Available Devices 

Upon opening the app, a list of available devices 
will appear. If there are no P51-870 TITAN® or 
YJACK

 devices turned on and within range, no 

devices will be listed, but as these devices are 
powered on, they will populate on this screen. 
Each device that appears on the list of available 
devices includes some basic information about 
the device. This includes the device serial 
number/Bluetooth® ID, the battery level, and 
any readings that the device is broadcasting. 
Keep in mind that the YJACK PATH

 can be 

utilized to repeat the readings from any P51-870 
TITAN® or YJACK

 device, improving the 

connection range. If a device moves out of range 
or is turned off, it will display on the available devices screen with a red banner. If this occurs make sure 
the device is turned on and moved back within range, possibly by relocating the YJACK PATH

 device. 

General Settings 

Before starting any system readings session with 
the YJACK VIEW

 app, make sure the app 

settings are configured to your preferences. 
Press on the three-dot icon in the upper right 
corner of the screen. A list of configurable 
settings will appear including General Settings, 
Create Datalog, Change Refrigerant, and Change 

Elevation. First, access the “General Settings.”

 

This screen will allow you to set your preferred 
units of measurement for pressure, temperature, 
vacuum, and elevation. You can also turn on and 
off sound notifications and the screen lock 
functions. Once the proper settings have been 

selected, press “Save.”

 If you plan to start a Pressure/Temperature Session, 

again tap the three-

dot icon and select “Change Refrigerant.”

 The list of 

over 126 selectable refrigerants will appear. Next to each refrigerant name, 
there is an outline of a star. Pressing on the star icon will turn the star solid 
yellow and classify that refrigerant as a favorite. Favorite refrigerants will 
always appear at the top of the refrigerant selection screen for easy access. 
To remove a refrigerant from the list of favorites, simply press on the solid 
yellow star next to the desired refrigerant and it will instantly be removed 
from the list of favorites. Once the favorites have been configured as 
desired, and the proper refrigerant has been selected, press Save. The final 
app configuration setting is to set the elevation where the service is being 
performed. Press on the three-

dot icon once again and select “Change
