I.S.D. Motor Tracking

Record the static pressure with a manometer. Measure the return and the supply separately and then add together to get the total static. Forget the + and – and just add the numbers together. Example +.5 measured in the supply and -.3 measured in the return = .8 in wc Total static. Reminder this is a Blower, not a sucker. DO NOT worry about entering the + or the – or the decimal point(.), just enter the number displayed on your manometer.
