5.2. CONTINUITY - FOUR WIRE METHOD (RPE-4WIRE)
 Complying with EN 60204-1, continuity of protective bonding circuit between PE terminal and
relevant points of the protective conductor system must be checked by injecting a measurement
current of 0.2 A up to 10 A approx.
 Limit values are the values which correspond to the length, cross section and material of measured
conductor.
5.2.1. R PE-4WIRE DISPLAY EXPLANATION
Adjustable/selectable parameters:
LIMIT - continuity limit mode
STANDARD, 60204 SET Z or 60204 SET L
MODE - measurement mode MANUAL or TIMER
TIMER – measurement time 00:01  60:00, resolution 1 s
LENGTH - wire length 0.1  999.9 m, resolution 0.1 m
SECTION - wire section 1, 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50 or 70 mm 2
WIRE - wire material Cu (Cupper) or Al (Aluminium)
Z LINE - input line impedance 0.001  2.000 , resolution 0.001 
PROTECTION - over-current protection device MCB B, MCB C, MCB D, MCB K, FUSE gG or
FUSE aM
In - nominal current of protection device Depends on selected protection device, see the
chapter 5.1.3. LIMIT VALUE ADJUSTMENT
Figure 8 : Display with R PE-4WIRE test result
1 ..... Selected function.
2 ..... Progress bar, it follows measurement time during the measurement (in TIMER mode only).
3 ..... Measurement current flowing through UUT during the measurement.
4 ..... Measurement screen touch-screen key.
5 ..... LIMIT touch-screen key to select limit mode (STANDARD, 60204 SET Z or 60204 SET L).
Currently selected value (STANDARD mode) or CALC (60204 SET Z or 60204 SET L mode) is
displayed on the bottom of the key. CALC message means the value is calculated.
6 ..... MODE touch-screen key to select operation mode (MANUAL or TIMER). Currently selected mode
is displayed on the bottom of the key. TIMER mode is available only if STANDARD limit mode is
selected.
7 ..... Measurement value (in green colour - result lower than or equal to set limit value, in red colour -
result is higher than set limit value).
8 ..... Real time clock (hh.mm.ss).
9 ..... Unit of measurement result (
).
