NON-INDUCTIVE MODE
withAUTOMATIC trigger
• for measurements on resistors
without a time constant
• for repetitive measurements
in production, helping to gain
considerable time
INDUCTIVE MODE
for measurements on inductive
components (transformers, motors, etc.)
NON-INDUCTIVE MODE
for measurements on resistors with
atime constant of a few ms (contacts,
metallization, etc.)
3 measurement modes
TEMPERATURE COMPENSATION
The value of a resistance varies according to the
temperature. For reliable supervision allowing
the comparison of measurements which are
comparable because they were made in the same
conditions, itis a good idea always to express
a measurement in terms of a given reference
temperature. You can perform this calculation by
simply pressing akey.
PROGRAMMABLE ALARMS
Because an audio signal is sometimes all you
need to interpret and assess a measurement,
it is possible to activate a high and/or low
alarm. If it is overshot, a buzzer sounds
(adjustable volume).
EXTENDED MEASUREMENT
The C.A 6255 is equipped with an internal memory
capable of storing 1,500 measurements. They are
memorized with two indices, OBJ (object) and TEST
(test), which store the results in an ordered manner.
Functions
Resistance of cables
Heating of motors and transformers
Verification of mechanical linkage
4-wire Kelvin measurement method
Measurements on windings
(e.g.transformer) without
overheating of the C.A 6255
Surface finish and metallization
Chassis-earth continuity/bonding test
Quality of the contacts (switches, relays)
Numerous applications
