Hammer Head Calibration

dan140465 · 21st July 2006, 00:32

On the classic electronics, they prompt for the O2 %, before calibration, ie a datum point for the electronics to start from, before you calibrate, I was told by my instructor to set this to 98%.

With the hammer head electronics, this is not the case, as there does not seem to be a way to input the O2 %, prior to calibration.

So without a datum point to begin with how can you get the unit calibrated ?

This might seem like an obvious/dumb question, i`ve looked through previous posts but have been un able to get the answer i seek.

Also does anyone know the costs on unit servicing/upgrading.

Many thanks in advance

Danny

The HH only supports the use of 100% o2 for calibration.

I agree with mark, The HH was designed to be calibrated with 100% Oxygen at Sea level, but it can be calibrated with alternate gases if you build the right tools and understand the procedure necessary.. See my article on "accurate po2 calibration"
