Trying to use the SynchPro, but I cannot calibrate the damn thing.
I have the restrictors in the right place and backed out the adjustment screws to give max vacuum range (i.e., lowest possible position in the tube). The instructions say this will allow best calibration, allowing me to raise the fluid levels to a baseline.
But it doesn't.
Instead, the fluid shoots up the tubes leaving them at the top of the gauge or off the chart altogether.
Am I just out the $100, or is there another variable that will help me get this thing to work? I may need to add some of the special toilet-water to try again, but want to see if that is even worth trying before I spend good money after bad.
TIA
