❓ Frequently Asked Questions
QWhat parameters can this gauge display?
AThis multi-function gauge supports 9 display parameters: RPM, Speed, Turbo/Boost, Water Temperature, Oil Temperature, Oil Pressure, Voltage, Air-Fuel Ratio, and Exhaust Temperature. You can switch between them as needed during operation.
QDoes this gauge support both metric and imperial units?
AYes. The gauge fully supports both unit systems. Speed can be shown in KM/H or MPH, temperature in °C or °F, and pressure in PSI or BAR — giving you complete flexibility to match your regional preference.
QHow does the alarm system work?
AWhen any monitored parameter — including Speed, RPM, Water Temp, Oil Temp, Oil Pressure, Boost, or Voltage — exceeds a preset threshold, the built-in buzzer and 8 LED indicator lights activate simultaneously to alert the driver in real time.
QCan the screen brightness be adjusted?
AYes. The gauge offers manual adjustment with three fixed brightness levels, as well as an automatic mode that reads ambient light and adapts sensitivity in real time — ensuring clear visibility in both bright daylight and nighttime driving conditions.
QWhat does the warranty cover, and what is excluded?
AThe gauge comes with a one-year manufacturer warranty covering factory defects under normal usage conditions. Damage resulting from human factors — such as incorrect wiring, water ingress, or physical impact — is not covered. Valid proof of professional installation is required for all warranty claims.
QWhat should I do with the spare sockets (1, 2, and 11)?
ASockets 1, 2, and 11 are reserved spare ports with no assigned function. They must not be connected to any external device or repurposed for other uses. Leaving them unused as instructed helps prevent potential device malfunction or damage.
