Press Power button to turn on/off the gauge.
2. Temperature display
In power-on mode, press and release Power button to display temperature.
Press it again to display pressure. It will display current pressureafter 5 seconds of inactivity (this function is optional).
Press and release ZERO/LIGHT to turn on backlight. It will be auto-off after 6 seconds of inactivity.
Press and hold ZERO/LIGHT for 3 seconds to zero. It will display 18.104.22.168 and then 0.000 after 3 seconds. Press and hold the button again for 3 seconds to display current relative pressure.
Press and hold power button and ZERO/LIGHT until ON appears, indicating the Auto-Off function is enabled. The gauge will be auto-off after 15 minutes of inactivity press and hold the two buttons again until OFF appears the auto-Off function is disabled.
