At this time, it should automatically start display without any button press.
3. OLED Screen Overview The OLED display not only shows pressure readings but also other useful information. For example, the “AVG” screen indicates that the average of 10 seconds is shown in Figure 3.1. The screen display includes: Screen Name: There are “LIVE” screen for 1 second average reading screen, and “AVG”...

Unit: the readings are in the unit of Pascal by default. Users can change the unit to inches of water, through the app. Figure 3.1...
4. Changing Batteries The manometer uses two AA batteries. Follow these steps to replace the batteries: 1) Unscrew the battery door screw; 2) Open the battery door; 3) Replace two AA batteries; 4) Close the battery door. Make sure the hinge catches; 5) Drive the battery door screw back in while holding the door closed with your thumb.
5. Connecting Sampling Tubing The ports are sized to fit 3 mm ID silicone tubing supplied with the instrument. Push and pull the tubing on and off the port, without twisting. 6. The App The manometer can be connected to an Android app, which allows you to see the results remotely and to graph the results over time.
