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 destruction 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 + flashing for a battery voltage < 7.5 V (remaining service life
-
approx. 1 hour).
Display of symbol + continuously for a battery voltage < 7 V (remaining service life
-
approx. 10 minutes).
Display of the " " 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.
