System errors:
Code Error Description
71-76 NVRAM CRC error Three areas exist (1,3 & 5) each with a backup (2,4 & 6). Area 1
contains user parameters i.e. calibration data and the backup is write
protected so if this area is restored user calibration etc is LOST.
Error 71 will be reported in response to any read request until either
a calibration is performed or the instrument is rebooted. Areas 3 & 5
are read only so they can be silently restored. Errors 73 & 75
therefore should never be reported, although they exist internally
until they clear themselves. Errors 72,74 & 76 will be reported in
response to any read request and cannot be cleared.
77- 78 TCD curve error In reading curve data from EEPROM the instrument has attempted
to read beyond the ends of the curve.
79 Wrong block no. The serial numbers of the Nitriding Sample Cell stored in areas 1 & 5
(in separate devices) do not match
80 UART missing/error. For debugging only. Since the only interface available is RS232, this
error can never be reported!
81 Reserved For external EEPROM not found.
