Thank you for your replies,
I am selecting the hightest occlusion setting on the Baxter pumps (Maximum) and testing at a 10ml/hr rate.
The Metron Infusion Pump Tester and the IDA-1 are (I believe)pressure gauges and I have no reason to doubt the accuracy of both units.
They are also used for other manufacturer's pumps and return expected results within specs.
Do my test requirements and settings seem acceptable.
