Thanks for the reply, usually the reading is only 1 or 2. Hmm have seen it in dogs etc where dead space is minimal and seen the same reading in different circuits. I will have a look to see ref condensation in the line. But will take your advice and not worry too much since it’s a low reading :) thanks

It could be down to a number of things, most commonly I think would be condensation in the sampling line. Excessive dead space will cuase this too, as would a small leak in the circuit. Other reasons could include the machine itself - calibration / low sampling rate. How much are we talking about..? for readings of 1 or 2, I wouldn't worry.
