4. Installation
- Select Proper Sealing: Before installing the digital pressure gauge, ensure you select a proper sealing method.
- Medium Compatibility: Verify that the measuring medium (gas, water, oil, pure liquid) is suitable for the instrument material (stainless steel 17-4PH diaphragm, NBR seal ring).
- Thread Connection: The gauge features an external thread (standard) or internal thread (customizable, e.g., G1-4, NPT1-4) for connection. Ensure a secure fit.
The installation thread can be customized to fit various systems. - Avoid Diaphragm Contact:
Caution!
Do not touch the sensitive element diaphragm in any way during installation.
- Proper Handling:
Caution!
Do not install the instrument by rotating the instrument housing. Always use a wrench on the hexagonal fitting to tighten the connection.
5. Operation
5.1 ON/OFF and Backlight
- Short press: Turn on the backlight.
- Long press: Turn the device ON or OFF.
5.2 Zero Clearing
This function allows you to set the current pressure as the zero point for measurement.
- Long press "ZERO/PEAK" button: Use the current pressure as the measurement zero point.
Information!
- The clearing range is within 5% of the full scale.
- If there is a deviation in the display zero point, use the zero clearing function.
- It is recommended to use the Zero clearing function before each use.
5.3 Peak View (Max/Min Value Holder)
This feature allows you to view the maximum and minimum pressure values recorded.
- Short press "ZERO/PEAK" button: Switch between Maximum value and Minimum value.
- Long press "ZERO/PEAK" button: Clears the maximum or minimum value.
5.4 Unit Switching
The gauge supports multiple pressure units for versatility.
- Short press "UNIT" button: Cycle between pressure units (bar, psi, kPa, MPa, kg/cm²).
Information!
After unit switching, the measured value will display the current equivalent pressure.
6. Maintenance
6.1 Battery Replacement
Caution!
Turn off the power supply of the pressure gauge before replacing the battery.
Battery replacement can be performed by the user. The gauge uses 3 x AAA alkaline batteries (4.5V).
Information!
The battery life is dependent on the battery capacity and the operating mode of the instrument. Refer to the Technical Specifications section for details.
6.2 General Maintenance
The digital pressure gauge is generally maintenance-free under normal operation. Any repairs should only be carried out by the manufacturer.
6.3 Recalibration
The instrument can be recalibrated if needed. Please contact your dealer for recalibration services.
7. Troubleshooting and Fault Codes
If the digital pressure gauge displays a fault code, refer to the following table for handling methods:
| Fault Code | Description | Action |
|---|---|---|
| Er-H | Exceeds the upper measurement range. | Check if the measuring range of the pressure gauge is appropriate for the application. |
| Er-S | Pressure sensitive element failure. | Return the unit to the manufacturer for maintenance. |
| Er-D | Data loss. | Return the unit to the manufacturer or customer for calibration. |
| Er-Z | Zero clearing failure. | Refer to section 5.2 (Zero Clearing) of this manual for instructions. |
8. User Tips
- Stable Readings: Ensure stable mounting for consistent and accurate pressure readings.
