Here we first choose the specific analyzer module and then we select at the parameter
"Gastest of specific module" the required gas.
Each of the following types is possible:
• 
SAMPLE-GAS (test mode deactivated)
• 
ZERO-GAS
• 
SPANGAS-1 (spangas for range 1)
• 
SPANGAS-2 (spangas for range 2)
• 
SPANGAS-3 (spangas for range 3)
• 
SPANGAS-4 (spangas for range 4)
With parameter "Timeout for Gastest" we can determine a time after which the activated
gastest switches automatically back onto SAMPLE-GAS.
Is this parameter set to "0" the automatic back switching is not done automatically and
user must break this mode with a "Cancel Calibration"-Command.
