2.2 Transmitter’s functions

Therefore, it is not a traditional weighing instrument, since Gross, Net and Tare management functions are not
available.
Only ZERO corrections can be executed (through external inputs) with the purpose to recover zero derivatives or
deviationsrelativetotheweighingsystem.
The onboard relays are managed as alarm relays, therefore they
are always kept energized and are de‐energized in
caseofalarm.
