Instructions for Use
This pressure gauge has three buttons: “ZERO”, “UNIT”, and “Light icon”
1: Press the ZERO button for 5 seconds to reset to zero. However, please do not press the ZERO button randomly for resetting. Only when the gauge fails to return to zero after a long period of time without pressure, can you press the ZERO button for resetting
zero
2: Long press the UNIT button for 5 seconds to turn off/turn on the device. Press the UNIT button once to switch units. To turn on, long press the UNIT button until numbers appear on the display. To turn off, long press the UNIT button again
The numbers on it disappear
3: Press the light icon button to display the backlight, which will automatically turn off after 10 seconds.
Notes:
1: When the pressure gauge is not being tested for a long time, please press and hold the UNIT button for 5 seconds to turn it off, which can extend the battery life. When testing is required, press and hold the UNIT button for 5 seconds again to turn it on
2: When the display on the pressure gauge fluctuates, it indicates that the battery needs to be replaced.
3: During installation and use, be careful not to let the pressure-sensing diaphragm of the pressure gauge collide with hard objects.
