Error description

PASS

Calibration was successful. No Errors found.

Er 1

Signal read by the amplifier is too large when maximum tension is applied.
This is caused by maximum tension being too large. Reduce maximum
tension.

Er 2

Signal read by the amplifier is too small. Too little of the load cell range is
being used, thus the gain is greater than 32:1. Use more of the load cell
range or set maximum tension higher.

Er 3

Roller weight too large. Roller weight exceeds 90% of the load cell rating.
Make roller weight smaller.

Er 4

Calibration tension is greater than Maximum tension. Make Maximum
tension larger than Calibration tension.

Er 5

Maximum tension exceeds the load cell rating. Lower wrap angle, make
roll weight smaller or get higher rated load cells.
