On-site display error messages
If the device detects a defect in the on-site display during initialization, the following error messages
can be displayed:
742 (A742)
Alarm
B
Failure (F)
B>Sensor connection error
(upload)
– Electromagnetic effects are
greater than specifications in the
technical data.
See Technical
Information TI00382P (Deltabar
S), TI00383P (Cerabar S) or
TI00416P (Deltapilot S). This
message normally only appears
briefly.
– Wait a few minutes.
– Perform reset (Code 7864) and
carry out calibration again.
