Figure 6.23: Uncompensated and compensated test result
Notes:

The compensation value is correct only for the output at which it was carried out.

The compensation of test leads is carried out with set test current (I out).
6.2.2.2 Limit Calculator
It is useful tool to determine continuity resistance high limit, especially when testing mains
power extension cords with or without PRCDs.
Limit calculator is included in Continuity and PE_conductor (PRCD) functions and can be
accessed from options panel.
Limit Calculator screens are presented on
Figure 6.24 .
Figure 6.24: Limit Calculator screens
Three Limit rules are offered:
A: VDE / In < 16A
Continuity and PE_conductor(PRCD) resistance limit is derived from table on wire length basis.
Table is based on VDE 0701-0702 standard for nominal current In < 16A.
L wire length R Limit [

L <= 5 m 0.3
5 m < L <= 12.5 m 0.4
12.5 m < L <= 20 m 0.5
20 m < L <= 27.5 m 0.6
27.5 m < L <= 35 m 0.7
35 m < L <= 42.5 m 0.8
42.5 m < L <= 50 m 0.9
50 m < L <= 57.5 m 1.0
