Re: [IP] 5 unit prime



The higher up above the pump you hold the infuser, the more pressure it
takes to lift the insulin. Try  this, hold the infuser a foot above the
pump, prime until you get the first small drop, if you lift the infuser, you
should see the drop shrink.
Also, if you primed a drop with your arm fully extended up...you will see
more insulin come out as you lower your arm.

I have played with this several times while changing sets...lift my arm and
the drop gets smaller...lower my arm and the drop gets bigger.

The difference may simply be that you are holding the infuser at different
heights when you prime.
