In Order To Obtain Accurate Static Pressure Readings
The Static pressure Pickup Probe Should Be Mounted
Per The Following Recommendations:
1.)The Probe Should Be Mounted In a Straight Section
Of Ductwork Approx. 2/3 The Length Of the Supply Duct,
Downstream Of The HVAC Unit.
2.)The Probe Should Not Be Mounted Less Than 3 Duct
