vr3 calibration issues

c5vette13 · 8th December 2006, 23:30

Anyone have any suggestions for calibrating the Vr3 to read po2 via and external cell...I have tried 2 different cells both new, but the VR3 will not read anything lower than 30% o2 in ambient air?

Hi Nick,

Have you calibrated the Cell in 100% (.99) Oxygen?

You need to switch the Cal gas (100%) on to perform the Cell calibration and flush with Oxygen to achieve a stable reading.
Remember to switch it off again after you have completed the Calibration Process and return the Vr3 to your dive gas selection.

You could look here for further info;
