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 .
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
5. Save calibration (Press Ckey many
times until save? message will
appear, then press to confirm).

Zeroi Mechanic Tare (pre-tare zeroing)
7© Rice Lake Weighing Systems •All Rights Reserved
7. Zeroi Mechanic 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.
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.
5. Save adjustment (Press Ckey many
times until save? message will
appear, then press to confirm).

14. Programming Errors
MESSAGE DESCRIPTION SOLUTION
preC. Calibration error First calibrate the zero point (zero), then proceed with sample
weight acquisition (span) (section 9).
Err.pn Calibration error Check the connection of the load cell. Verify the load cell signal is
stable, valid and greater than the previously acquired point.
Er 11 Calibration error Increase the calibration weight.
Er 12 Calibration error Check the signal from the load cell increases when weight is
incremented on the scale.
Er 37 Calibration error Repeat calibration and verify capacity and division have been
correctly set.
Er 39 Instrument not configured Transmitter needs to be configurated.
C.e r. 36 Calibration error Verify the signal from the load cell is not negative.
C.e r. 37 Calibration error Verify the signal 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.
