White squares in the table are the most commonly used Modes and are set as defaults on your gauge.
Grey settings are turned off by default so are inactive until they are turned back on. Your gauge may
be set up differently when you receive it. Air Changes at 50Pa, which is commonly called ACH50 or n50
is used with Blower Doors to test house leakage. “CFM/100 sq ft” is commonly used when testing
ducts to International Energy Conservation Codes (IECC) in most US States.
The gauge supports a number of calculations which can simplify the testing procedure. Some of these
may be useful for specific testing needs. Use Mode Setup to customize the gauge to enable display of
only the specific results that will be used regularly. The configuration is permanently saved, but can be
changed at any time and the new configuration will be permanently saved. Once configured, pressing
the
[Mode] key on the gauge will cycle through only those Modes that are enabled in the “Mode Setup”
menu.
To configure Modes:
1. Press [Setup] to access the “Setup” menu.
2. Press [  ] or [  ] to select "Mode Setup" in the list. Press [Enter].
3. Press [

] or [

] to select a Mode. Press [

] or [

] to select the units associated with
each mode. Select 'off' to disable that mode on the Main Screen.
4. Some modes have an associated “@ Pressure”. To change it, press [  ] or [  ] to highlight
the associated "@ Pressure", and press [Enter]. Input the new value using the number keys
on the keypad, and press [Enter] again.
