Scale parameters and functions
8.3 DR 3 calibration parameters
8.3.11
Zero by power-on when tare ≠ 0
The scales can automatically be set to zero when the supply voltage is switched on. If the
Zero by power-on (Page 69) function is enabled, this still does not specify whether zero by
power-on is also to be performed if the tare weight in the tare memory is not equal to zero.
If the "Zero by power-on activated for tared scales" parameter is set, the tare weight is also
be cleared upon zero by power-on; if the parameter is not set, the scales are not set to zero.
8.3.12
Automatic zero adjustment
If necessary, the scales can be set semi-automatically to zero by the user by means of the
"Zeroing" command.
The automatic adjustment sets the scale to zero without a further command in the event of
slow zero drifting. Slow drift is assumed if the OIML R76 criteria for this are met.
Note
If the scales are not being used in legal trade operation (no OIML restrictions) and this
function is enabled, the scales may eventually read zero after a slow drift even if they are
fully loaded. The function can, however, be limited by setting a maximum and minimum
weight for zeroing.
8.3.13
Subtractive / additive tare device
If necessary, the scales can be tared using the Tare" command.
The display value is hidden when a subtractive tare is enabled if the gross value exceeds the
maximum weighing range by more than 9e.
When an additive tare is enabled, the display value is not hidden until the net weight
exceeds the maximum weighing range. The maximum subtractive tare is 100 % and the
maximum additive tare 250 % of the maximum weighing range.
The current tare value is deleted if you switch between additive and subtractive taring.
NOTICE
There is no automatic evaluation of whether there is sufficient load cell measuring range
capacity for an additive tare.
