Measurement range
GENERAL SPECIFICATIONS
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.
The possibility of memorizing the results and transferring data
by means of the processing software allows users to monitor
the changes in the measurements over time, making the C.A 6240
an essential tool for preventive maintenance.

APPLICATIONS: MEASUREMENT MODE
WIDE MEASUREMENT RANGE
The C.A. 6240 is suitable for all types of measurements (inductive
components, resistances). It is particularly ergonomic due to its
automatic operating capabilities:
• Automatic measurement mode: the measurement is triggered
a
s soon as continuity is established between the 2 measurement
p
oints => consecutive tests are possible without pressing a key.
• A
utomatic recording mode: this mode allows users to store each
measurement result in the memory without having to press a key.
The C.A 6240 possesses 7 measurement
calibres accessible automatically by means of a
rotary switch. Each calibre corresponds to a
current from 10 A (4,000
µΩ ) to 0.01 A (400 Ω )
s
elected automatically.
