Power management
Display illumination can be switched off.
The test instrument is switched off
automatically after the last key opera-
tion. The user can select the desired
on-time.
Safety shutdown If supply voltage is too low (U < 8.0 V),
the instrument is switched off, or can-
not be switched on.
Recharging socket Installed, optional rechargeable batter-
ies can be recharged directly by con-
necting a charger to the recharging
socket:
Z502R charger
Charging time Approx. 2 hours *
* Maximum charging time with fully depleted rechargeable batteries.
A timer in the charger limits charging time to no more than 4 hours.
