5.5.6 Analogue output adjustment
Theadjustmentfunctionsoftheanalogueoutputarethesameforoutputundervoltageandundercurrent.

Theadjustmentoftheanalogueoutputforesees3steps:
1. Settingoftheanaloguescale(FULLSCALED/A)
2. Zeroalignment(ZEROADJUSTMENTD/A)
3. Fullscalealignment(SPANADJUSTMENTD/A)

The
firststepdefinestowhichweightvalue,themaximumvalueoftheanalogueoutputmustcorrespond.
For example,the weighing full scale could be 5000,but themaximum value of the analogue output couldbe set to
3000.
Thisway,forweightvaluesfrom0 to 3000,theanalogueoutput
willrangefrom0 to10V(orfrom 4to20mA);for
higher values,the output will remain set tothe maximum value. Similarly, for negative weight values, the analogue
outputwillremainsettotheminimumvalue.
Thesecondphaseconsistsinaligningtheanalogueoutputsothat
zero(minimumpossiblevalue)ise xactlyat0Vorat
4mA.
Thethirdphaseconsistsinaligningtheanalogueoutputsothatthespan(maximumpossiblevalue)isexactlyat10V
orat20mA.

The ajustment procedure must be viewed on the receiving system of the
transmitted analogue signal. Otherwise, the signal drops due to cables are not
takeninconsideration.
