
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 special circumstances, modification is not
suggested.
3. Perform calibration

Click to perform calibration.

Internal pressurization: According to the calibrator's prompt, make the calibrator output pressure to the standard
instrument. Until the pressure becomes stable, click the measured value corresponding to this calibration point, and input
the pressure reading of standard instrument. After confirmation, click to perform calibration of the next point.

External pressurization:
According to the calibrator's prompt, make the standard instrument output pressure to the calibrator. Until the pressure
becomes stable, click to perform calibration of the next point.
Caution: Please adjust the pressure output of standard instrument to be the same as the set value of calibration point of
the calibrator.

If the measured value deviates greatly from the calibration point, it will give a prompt.

After calibration is completed successfully, new calibration data will take effect immediately, and the calibration
date becomes the present system date.
