Mechanical Specifications - Chauvin Arnoux C.A 41 Bedienungsanleitung

Adherence to standards
Class III instrument in accordance with IEC 248.
- Electrostatic discharge (IEC 801-2 and IEC 1000-4-2)
Class of severity:
level 2 (4 kV) no desctruction of build components, but change of function that can be reset by a new
instruction.
level 4 (15 kV) non destructive.
- Radiated electrical fields (IEC 801-3 and IEC 1000-4-3)
Class of severity: level 4 (200 V/m).
Power supply
The power supply of the instrument is produced by a 9 V battery type 6 LF 22.
Voltage range ensuring correct operation: 6,5 V to 11 V.
- Display of symbol
- Display of symbol
minutes).
- Display of «bAt» symbol and auto OFF for a battery voltage < 6,5 V (no operation possible, the battery
must be changed).
Average service life: 30 hours in continuous operation without use of the demodulation function. Each
time the instrument is switched ON, the remaining service life (3) as a percentage of the capacity appears
on the display of the C.A 41.
