Megalodon Calibration Procedures

Hi!
This might be a stupid question but why analyze with a separate analyzer again?...like I said..I analyze it in the shop or before putting my rig together
The I callibrate according to the Pre-dive checklist....why connect the analyser again "after" the head?
Is this just a effort to save time and cal and meausure everything at the same time?
Am I getting this?

I am guessing but the analyzer is there so that you can be sure that you have only O2 present at the censors.

I know there were quite a few ftalities on the Meg last year(2005), but to my knowledge this is the first one so far in 2006, or am i wrong?

/Jonny

First one that I am aware of..
There have been 7 total.. first one in 2003, 5 in 2005 and 1 this year

Aha....
But if I let the gas flow through for 4 minutes and I have stable readings for the last 2 minutes the head should be saturated with O2,right?

Sounds like it

You analyze the gas at the shop to know what you have in the tank.. now you need to insure the sensors are only surrounded by oxygen, the easiest way to do that is with another meter.. You can also do this by watching your handsets MV readings, the only problem with this is when its really close you migth think its flushed when it still might have some to go..

Hi,
1-i leave the electronic from the canister,
2-check the PO2
3-check O2 tanks with flow meter
4-install calibratation kit (with same flow meter)
5-connect flow meter to an Air tank and check PO2 (usually don't change)
6-Connect flow meter to O2 tank and wait for same PO2 on point 3
7-Leave calibration kit and wait for low PO2

Sorry for my bad english

Regards

Aldo

For Mike:Why this people PM you et don't ask in forum?

Ok...
Thanx for explaining

Seems to me that there are a lot of rebreather divers out their that do not fully understand how to calibrate their units. I have come across this problem with certified inspiration divers who do not know exactly what they are doing during calibration, only selecting 98% every time, not analyzing their tanks not adjusting for altitude (classic handsets) and not understanding what is happening as the unit begins calibration just staring at the handsets with no real idea of what’s happening.

Clearly understanding how to calibrate the unit is essential. This skill needs to be addressed a lot more during entry-level CCR courses.

Maybe certified divers should be asked to attend some kind of update periodically to learn more about the developing world of diving CCR and gain up to date information on the units they dive.

For some RBW is a great tool for learning but not all rebreather divers visit this great forum to continue their education, in my opinion divers skills should be periodically assessed and new standards and procedures reviewed ensuring divers stay up to date with the evolving world of Rebreathers.
