
: choice of a weight followed by the analog output: gross (

) or net (

). If the net
function is not active, the analog output varies according to gross weight.
-

: set the weight value for which you wish to obtain the minimum analog output value.
Only set a value different from zero if you wish to limit the analog output range; for
instance: for a full scale value of 10000 kg you require an 4 mA signal at 5000 kg and
20 mA at 10000 kg, in this case, instead of zero, set 5000 kg.
-

: set the weight value for which you wish to obtain the maximum analog output value; it
must correspond to the value set in the PLC program (default: calibration full scale). E.g.: if I am
using a 4÷20 mA output and in the PLC program I wish to have 20 mA = 8000 kg, I will set the
parameter to 8000.
-

: analog output correction to zero: if necessary adjust the analog output, allowing the PLC
to indicate 0. The sign “-“ can be set for the last digit on the left. E.g.: if I use a 4÷20 mA output
and, with the minimum analog setting, the PLC or tester read 4.1 mA, I must set the parameter to
3.9 to obtain 4.0 on the PLC or tester.
-

: correction of analog output to full scale: if necessary permit modification of the analog
output by allowing PLC to indicate the value set in the parameter

. E.g. if I am using a
4÷20 mA output with the analog set to full scale and the PLC or tester reads 19.9 mA, I must set
the parameter to 20.1 to get 20.0 on the PLC or tester.
Minimum and maximum values which can be set for zero and full scale corrections :
ANALOG OUTPUT TYPE Minimum Maximum
0÷10 V -0.150 10.200
0÷5 V -0.150 5.500
±
10 V
-10.300 10.200
±
5 V
-5.500 5.500
0÷20 mA -0.200 22.000
4÷20 mA -0.200 22.000
NOTE: the analog output may also be used in the opposite manner, i.e. the weight setting that
corresponds to the analog zero (

) may be greater than the weight set for the analog full scale
(

). The analog output will increase towards full scale as the weight decreases; the analog
output will decrease as the weight increases.
For example:


= 10000

= 0 analog output 0÷10 V
Weight = 0 kg analog output = 10 V
Weight = 5000 kg analog output = 5 V
Weight =10000 kg analog output = 0 V
