vr3 o2 sensor

[mooncat]

gday guy's, i am having a little trouble when analysing my nitrox cylinders with the vr3 using the o2 sensor. I am finding that it is not stabilising and when i finally get it semi stable the analysis is 10% too high! Do you think that the cell maybe stuffed or is this a general vr3 thing?? the cell is 12mths old and has been used maybe 1/2 a dozen times( this being the case everytime)and is in an airtight container when not in use. The software in the vr3 is the current 3.?? version.

I have no idea about the vr3, but o2 cells do go bad, and off the top of my head, one year sounds right, although I think there are some 2 or 3 years cells out there. What you described sounds like it's the sensor going bad.

One way to check would be to see how many millivolts it's putting out and see if this makes sense with what it's rated to put out. For example a 30mv sensor putting out 5mv is probably due for replacement.

thanks, will give it a try

I agree. Especially if you have not kept the sensor in an air tight, mostly O2-free environment, it may be at the end of it's life span after a year. Whether it's been used much or not.

Give them a call or e-mail.

Other than the sensor how do you like the computer? Do you have the color screen?

Please post the results as I am interested in this computer.

Thanks
