5.4.15 Subsequent Dead Load Correction
If the hopper/platform 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 already utilized by
zero tracking or zero setting, select [Calibration] and press
; this also activates 10-fold increased
resolution of the weight value. Press again to return to the previous state:
Current zero setting: 0.123 kg
If the entire zero-setting range is already utilized, you can still correct the dead load (CAL switch
must be open) without affecting other calibration data/parameters.
To do this, select
-[Calibration]-[Modify] and determine the dead load with [Dead load at]-[by load]
(see Chapter 5.4.9).
5.4.16 Linearization
After selecting -[Calibration]-[New]/[Modify] and after completing calibration, select the
linearization menu with softkey [Linear.]:
by load by mV/V by data Linear. Test
When you press [Linear], the menu shown below appears:
WP A/Calibration/Linearisation
Max at 3000.00 kg 1.000000
Add by mV/V by load
To add a new linearization point, press [Add], fill in the weight value, apply the weight and press [by
load]. Then fill in the corresponding value in mV/V for the weight. After pressing [mV/V], the value
can be entered directly.
Up to 3 linearization points can be determined.
A linearization point can be added with [Add], removed with [Delete] and changed with [Change].
WP A/Calibration/Linearisation
1. Lin. point 750 kg 0.250010
2. Lin. point 1500 kg 0.500020
3. Lin. point 2250 kg 0.750040
Max at 3000.00 kg 1.000000
Add Change Delete by mV/V by load
A linearization point can be selected with
,
changed with [Change] and deleted with [Delete].
