9.5.8 Cable continuity test
The cable continuity test [}page46] is intended to measure the line resistance.
Requirements
• Approved safety measuring lines
• Please observe the requirements for measuring [}page71].
• The test sample is disconnected from the mains.
• Make sure that you are familiar with the procedure for manual [}page77] and automatic
[}page76] testing.
• Make sure that you know the necessary measuring points.
• The test sample is connected according to the connection diagram.

Connection between test socket, test sample and IECsocket of the device.
Procedure
1. If necessary, adjust the following limits:
– Line length [m]
– Line cross-section [mm²]
– Number of conductors
– Rline per conductor [Ω]
2. Start the test.
The measurement is made continuously, so you have enough time to carry out the test. The
device measures the line resistance of the conductors (L,N,PE) and all conductors in
series.
