HELP with VR£

diveuk · 19th April 2007, 19:17

I am trying to calibrate my VR£ to use an external O2 sensor.

All I can get is a reading of 326.4, what am I doing wrong, I am calibrating in ambient air so the reading should be 21.

can someone please help?

More than likley you have not set the calibration gas up corectly. You have to go to 21% on the gas list switch to 21% and save it as the calibration gas before you calibrate.

Mind you i only ever calibrated it in 100% ?? but this should work.

Hi Diveuk,

As Mark did mention it is better to Calibrate using 100% Oxygen.

You do have to turn on the .99 gas and select it as the Cal gas and then turn it off again after calibrating but at least you will know your sensor can indeed read higher Oxygen readings than 21%

Regards

Thanks Barry, will calibrate with 100% O2 tomorrow or is that today
