21 Error messages
21.1 Internal error messages
Display: Lxx
Internal errors arise when recording and processing measured values in the entire
measurement route from the sensor to storing in memory or on the display.
00 – Measured value is ok
01 – AD conversion faulty
0
2 – Communication error
03 – Over/underflow
05 – Wire break
06 – Sensor type dependent
0
7 – Expansion card not available
21.2 External error messages
Display: Sxx
External errors occur in "intelligent sensors" and are sent to the OTT netDL.
