C n Listing transducer coefficients
C n
where n = number of the pressure transducer (1, 2 or 3)
The C n command is used to list all internal coefficients of a
transducer. These coefficients are for factory use only and they cannot
be changed by the user. For transducer P1, the listing looks as follows:

PTEST Testing pulse output mode
PTEST
The PTEST command is used to test the operation of pulse output
mode.
The PTEST command outputs the pressure reading or some other user
defined pressure reading in the form of a pulse output. The pulses
come out soon after the PTEST command is given to the barometer.
