5.11.11 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.
The range currently used by zerotrack or zeroset is displayed in the menu
[System information]-[Show HW options]-[WP A]-[Monitor].
Press the key
to switch on increased resolution (10-fold) for the weight value.
If the full zero-setting range is already being utilized, you can still correct the dead load (overwrite protection
must be deactivated, see Chapter 5.1.5) without affecting other calibration data/parameters.
Calibration is then accessed via [Calib]-[Modify] and the dead load is specified with ‘Dead load at’ [by load]
(see Chapter 5.11.7).
Note
If a linearization was executed (see Chapter 5.11.12) the dead load can not be subsequently
corrected! After selection of the line "Dead load at" the following tip is displayed:
"cannot be changed here
while linearization is active"
Only deletion of linearization points deactivates linearization!
