Alarm Settings
The DV-40S has alarming capabilities which can be set to alert when a certain vacuum is reached, and also when
a specific rise in vacuum needs to be detected. The latter is useful when a leak or rise test is being conducted
to indicate the presence of moisture or a leak in HVAC systems.
Set Alarm
1. Tap the JB MAIN MENU in the upper left corner.
2. Select ALARM to access Alarming Menu with
different variables the user can select including
values at which the app will alarm, what type of
sound it will use to alarm, and if the user would
like the smart device to vibrate.
Once options are selected and saved, values will
be stored until they are changed.
Activate Alarm
1. Select the check box on the main screen for either
TARGET ALARM (on the way down) or LEAK ALARM
(on the way up).
2. Once the alarm sounds it can be turned off by
deselecting the check box.
