Buttons Operation:
1.Power on/off Button: Short press to turn on or off, long press to select whether to turn off automatically, and press HOLD to select ON or OFF. ON means automatic shutdown is on (automatic shutdown time is about 25 minutes), and OFF means automatic shutdown is off.
 
2.HOLD Button Power on status:Short press is the data holding function. At this time, the "HOLD" symbol will appear on the display, and then short press to cancel the holding function. If there is a base number before measurement, press and hold it for more than 5 seconds, the display of the screen will show “---”, and the instrument is reset to zero.
 
3.UNITS Button Power on status:Unit conversion function. Press this button to cycle between units, Bar,mmHg,Ozin2,Kgcm2,Psi,inH2O,kPa，ftH2O,inHg,cmH2O,Mbar.


4.
DIF Button Power
 on status: Difference value button, the pressure value after pressing the button minus the pressure value before pressing the button.

 5.RFC Button on status: Press the button for a short time to enter the recording mode, and press and hold button for 5 seconds to exit the recording mode. In the recording mode, continue to press the button briefly to view the maximum, minimum and average values recorded in the measurement. Other functions cannot be operated.

6.LIGHT Button on status: Press this button once to turn on the backlight, and press it again to turn off the backlight, or the backlight will turn off automatically after 30 seconds.
