Continuity Measurement - Chauvin Arnoux C.A 6710 Notice De Fonctionnement

J
T
Continuity can be measured using the following instruments:
- C.A 6115N
- C.A 6511/13
- C.A 6521/23/25.
MEASUREMENT:
Connect the measurement instrument between points W (earth terminal) and F (earth bar of the building).
- if C.A 6115N: use the cable with 3 separate leads and connect the instrument to the measurement terminals with lead L1/L
and the L2/N lead linked to the L3/PE lead.
- if C.A 6511/13 or C.A 6521/23/25/31/33: use the set of 2 red + black leads with banana plugs on the end.
Vary the resistance and the inductance of the PE earth conductor by adjusting switch J.
Activate measurement.
In the field, this is how electricians work when they want to make sure that the earth bar is connected to all the earths (earth
terminals of the sockets, electric radiators, lights, etc.).
To make use of another variable resistance in the case's measurement circuit, connect up between points W and T, not
forgetting to connect a terminal of the earth bar F to one of the earth rods E or ES.
