English
The CA 6503 is an electrical measuring instrument intended for insulation
measurements (1 to 500MΩ at 250 or 500VDC and 10 to 5000MΩ at 1000VDC).
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.
