Troubleshooting
W A R N I N G
Multiple hazards. Do not disassemble the instrument for maintenance or service.
If the internal components must be cleaned or repaired, contact the manufacturer.
Error and status indicators
Error and status words follow the same standard definition for all sc
probes and controllers.
Table 3 lists bit position and error messages.
and status messages.
A bit value of zero shows the error or status condition that is not true.
A bit value of 1 shows the error or status condition that is true. For
example, if Bit 0 has the value of 1, an error has occurred during the last
calibration.
