304  W    aQ  The amplification drift exceeds half the 
permissible range. 
Monitor the drift. The measured value is 
valid as long as the drift remains below the 
value specified in the measurement data. 
The detector concerned will have to be 
exchanged in the near future. Manually 
calibrate the indicated detector at the zero 
and end point. Permissible range: 50 % of 
the detector sensitivity. As soon as the drift 
exceeds this value, notify Service. 
305  A  S  aQ  The amplification drift exceeds the 
permissible range. 
Exchange the detector concerned. Notify 
Service. Carry out a basic calibration (with 
TCT). 
306  W    aQ  The offset drift between two calibrations 
exceeds the permissible range. 
Manually calibrate the indicated detector at 
the zero point. (This message is generated 
by automatic calibration.) Permissible 
range:15% of the smallest installed 
measuring range; 6% of the smallest 
installed measuring range for 
measurements on plants subject to 
approval pursuant to the 27th and 30th 
Federal Regulation on Immissions 
307  W    aQ  The amplification drift between two 
calibrations exceeds the permissible 
range. 
Manually calibrate the indicated detector at 
the end-point. (This message is generated 
by automatic calibration.) Permissible 
range: 15% of the sensitivity; 6% of the 
sensitivity for measurements on plants 
subject to approval pursuant to the 27th 
and 30th Federal Regulation on 
Immissions 
308  A  S  aQ  A calculation error occurred during 
calculation of the measured value. 
Switch the power supply off and on. Notify 
Service. 
309  W    a  The temperature regulator is defective.  Notify Service. 
310  W    a  The temperature correction has been 
turned off for this component because the 
measured temperature value is invalid. 
Notify Service. 
311  A  S  a  The pressure regulator is defective.  See status message of the pressure 
detector concerned 
312  W    a  The pressure correction has been turned 
off for this component because the 
measured pressure value is invalid. 
Notify Service. 
313  W    a  Cross-sensitivity correction is not possible 
for this component because the correction 
value is invalid. 
Check with TCT. 
314  W    a  Carrier gas correction is not possible for 
this component because the correction 
value is invalid. 
Check with TCT. 
315  W    aL  No new measured values from the 
analog/digital converter. 
Notify Service. 
316  W    a  The measured value exceeds the value 
range of the analog/digital converter. 
Notify Service. 
317  W    a  A calculation error occurred during 
calculation of the measured value. 
Notify Service.
