4.4.5 Pressure calibration
1. Connection
Calibration of the internal pressure module can select internal pressurization or external
pressurization mode.
When the internal pressurization mode is selected, please connect the pressure outlet of calibrator
to the standard pressure instrument.
When the external pressurization mode is selected, please connect the calibrator to the pressure
generation of the standard.
During calibration of the external pressure module, if the calibrated pressure module is covered by
the pressure supply range of internal pressure source, you can select internal or external
pressurization. If it is not covered, you can only select external pressurization.
2. Set the calibration points
Calibrate the internal pressure module of calibrator through 3 points.
Default calibration points are the lower limit, zero point and upper limit of the internal pressure
module.
Calibrate the external pressure module of calibrator through 2 points.
Default calibration points are the lower limit and upper limit of the external pressure module.
The calibration points can be modified. Please ensure that the input set values of calibration points
are within the range of internal pressure module, and point 1＜point 2＜point 3. Except under
