Minimum and maximum values which can be set for zero and full scale corrections:
ANALOG OUTPUT TYPE
Minimum
Maximum
0÷10 V
0
10.200
0÷5 V
0
5.500
0÷20 mA
0
22.000
4÷20 mA
3.5
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.
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
TEST
- Input test:
: ensure that for each open input is displayed,  is displayed when the input is closed.
- Output test:
: setting  ensure that the corresponding output opens. Setting  ensure that the
corresponding output closes.
- Millivolt test:
: it displays the response signal of each load cell expressed in mV with three decimals.
COMMUNICATION INTERFACE
- Input test:
close the inputs to be tested and check that INS correctly reports their status.
- Output test:
force the status of the outputs to be tested in CMDOUT and check that OUTS correctly reports
their status.
- Millivolt test:
send command 6137 to CMDR, read the value in R1 and divide it by 10000 to get the mV.
