"Accuracy of cells
While the Narked @ 90 cell and the APD16 cell are very stable they have an unfortunate trait in that once the Inspiration scrubber warms up from top to bottom, which is 15 to 20 mins after the start of the dive, the cells read 0.05 bar higher than the actual PO2
i.e. while the cells display 1.30 bar ( the setpoint) – the actual PO2, measured on a calibrated fast response external analyser, is in fact 1.25 bar.
Although undesirable, this trait is repeatable and reliable and so is easily compensated for.. simply by reducing the High Gradient factor slightly.
Typically reducing the GF High by 5 is sufficient: If you use 90 normally – use 85; if you use 85 normally – use 80 etc.".
