The correct steps for using the pressure gauge calibration table are as follows:

1.Preparation work:

• Check the pipeline to ensure cleanliness, especially when using gas as a pressure medium, the pipeline must not be contaminated. ‌

• Connect the standard pressure gauge calibrator to the "standard instrument" interface. ‌

2. Connect the tested instrument:

• Connect the tested instrument to the calibrator using the provided high-pressure hose.

3.Power on and zero calibration:

• Press the "ON" button to turn on the calibrator, and the LCD display screen will show the measurement status; Press the "OFF" button to turn off the instrument and cut off the power supply.

• Before measurement, press the "zero calibration" button, and the instrument will automatically collect the zero value of the sensor and send it to the processor CPU for processing to ensure that the measured data is the actual pressure value.

4.Unit setting：

• After turning on, the pressure unit of the current instrument will be displayed in the lower right corner of the LCD. Press the "Unit" button to select different units, such as Psi, Bar, mmHg, Kgf/cm2, etc.

5.Perform verification:

• Calibrate the tested instrument according to the national verification regulations.

• You can choose matching software to achieve automatic calibration.

Attention:

• Ensure that there are no gases or impurities present in the pipeline, especially when using liquids as pressure transmission media.

• Regularly inspect and maintain the calibration bench to ensure its proper functioning.
