4.6.12 Subsequent Dead Load Correction
If the vessel weight changes by an amount that is higher than the zero-setting range, e.g. due to dead load
reduction, dead load increase or mechanical changes, the functions for automatic zero tracking and manual
zero setting no longer work. To view the range which is currently being utilized for zero tracking or zero
setting, press
. This also activates 10-fold increased resolution of the weight value. Press again to return
to the previous state:
Current zero set: 0.00001 t
If the full zero-setting range is already being utilized, you can still correct the dead load (CAL switch must be
open) without affecting other calibration data/parameters.
