If one of the errors above is generated, the power supply must be turned off and
then turned on. If one of these errors is generated again, the power supply must
be delivered to B&K Precision for service.
Calibration Errors
Here are calibration error messages generated by the power supply:
Error 637: Secure code checksum failed
If this error is generated, the power supply must be unsecured using hardware
unsecure procedure. After that, the power supply must be secured. For more
information, see Calibration Overview section.
If the error persists, the power supply must be delivered to B&K Precision for
service.

Error 706: Secure code memory bad
If this error is generated, the power supply must be turned off and then turned
on. If the error persists, the power supply must be delivered to B&K Precision
for service.
