PRES Setting Ambient Pressure for Calculations

Syntax: PRES [aaaa.a]<cr>

Turn the internal DIP switch Calibration Enabled/Disabled to position

ON before setting the pressure and return it to position OFF after making

the setting.

Example:

>pres 12

Pressure : 12.0 bara

Example:

29.9213 inHg = 29.9213 × 33.86388 = 1013.25 hPa / mbar

where

aaaa.a = Pressure (bar

)
