Frequently Asked Questions
Q
What parameters can this gauge monitor simultaneously?
This multi-function gauge supports up to 9 parameters simultaneously, including RPM, Speed, Turbo/Boost Pressure, Water Temperature, Oil Temperature, Oil Pressure, Voltage, Air-Fuel Ratio, and Exhaust Temperature.
Q
How does the alarm system work?
The alarm system monitors key parameters such as Speed, Tachometer, Water Temp, Oil Temp, Oil Pressure, Boost, and Voltage. When any value exceeds the preset threshold, it triggers both an audible buzzer alert and visual warnings via 8 LED indicator lights.
Q
Can the screen brightness be adjusted automatically?
Yes. The gauge offers both manual and automatic brightness adjustment. Manual mode provides three brightness levels, while automatic mode uses an ambient light sensor to adapt the display brightness to the surrounding environment.
Q
Is professional installation required for the warranty to be valid?
Yes. The one-year warranty is valid only when the unit has been installed by a qualified professional. Proof of professional installation is required for all warranty claims. Damage caused by improper installation or human error is not covered.
Q
What are the spare sockets (1, 2, and 11) used for?
Sockets 1, 2, and 11 are designated spare sockets and must not be used for any other purpose or connected to additional accessories. Please leave them unconnected as instructed to avoid any damage to the unit.
Q
Does this gauge support both metric and imperial units?
Yes. The gauge supports both metric and imperial unit systems. For example, speed can be displayed in KM/H or MPH, temperature in °C or °F, and pressure in PSI or BAR, giving users full flexibility based on their regional preferences.
