This function can be used to automatically com-
pare the previous and new zero and sensitivity
calibrations. A warning is output if the difference
between the two calibrations is >6 %. The valu-
es can be viewed using identifiers 3 and 4. The
warning LED is cancelled when function 96 is
called, and the status signal at plug X2 is set to
"No warning" again.
Identifier 1 switches off the device in a controlled
manner. No sample gas is left in the analyzer.
The hydrogen and sample gas supplies are in-
terrupted. Heaters are switched off. Combustion
air is supplied for a further 30 seconds. Small
quantities of combustion air may reach the pro-
cess during this time.
The device startup is initiated using identifier 0.
