To determine if the digital pressure gauge is working properly, the following steps can be taken for testing and verification:

1. Use a calibrator for testing: Use a specialized device called a calibrator to measure the accuracy of the pressure gauge. The calibrator will generate a certain pressure. By comparing the data displayed by the calibrator with the value displayed on the pressure gauge, if the two match, it indicates that the pressure gauge is working properly.

2.Perform visual inspection: Check the appearance of the pressure gauge for any damage, such as cracks or scratches on the glass casing. At the same time, check whether the display screen is clear and visible, without blurring or wear. In addition, ensure that the pointer can move freely without getting stuck or swaying.

3.Test reading accuracy: Connect the pressure gauge to the object being tested and record the value displayed on the pressure gauge. Then use a testing instrument to measure the pressure at the same point and record the value displayed by the instrument. If there is not much difference between the two, it indicates that the pressure gauge is working properly.

4.Check the connection port: Ensure that the connection port between the pressure gauge and the measured object is not loose or leaking. For digital pressure gauges, it is also necessary to ensure that their display screen has no faults or display errors

5.Check the accuracy of the testing instrument: Use a calibrator or other verification tool to calibrate the testing instrument to ensure its accuracy. If inaccurate instruments are used to test pressure gauges, it may result in incorrect results.
