Set the maximum scale capacity*2(max 999999 ).
Examples:
7. Theoretical calibration
Set the total load cells capacity (up to 999999).
Set the load cells sensitivity (up to 999999).

Insert in Cel.sen parameter, the load cells sensitivity
sum value:
For each scale to calibrate, insert in Cel.sen parameter the
average sensitivity value of the load cells:
Dead load weight (from -9999.9 to 99999.9).
*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.
1. Set div.deC and CapaC
(ch. 4).
2. Set in Cel.Cap the total load cells
capacity (sum of the nominal load cell
capacities).
3. Set in Cel.sen the theoretical signal
value of the load cells.
4. Enter in dead.ld step. The display
shows the theoretical dead load
value. Modify the value and/or confirm
with .

3. Load the scale with span weight.
4. Enter the span step, type the span
weight value and press to adjust.
10. Diagnostic of the load cell V/V
It allows to verify signal of each channel. It must 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.

MESSAGE DESCRIPTION SOLUTION
preC. Calibration error First calibrate the zero point (zero), then proceed with the
sample weight acquisition (span) (ch. 9).
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
acquired 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.
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.mo Weight unstable
Check in adC.v parameter that the signal is stable.
If the connection of the cells is with 4 wires, check that the sense
jumpers are inserted.
adC.err A/D converter error Converter failure. Reboot the instrument.
Cel.err Global load cell error Signal anomaly: check the load cells connection.
Er.Cel.1

Er.Cel.4
Load cell error Signal anomaly: check the indicated load cell connection.
15. Broken load cell exclusion (for dependent channel systems)
No channel excluded.
Channel 1 excluded.
Channel 2 excluded.
Channel 3 excluded.
Channel 4 excluded.
If a load cell is broken, it’s possible to temporarely exclude the channel where it is connected and continue to weigh, pending
replacement.
WARNING: this operation reduces the accuracy of the weighing system. We recommend use for liquid weighing or in applications
where the load is evenly distributed.
Visible only in DEP.Ch mode.
