nothing is too simple once one gets into it

- the dP units are temp sensitive, if not temp controlled you'll need a zero reading at the start and end; use this to 'correct' the dP reading
(I would not suggest re-setting the zero, this is part of the unit's cal)

yes, your procedure is correct
I lay out the crosses flat on a table and connect them with a short piece of tubing, run a dP curve, then cut that tubing in half to connect wbs; then the single connection loss can be deducted from the wb reading at each flow rate

but you need to do this for each tubing size you will be testing with
