Causes:
1. The calibration weight does not match the set value.
2. If using a PTA configurable adapter, ensure that the output signal leads (SG+ and SG-) have
been installed into the appropriate terminal blocks. Some sensor manufacturers consider
SG+ to be a compression value, while others consider it to be a tension value. If the indicator
is expecting a compression load but it is receiving a tension signal, calibration cannot
continue. Verify that the tension/compression indicator on the home screen properly
corresponds to the load direction, and switch the signal leads, if required.
The entered calibration point is too close to the previous point.
