to prioritize the calibration points.Then supply the pressure to the selected point. After CA value is steady, press to
finish the calibration. Once every point is calibrated, the first line shows the character [END], the second line displays the
new lower/higher limit of PV range. (As figure 4-5-8-2)
c. After calibration, press to the interface as figure 4-5-8-1, press to function 9.
