linearization, to set or clear the preload, and to enter the date of service.

In the numeric menu: The Setup menu for WP1 (WP-1) and the COM1 (COM1) and UniCOM (UNICOM) ports is

extended by the following items for configuring weighing platforms WP1 (WP-1) and WP2 (WP-2):

1-9 Calibration/adjustment functions:

(service mode not required)

displayed. When all weights are loaded, press the „tare“ button to start the adjustment function.
