PSTAB Setting the pressure stability indicator
PSTAB x <cr>
where:
x = pressure reading (in current unit)
The PSTAB command is used to define the pressure stability indicator
reflecting maximum allowed pressure difference between two
successive averaged measurements. The user has to also define the
FORM command to include the "OK" stability indicator field. The
factory setting for the stability indicator level is 0.5 hPa.

PDMAX Setting the pressure difference limit
PDMAX x <cr>
where:
x = pressure reading
This command is used to define the maximum pressure difference
between the pressure readings from two pressure transducers (P1 and
P2). If the defined value is exceeded, the relevant digits in the ERR
field will change from 0 to 1. More than one ´1´ in the ERR field
indicates that the pressure reading output is not reliable.
For an acceptable measurement crucial conditions are:
- two transducers: P high - P low
≤
Pdmax
The factory setting for Pdmax is 1 hPa.
