Suggested two-point calibration adjustment points
Calibration points are nominal pressures to allow for slight differences due to primary standard
weights and actual corrected pressure calculations.
- Ps: two point cal points = 1st point is 1128mbar (FS) followed by 92mbar (suggest to be done in this
order).
- Pt: two point cal points = 1st point 92mbar followed by 1997mbar (FS) (suggest to be done in this
order).
