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].
