6.4 Calibration
After the calibration period has been exceeded, a corresponding message appears when the device is
switched on.
In accordance with test specification TP BF-StB Part B 8.3, the Light Weight Deflectome-
ter must be calibrated annually (outside Germany, different regulations may apply). Please
contact your local ZORN partner for this.
6.3 Protection against Deep Discharge (ZFG 3000)
The measuring device is equipped with a deep discharge protection for the battery pack, i.e. in case of
deep discharge the battery is switched off. The settlement measuring device can then no longer be
switched on. Connecting the charger will recharge the device and it will be ready for use again after
approx. four hours.
