8. Zero adjustment
7. Zeroing of the dead load (pre-tare zeroing)
Set the decimal point position and the minimum scale increment*1
( 0,001 - 0,002 - 0,005 - 0,01 - 0,02 - 0,05 - 0,1 - 0,2 - 0,5 - 1- 2- 5- 10 - 20 - 50 )
*1Increment = the amount that the scale will increment by as weight is added or removed.
*2Maximum capacity = the maximum weight that can be measured using the scale you are creating.
Set the maximum scale capacity*2(max 999999 )
Zeroing of the deal load (pre-tare zeroing)
This functionality allows to zero the weigh of the scale structure (e.g.: empty silo, empty vessel, etc.) shifting the scale adjustment points.
Examples:
For a 60000kg scale, with 2kg increment:
div.deC = 2
CapaC = 60000
For a 10000 g scale, with 0,1g increment:
div.deC = 0,1
CapaC = 10000,0
For a 3000kg scale, with 0,05kg increment:
div.deC = 0,0 5
CapaC = 3000,00
LC1 mV/V + LC2 mV/V + LC3 mV/V + LC4 mV/V

Span adjustment
It allows to verify signal of the load cell. It should be included into the range 0 to 3 mV/V.
Signal have to be stable and it have to increase by increasing the weight on the scale.
11. Analog output adjustment
Example:
increase a max from 62650
to 62750
1. Connect a multimeter to pin 8 (+) and 9 (-) for the voltage analog output or 10 (+) and 11 (-) for the current analog output.
2. Follow the procedure:
E. Repeat the operation from point “D”
until you obtain the correct value, then
press to store
C. Increase or reduce the value to
optimize the analog output value
F. Save setting (Press Ckey many times
until save? message will appear, then
press to confirm)
D. Press to update the analog
output value
A. Enter the parameter you want to
adjust (a max, a ze, a min) and
set a rough value:
Voltage output
62650 = ~ 10V
12000 = ~ 0V
0 = ~ -2V
Current output
58600 = ~ 20mA
12700 = ~ 4mA
0 = ~ 0mA
B. Press to update the analog

MESSAGE DESCRIPTION SOLUTION
preC. Calibration error First calibrate the zero point, then proceed with the next points.
Err.pn Calibration error
Check the connection of the load cell. Check that the cell
signal is stable, valid and greater than that of the previously ac-
quired point.
Er 11 Calibration error Increase the calibration weight.
Er 12 Calibration error
Check that the signal coming from the cell increases upon the
increasing of the weight loaded on the scale. When acquiring the
calibration points, use the increasing calibration weights.
Er 37 Calibration error Repeat the calibration, checking that the capacity and
division have been correctly set.
Er 39 Instrument not configured Transmitter needs to be configurated.
C.e r. 36 Calibration error Check that the signal coming from the load cell is not negative.
C.e r. 37 Calibration error Check that the signal coming from the load cell is not negative.
Err.m Weight unstable
Check in adC.Mvv parameter that the signal is stable. If the con-
nection of the cells is with 4 wires, check that the sense jumpers
are inserted.

9. Store calibration using the write calibration command (0024 Hex)
40001
1(MSB) 00 Hex
2(LSB) 24 Hex
10. Wait for calibration OK status in register 30116
30116
1(MSB) 2(LSB)
00 Hex 04 Hex Calibration OK
NOTES:
• While write calibration command is in progress, some Modbus reading timeout may happen because of the saving procedure
• To abort the calibration underway use 0026 Hex command in register 40001
