Calibration Errors
The following errors indicate failures that may occur during a calibration.
Error # Meaning
701 Calibration error; security defeated by hardware jumper
702 Calibration error; calibration memory is secured
703 Calibration error; secure code provided was invalid
704 Calibration error: secure code too long
705 Calibration error; calibration aborted
706 Calibration error: value out of range
707 Calibration error: signal measurement out of range
708 Calibration error: signal frequency out of range
709 Calibration error: no cal for this function or range
710 Calibration error: full scale correction out of range
711 Calibration error: ADC calibration failed
720 Calibration error: DCV offset out of range
721 Calibration error: DCI offset out of range
722 Calibration error: RES offset out of range
726 Calibration error: ACV offset out of range
727 Calibration error: ACI offset out of range
730 Calibration error: precharge DAC convergence failed
731 Calibration error: A/D turnover correction out of range
732 Calibration error: AC flatness calibration failed; amplitude at xxxx Hz
733 Calibration error: AC low frequency convergence failed
734 Calibration error: AC low frequency correction out of range
747 Calibration variable does not exist
748 Cal: mainframe cal memory write failure
In error 732, “xxxx” is the frequency at which the worst AC flatness deviation was
calculated.
