# The system or the analyzer is in the operation mode SXYZ. This mode will be finished.
Then, it will be tried to get the stand-by mode ready for an error free measurement. If
there will be an error in the function SXYZ, the system or the analyzer will try to remove
this error to get the stand-by mode ready for an error free measurement (i.e. FID flame
is not burning, the FID will try to ignite). The operation mode of the system or analyzer is
"stand-by" during these check-ups, even if the device is not ready and error free. That
means, the status STBY will be reported to the read command ASTZ. The test bench
control computer can only realize with the read command ASTF (error status), if the
device is ready for measurements. The device will be ready to measure, if the essential
functions of the current measuring instruction will be error free.
Example:
The system or the analyzer is in the operation mode SXYZ. An error is existing with the
error number n, i.e. FID flame is not burning. The test bench control computer will ask
for the error status:
Test bench control computer sends ASTF Kn
→ System or analyzer will response ASTF x n
Test bench control computer sends STBY. System or analyzer shall accept the stand-by
mode and get ready for an error free measurement:
Test bench control computer sends STBY Kn
→ System or analyzer will response STBY x
The system or analyzer is finishing the operation mode SXYZ. Then, it will try to get the
stand-by mode for an error free measurement. The system or analyzer will check the
conditions and will try to remove the error, i.e. ignition of the FID flame. The test bench
control computer will read the operation mode:
Error is removed (e.g. Flame was ignited):
Test bench control computer sends ASTZ Kn
→ System or analyzer will response ASTZ 0 SREM STBY
or
Error is still existing (e.g. Flame has not been ignited):
Test bench control computer sends ASTZ Kn
→ System or analyzer will response ASTZ x SREM STBY
Test bench control computer sends ASTF Kn
→ System or analyzer will response ASTF x n
The error status byte will be zero and the system or the analyzer will be ready to
measure, if the error is removed i.e. the FID flame is still burning.
If these parameters are not correct, the error status byte will be different from zero. The
test bench control computer will read the operation mode and the error status as long as
the system or the analyzer will be ready to measure. The test bench control computer
will control the maximum time for this reading.
