parameter settings / changings are limited to be done by authorized
personnel only. Do not attempt to change any of the built-in parameters.
Contact your dealer for installation and technical assistance.

1.3 Warm up time

The higher the setup resolution of the scale, the longer the warm up

period for all applications.
b.
This warm up period is needed to energy all components to reach a
stable status.
c.
The internal count value is deemed stable when the internal AD
count varies less than 3 counts within 2 seconds.

internal AD count value of a not yet fully energized PCB will go up
continuously.
