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.
