The calibration routine requires a minimum of two pressures within the
operating extremes (maximum of six pressures). The instrument
software calculates an offset and gain correction to be applied to all
subsequent readings using a statistical best straight line method.
For single point calibration, the gain factor is set to unity.
Notes
1
For the pressure sensor to rapidly respond to the applied pressure,
disable the filter by sending the filter command F, 0,0<CR>.
2
Before sending the ‘C’ command set the instrument to operate in the
pressure measurement units required for calibration. i.e. U, 0<CR>
selects mbar. Always use the same units when entering applied
pressures.
Command:
C, PIN
