Electronic Digital Vacuum Pressure Gauge , Absolute Pressure Gauge 304SS
Faults and Troubleshooting
The digital pressure gauge is an electromechanical product. During transportation and use, due to environmental disturbances, the improper use of human operations may cause the instrument to not work and display properly. For simple faults, users can eliminate them. Other faults need to be returned to the manufacturer for repair. The following list shows how to eliminate faults.
Symptoms Troubleshooting
No font on screen Replace battery
No change in pressure increase font Remove the battery and wait 30 seconds before reinstalling
The font is non-digital. The LCD is damaged and returned to the factory for repair.
The value is obviously inaccurate. The sensor is damaged and returned to the factory for repair.
Accuracy changes Return to factory for recalibration.
