Q. If you saw this (three sensors out of agreement) what would you do? A. When three sensors are out of agreement on the Shearwater Petrel controller, the solenoid will not fire. You will see a message “Voting Logic Failed.” You should bail to open circuit. A diluent flush may confirm which (if any) of the sensors is working properly in the event that you have a long transit out of an overhead environment and are concerned about the volume of open circuit gas available to you. In that case you could theoretically run the unit manually on one working…
Calibration Errors on a Shearwater Petrel Q. I’m trying to calibrate my unit. The HUD shows 1.0 with green and yellow rows of lights. I have fully flushed with oxygen. The handset reads .97, .98 and 1.00 already. The millivolts on the first screen look right and are in range. What is it failing calibration? Looking at the failure screen the millivolts are off the charts, each reading over 200? What’s going on? A. Check your System Settings. Ensure the Calibration O2 is the correct value. After a battery failure, numerous parameters in your computer such as “units” reset. Your…
Mask, fins, rebreather and you are ready to go, right? There are many small items that you might not think about that can ruin a trip in their absence. Power Inquire about the local power supply. As an example, Mexico has the same current as the US, but many wall outlets do not have grounding plugs. You will need to purchase “cheaters” that convert your three-prong plugs to two-prong. Power strips are worth their weight in gold since wall outlets may be few and far between. In Europe, recessed wall plugs may not fit the fancy converter you bought at…
When using a car and boat, your dive destination may be a lot closer to home, but there are still a few special tips to consider. Bring extra bungee cords for boat travel. Many boats are specifically constructed for single tank divers. The benches may be awkward for a rebreather diver. Bring your own method of securing the rebreather to the bench or the floor. Consider the orientation of your rebreather scrubber. If your rebreather is lying on its back, vibrating on a moving boat or in a car for hours, will your particular canister design be subjected to drastic…
