Presentation; Description Of The Various Parts, Controls, And Functions - Chauvin Arnoux C.A 6501 Notice De Fonctionnement

The CA 6501 is an electrical measuring instrument intended for the measurement
of low resistance values (0 to 100Ω at 5mA
1mA ), and for insulation measurements (0.5 to 200MΩ at 500V
DC
ohmmeter function is protected against the accidental presence of a voltage by a
high-breaking-capacity fuse. A voltage-present indicator serves to make sure that
there is no AC voltage in the circuit to be tested.
This instrument is ready for use at all times because it requires no operating
maintenance. A magneto generator provides the various measurement and
operating voltages.
