OPERATING INSTRUCTIONS

• ON/OFF
  Short-press the ” ” key to power on,long-press the ” ” key to power off.

• Backlight
  Short-press the ” ” key to switch the backlight on and off.

• Working modes switching
  Press ” ” key and ” ” key to switch different working modes.

  In the parameter setting mode, you can set the ultimate vacuum, pressure unit, temperature unit, refrigerant type and auto power off function. The corresponding position on the screen will flash when a certain content is selected. Short-press the ” ” key to enter the setting mode, short-press the ” ” key to switch the setting content, press ” ” / ” ” to set the parameters, select and long-press the ”  ” key to save and exit.
  Note: When setting the ultimate vacuum, press the ”  ” key to reset zero.

• Auto power off settin
  By default,the system automatically turns off after 10 minutes of inactivity. Users can set to cancel the auto power off function.

• The setting method is as follows:
  In the parameter setting mode, press the ” ” key to switch to “AUTO ON”, and
  then press the ” ” / ” ” key to switch to “AUTO OFF” to turn off. As shown below:
