I may be the only one stupid enough to have done this, but are you aware that you have to have boom on in order for the pressure to increase or decrease. If you don't want boom spraying while testing, shut sections off and turn main switch on. Like I said, you probably know this, but I thought I had a problem till I figured this out.
