4.13 Calibration

The calibration mode allows the user to calibrate, check and zero the static and
differential pressure. Additionally, this mode allows the user to set the bias for the
resistance temperature detector (RTD). During the initial calibration, the
parameters shown in Table 4–1 will need to be configured.
