
(for systems with RCD)
Fuse type
[---, gL/gG, gG, B, C, K, D]
Nominal current
of the fuse
Tripping time
of the fuse
3. Connection diagrams
Connecting the "Commander" test plug (044149) and the 3-wire test lead
4. Press the key
.
5. The measuring result can be stored by means of the "MEM" key.
Zs
..... Loop impedance (L-PE)
Isc
.... prospective short-circuit current (fault current)
Lim
.. lower limiting value of the prospective short-circuit current
