: # 101
0x0F BAD Device Failure Constant Gain Error
Amplifier Cause:
Gain deviation compared to reference gain is
greater than 2%.
Remedy:
Replace the amplifier board

121 S: A/C COMPATIB.
!: # 121 0x0F BAD Device Failure Constant Amplifier and I/O
board only partially
compatible Cause:
Due to different software versions, I/O board and
amplifier board are only partially compatible
(possibly restricted functionality).
!
Note!
– The indication on the display as notice message
appears only for 30 seconds (with listing in
"Previous system condition" function).
– This condition can occur if only one electronics
board has been exchanged; the extended
software functionality is not available. The
previously existing software functionality is still
working and the measurement possible.
Remedy:
Module with lower software version must either be
updated by FieldCare using the required
(recommended) software version, or the module
must be replaced

Error in DAT / no communication
205 S: LOAD T-DAT
!: # 205 0x0F BAD Device Failure Constant Save to T-DAT
failed Cause:
Data backup (downloading) to T–DAT failed, or
error when accessing (uploading) the calibration
values stored in the T–DAT.
Remedy:
1. Check whether the T-DAT is correctly plugged
into the amplifier board.
2. Replace the T-DAT if it is defective.

Page 111 ff.
Before replacing the DAT, check that the new,
replacement DAT is compatible with the
measuring electronics.
Check the:
– Spare part set number
– Hardware revision code
3. Replace measuring electronics boards if
necessary
