- : it selects the analog output type (4÷20 mA, 0÷20 mA, 0÷10 V, 0÷5 V, ±10 V, ±5 V;

default: 4÷20 mA).

for the output ±10 V and ±5 V the soldered jumper SW1 must be closed:

▫ on the analogue-output board find SW jumper, located on the solder side in the

middle.

▫ close the jumper short circuiting the bays, it is recommended that a small piece of copper

wire without insulation or a leg wire be used to facilitate the operation .

- : 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:

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.
