How to Use the DG-700 Manometer

Hi! My name is Joshua Lindsey with CFM Building Science Solutions on behalf of Expert Village, we are going to do a duct test in this house. This right here is called a DG-700, is this manometer. Okay so what we are going to do is run this manometer up after I change the settings on it and what this setting says is flow at 25. The reason is that we tested duct work at 25 pascals which again is our way of measuring pressure. All right we are going to change it to say duct blaster. Okay and speaking of which this entire fan and whole assembly that we've hooked up to the return side of our duct work is called a duct blaster.
