USING THE DG-1000 WITH THE MINNEAPOLIS BLOWER DOOR
Before the Test
• Install the blower door frame, panel and fan into an exterior doorway. For instructions about how to do this, please see
Chapter 2 of the Minneapolis Blower Door User Manual.
• Prepare the building for the blower door test. For instructions about how to do this, please see
Chapter 3 of the Minneapolis Blower Door Manual.
Tubing Hookup
1. Attach one end of the green tube to the Channel A reference tap. Run the other
end of the tubing outside through one of the holes provided in the lower corner
of the nylon panel and away from the flow of the fan.
2. Attach one end of the red tube to the Channel B input tap. Attach the other end
of the red tube to the pressure tap on the blower door fan.
Note: For help with how to connect the tubing to the DG-1000, please use the
on our website.
Conducting the Test
1. Turn on the DG-1000 gauge by pressing and holding the power button for a few seconds
2. After the Home screen loads, touch Gauge to open the Gauge app
3. Touch the mode area to open the Channel B Settings menu. Select Flow @50. Touch device and then select Model 3 Fan. Touch
the arrow in the upper left of the screen to return to the Gauge app screen.
Note: In this specialized test mode, Channel A measures building pressure while Channel B displays the estimated building
leakage at a test pressure of 50 Pascals (CFM50). The leakage estimate shown on Channel B is determined by mathematically
adjusting the actual air flow from the blower door fan to a test pressure of 50 Pascals, using the real-time Channel A building
pressure reading and a Can’t Reach 50 factor, which can be found in the
on page 9.
