Weighing Functions
5.2.12 DR3 - Automatic zero adjustment
Zero setting the scale can be performed with the "Zero setting" instruction if
required.
The automatic zero adjustment sets the scale to zero without an instruction if it
slowly drifts away from the zero point. Slow drifting is presumed if the conditions of
standard EN45501 have been met.
!
Attention
In non-calibratable operation (no OIML restrictions), a full scale can also indicate
zero after a period of time subject to a slow drift when this function is activated.
Using this function you must prevent an overload of the scale.
5.2.13 DR3 - Tare selection (subtractive, additive)
The scale can be tared using the "Tare" function if required.
When the subtractive tare is activated, the display value is hidden if the gross value
exceeds the weighing range by more than 9e.
In the case of the additive tare, the display value does not need to be hidden until
the net value exceeds the maximum weighing range. For subtractive tare, the
maximum tare weight is limited to 100% of the maximum weighing range; for
additive tare, it is limited to 250%.
The current tare value is deleted when switching between additive and subtractive
tare.
There is no automatic check to ensure the load cell measurement range offers
sufficient reserves when additive tare is activated; the user must ensure this is the
case.
5.2.14 DR3 - Minimum weight for weighing range 1
The weight value can be used for calibratable recording with the numeral step for
measurement range 1 only above the minimum weight. The minimum weight is
defined by an adjustment or a calibration. The minimum weight depends on the
number and type of load cells used.
The value can be set to 0 on non-calibratable scales.
5.2.15 DR3 - Maximum weight for weighing range 1
The weight can be used for calibrating purposes with the numeral step for
measurement range 1 only under the maximum weight. The maximum weight is
defined with the adjustment.
The maximum weight depends on the number and type of load cells used.
