VBD is right, they will settle over time, especially in doubles. I have gotten different readings out of each outlet on my doubles, but let them sit over night and they were right on the mix I was aiming for.

I can handle it that way.verybaddiver:anyways, whatever the dynamics(maybe heat etc) ive known the % changing
I believe if you run the numbers you'd find the amount of diffusion through the manifold to be insufficient to allow significant mixing overnight, which would support the statement that the initial mixing was sufficient.Jimmer:VBD is right, they will settle over time, especially in doubles.

I'm in over my head there. I haven't read up on the temperature dependence of oxygen sensors (or the "patented temperature compensation circuitry" involved). I'd have to study more to be able to discuss logically.Jimmer:Temperature could affect the sensor I suppose, but if I just calibrated it with air, turned around and checked an nitrox tank, there would be no issue, as the sensor was calibrated in the same temperature and conditions.
IIRC, desoldering one resistor and replacing it with the leads to the calibration knob's variable resistor is about all the soldering that's been mentioned.Ice9:Any soldering required to build the El Cheapo II?
