Refrigerants are harmful to the eyes.2, Please be extremely careful when connecting pipes, there might be a compressed refrigerant pipe. Please stay the pipe end away from the nearby people.General Operation:1.On/OffPress the Power button to turn on/off the gauge.2.Temperature displayIn power-on mode, press and release power button to display temperature.Press it again to display pressure. It will display current pressure after 5 seconds idle (this function is optional).3.BacklightPress and release ZERO/LIGHT to turn on the backlight. It will be auto-off after 6 seconds idle.4.ZeroPress and hold ZERO/LIGHT for 3 seconds to zero. It will display 8.8.8.8 and then 0.000 after 3 seconds. Press and hold the button again for 3 seconds to display current relative pressure.5.Auto-OffPress and hold the power button and ZERO/LIGHT until ON appears, indicating the Auto-Off function is enabled. The gauge will be auto-off after 15 minutes idle, press and hold the two buttons again until OFF appears, the auto-Off function is disabled.
