3.3.1.2 Pressure Calibration
1. Cancel zeroing
Cancel the recorded zero data.
2. Multi-point calibration a. Connection
Connect the calibrator with external pressure source and reference pressure standard. b.
Perform calibration
◆ Click on to perform calibration.
◆ Connect the calibrator with external pressure source.
◆ After the pressure is stabilized, click on to go to next point;
◆ Adjust the gauge output value to the same as the setpoint being calibrated;
◆ If the measured value has big difference with the calibration point, there will be notice by RED;
◆ If the calibration point has big difference with the measured value, there will be a notice, but it does not influence taking effect.

◆ New calibration data takes effect immediately. The calibration date will be changed to the current system date. c.
Restore the factory calibration data
Click on to restore the factory calibration data.
3.3.1.3 Barometric Calibration
The calibrator provides single point or dual point calibration to the internal barometric module. Before performing the barometric calibration, remove the back cover and connect the air line to 4mm connector, as shown in the Figure 11.

1. Single point calibration
Input the external barometric standard to standard pressure value, confirm and click on SAVE to finish calibration.
2. Dual point calibration a.
Connection
Connect the calibrator with external pressure source and provide greater standard of pressure. b. Perform calibration
◆ Click on to perform calibration.
◆ Input the external pressure according to the calibrator’s notice. After the pressure is stabilized, click on to go to next point;
◆ If the measured value has a big difference with the standard value, there will be notice by RED, the result cannot be saved now;
◆ If the calibration point has a big difference with the measured value, there will be a notice, but it does not influence taking effect.
◆ New calibration data takes effect immediately. The calibration date will be changed to the current system date. c. Restore the factory calibration data
Click on to restore the factory calibration data.
