 Power supply
The power supply of the instrument is produced by a 9V battery type 6 LF 22.
Voltage range ensuring correct operation: 6.5 V to 11 V.
- Display of symbol ashing 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 «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 43.
Saline batteries, Lithium batteries and rechargeable accumulators are also accepted.
