a very silly question

wannabe · 15th August 2006, 04:22

hello guys, I have a very basic and silly question to ask. Just forgot to ask that during my course.

If I know the mix in my diluent and flush the loop and get the correct reading for the 3 sensors PO2, does it mean that the calibration is correct also? Or can it still go wrong?

Bear with me guys.

Many thanks

A dil flush can verify your calibration. If you know the fraction of O2 in your diluent and multiply by the ata of the current depth you should get a reading close to your expected PO2 if not you're sensors are not giving you good data (for whatever reason)

No silly questions mate.

Thanks Dave, feel more at ease now! Yes I did a diluent flush at 9m knowing the mix is .21 and all 3 sensors showed 0.4 or thereabouts.

Good question Wannabe. The only foolish question is the one unasked.
