Name & Function of Each Part
Display Screen: Shows pressure in bar and battery level with a battery icon.
Touch-Key Area: The entire front area is touch-sensitive for operation.
Magnetic Charging Connector: Used for connecting the USB charging cable.
Snubber: Protects pressure sensors and gauges against pressure surges. If loose, use a flat-blade screwdriver to tighten it.
Vent Hole: Explosion-proof design; DO NOT block this hole.
Safety Precautions
❗ General Safety: To ensure operator safety, use this instrument in conformance with the directions and specifications given in this User's Manual.
❗ Warming (Degassing): Before installation, degas your air rifle. Ensure the airgun is unloaded, uncocked, set to SAFE, and pointed in a safe direction.
❗ Important Notes: Using Pom/PTFE/Rubber gaskets could potentially block the air inlet due to over-tightening, which may cause the gauge to read ZERO. Please ensure the air inlet remains clear.
Installation
- Loosen and remove the original gauge from your air rifle. Keep the original seal component if possible.
- If the original seal is used, DO NOT use the Sekhmet seal again. If the original seal is lost or damaged, use one of the two types of seal components provided in the Sekhmet box.
- If Sekhmet seals are used, ensure original seals are thoroughly removed and clean the threads before installation.
- Sealing at the TOP of the thread: use a Dowty seal.
- Sealing at the END of the thread: use PTFE and rubber gaskets.
- After aligning the gauge with the threaded fitting, rotate it to the end. Apply sufficient force to ensure the gauge is fully seated against the seal.
- Use a wrench on the gauge's hex face to turn it. Avoid compressing the panel. DO NOT overtighten the gauge, as this may cause scratches or damage to the surface or panel.
Operation
The pressure gauge features a single touch button with three interactive states:
Power ON: A short touch activates the gauge. The upper left corner displays the barometric pressure reading in real-time (unit: bar).
Battery Indicator: While the screen is on, long touch the area (less than 5 seconds) to switch from pressure display to battery display. The battery symbol in the upper right corner indicates the current battery range (100%, 60%, 20%, 5%, and Lo 5 levels). Release the button to return to the pressure display. Holding for more than 5 seconds triggers a shutdown.
Power OFF: Long touch the area for more than 5 seconds to shut down the gauge.
Auto Power Off: The gauge automatically turns off after 1 minute of inactivity.
Charging Instructions
When the gauge is turned on and the magnetic charging port is connected to the USB charging cable, the display automatically switches to show the current battery level.
The screen turns off after 1 minute. It is recommended to continue charging for an additional 15 minutes after the battery level reaches 100% to ensure a full charge.
When the gauge is turned off, the screen will not wake up automatically upon connecting the USB cable. Short touch the gauge to wake it up and check charging status.
Note: A full charge (0% to 100%) takes approximately 60 minutes.
Battery Level Indicators:
- 100%-60% actual battery level: Display shows 100.
- 60%-20% actual battery level: Display shows 60.
- 20%-5% actual battery level: Display shows 20.
- Below 5% actual battery level: Battery icon and display show '5' blink three times, reminding you to charge.
- Approaching 0% actual battery level: Battery icon and 'Lo' blink three times, and the gauge automatically turns off. Charge promptly.

Frequently Asked Questions (FAQ)
Leakage
If the pressure gauge loses more than 10 bar of pressure within 12 hours in a constant temperature state after installation, check the sealing ring installation. If installation is confirmed correct and no leakage point is found, you can use a balloon to wrap the gauge to observe expansion. Note: The gauge is waterproof, not water-resistant. Do NOT immerse it in water for bubble observation.
Unable to Turn On
Upon first receiving the gauge, charge it for 1 hour. If it still does not turn on after 2 hours of charging, contact Sekhmet customer service or your dealer. Do NOT attempt to open the pressure gauge panel yourself, as this can be dangerous.
