APPLICATIONS:

The C.A. 6240 allows quick detection of any deterioration between 2 contact points. This means it can be used for a very broad range of applications:

• Contact resistance of switches and circuit breakers

• Earth continuity

• Quality of weld spots

• Surface condition and metallizing

• Graphite electrode…

The C.A. 6240 micro-ohmmeter provides reliable, accurate measurements due to its test current of up to 10 A. This accuracy is ensured through:

• use of the 4-wire method which eliminates the effects of the leads' resistances and the contact resistances.

• the possibility of reversing the polarity of the measurement current, thus eliminating the effects of possible interference voltages.
