I am I right in thinking that if I have atmospheric pressure of 1010mBAR and a cylinder of 100% I should get a displayed value of 1.01 on the handset?
Then if it's higher I need to adjust my O2% down in the calibration sequence and lower tweak it up? did I get those two the right way round?
Yes thats true.. The inspiration cal% is really a fudged value not what the oxygen has been analyzed at.. I find on most rigs 1% less than the actual value usually gives the right outcome.. When it takes a lower number I find its that the IP on the Oxygen reg is a bit high..
just getting the number to what you expect is important, but make sure if you put 1010 for the atmpospheric pressure its really 1010.. for example in the caribean on a normally sunny day the average pressure is usually around 1020-1030 mbar depending on the location.. while near the poles it averages closer to 1000mbar..
