"Difference is too small" message (during calibration)
reason for the message is that the change in analogue output from the scale
base between zero calibration and the span calibration value is too small.
most likely reason is that the amount of weight placed on the scale for span
calibration is too small – the minimum value should normally be around 50kg or 120
less likely reasons could be:
- The load cell
cable from the scale base junction box to the indicator is disconnected,
cut, or damaged
- Doing a span
calibration without putting weights on to the scale
- Doing the zero
calibration with weights sitting on the scale
- Failed load cell
- Mechanical bind
under the scale preventing the full load being detected by all four load
"Not enough weight" message displayed when trying to calibrate
This message is displayed when the scale Analogue to Digital (A to D) converter doesn't see enough change from zero to the calibration weight value. Normally this is a problem when using only 40 kg for calibration. Things to try: Try using 100 kg ...
"Error Data Nil" message
The "Error Data Nil" message on the passenger panel means that power is applied, but no RS-485 data is received at the passenger panel. The centre two pins of the connector and cable are used for the communications. This issue can be associated with ...
"Bad addr" message on passenger panel
The command from the operator panel has a standardised format that includes an address byte. The message on the passenger panel indicates that the format received is unexpected. The fault could be with the operator panel, load cell cable or the ...
Screen shows ADC 2 error
This is usually a short circuit in the load cell cable, or an internal problem in the trimmer box. If the input signal from the load cells is shorted to the excitation voltage, then the scale will first read "Heavy Bag", then display the message "ADC ...
