NOTE In case of an error in a PTB220 series barometer, there will be no
pulse output from the barometer despite an external trigger pulse.
This error handling technique ensures that a host system can not
receive erroneous pressure readings from a PTB220 series
barometer.
NOTE If the analog output module is installed the PULSE output mode
cannot be used.
