Product Overview
The Ah Qidian QD-YS80 Digital Pressure Gauge is a high-quality measuring instrument designed for precise pressure measurement. It features a robust 304 stainless steel sensor core, ensuring high accuracy, corrosion resistance, impact resistance, vibration resistance, and excellent stability even with low temperature drift. Its low power consumption design allows for long-term battery operation without the need for an external power supply, making it easy to install and use. This versatile gauge can measure gage pressure, absolute pressure, and differential pressure across various media including water, liquid, gas, and gas-liquid mixtures.
Setup and Installation
Proper installation is crucial for accurate readings and longevity of the digital pressure gauge. Follow these guidelines:
- Environment: This precise measuring instrument should be used in an area with good ventilation, easy observation, maintenance, and operation. Ensure the environment is non-corrosive.
- Orientation: Digital pressure gauges should be installed vertically for optimal readability and measurement accuracy.
- Sealing: When installing the digital pressure gauge, it is essential to use appropriate sealing accessories such as copper or PTFE gaskets to ensure a leak-free connection.
- Pressure Range Matching: If using with a desktop pressure pump, pay close attention to matching the pressure range of the gauge with the pump's output.
- Tool Usage: When installing and disassembling the gauge, use tools specifically designed for the hexagon of the pressure gauge joint. It is strictly forbidden to twist the gauge head by hand, as this can cause damage.
Operating Instructions
The QD-YS80 Digital Pressure Gauge is designed for simple and intuitive operation. The LCD display provides clear readings and various functions.
- Power ON/OFF: Long press the "ON/OFF" button for 2 seconds or more to turn the instrument on or off.
- Zeroing: When the instrument is not pressurized, and zero drift occurs, press the "ZERO" button 3 times to zero the reading. Important: Do NOT press "ZERO" while the instrument is under pressure.
- Full Range Query and Unit Switching:
- To query the full range, long press the "ZERO" button for 2 seconds or more. The displayed value will be the maximum range of the instrument.
- While in the full range query page, short press the "On/Off" button to cycle through pressure units: MPa → Pa → mmH20 → kPa → Psi → mH20 → Kgf/cm² → MPa.
- To save the selected pressure unit, long press the "Set" button for 2 seconds or more.

Maintenance
Regular maintenance ensures the longevity and accuracy of your digital pressure gauge.
- Battery Replacement:
- When the electricity symbol on the display flickers, it indicates a low battery. Replace the batteries immediately to prevent low brightness, inaccurate measurement, and incorrect readings.
- For 304 stainless steel instruments, rotate the upper cap buckle over 15° and gently open the back cover to install 2 AAA batteries.
- For ABS instruments, locate the protruding buckle cap on the back cover and gently open it to install 2 AAA batteries.
- Cleaning: Use a soft, dry cloth to clean the exterior of the gauge. Avoid using harsh chemicals or abrasive materials that could damage the display or casing.
- Storage: Store the gauge in a dry, clean environment away from extreme temperatures, direct sunlight, and corrosive substances.
Troubleshooting
Here is a list of common issues and their corresponding troubleshooting methods:
| Problem | Solution |
|---|---|
| No numbers on the screen. | Change batteries. |
| Pressure increases but the number remains unchanged. | Remove the battery and wait 10 seconds before reinstalling it. |
| Non-digital numbers or ink leakage, cracks, LCD screen damage. | Factory repair is required. |
| Accuracy changed. | Factory re-calibration is required. |

User Tips
- Always ensure the gauge is powered off before connecting or disconnecting it from a pressure source to prevent accidental readings or damage.
- When performing zero calibration, confirm that there is absolutely no pressure applied to the gauge.
- Keep spare AAA batteries on hand, especially for critical measurements, as low battery can affect accuracy.
- For long-term storage, remove the batteries to prevent leakage and potential damage to the device.
- If you require a specific pressure range or thread size not listed as default, remember that customization options are available.
