5. Maximum Scale Capacity, Increment and Decimal Point Settings
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 ).
Set the maximum scale capacity*2(max 999999 ).
Examples:
6. Theoretical Calibration
Set the total load cells capacity (up to 999999).
Set the load cells sensitivity (up to 999999).
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
(section 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 .
5. Save calibration (Press Ckey many
times until save? message will
appear, then press to confirm).
For a 60000 lb scale, with 2 lb
increment:
div.deC = 2
CapaC = 60000
For a 10000 g scale, with 0.1 g increment:
div.deC = 0,1
CapaC = 10000,0
For a 3000 lb scale, with 0.05 lb
increment:
div.deC = 0,05
CapaC = 3000,00

7. Zero Mechanical Tare (pre-tare zeroing)
Zeroing of the pre-tare (or mechanical tare).
This functionality allows to zero the weigh of the scale structure (e.g. empty silo, conveyor, etc.) without changing the calibration in
memory.
8. Calibration with Sample Weight
Zero point acquisition.
1. Unload the scale. 2. Enter the zero step to adjust the
zero point.
5. Save adjustment (Press Ckey many
times until save? message will
appear, then press to confirm).
Sample weight acquisition.
3. Load the scale with span weight.
4. Enter the span step, type the span
weight value and press to adjust.
9. Load Cell Diagnostics (µV/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.
