Using Serial Line
PRES and XPRES
Command XPRES should be used if the value is changed frequently. Its
value is not retained at reset, and when set to 0, last value set with PRES
is used instead. Use the serial line and do the following:
PRES [aaaa.a]
XPRES [aaaa.a]
where
aaaa.a = Absolute process pressure (hPa)
Example:
>pres
Pressure : 1013.00 hPa ?
>pres 1010
Pressure : 1010.00 hPa

1) psia = psi absolute.
Example:
29.9213 inHg = 29.9213 x 33.86388 = 1013.25 hPa
PFIX
Use the PFIX command to select either P inputted or P measured.
- When PFIX is On, fixed PRES value is used
- When PFIX is Off, measured PRES value is used
