ELSA EEBD testing (dummy,N2,Nitrogen).

[sm1the]

ELSA EEBD test.
I tested the Elsa EEBD by donning on styrofoam dummy with partial shoulders.
I leak tested regulator/cylinder valve,regulator outlet,dual barb extended hose first with Snoop.
I chose Snoop because apparently its more non-toxic than others and rated for most systems(Ai told me this so not sure!).

Initially I placed an CY-12c O2 analyzer inside the hood,turned on gas at 25lpm.
It was taking a long time for O2 to drop.
I realised this was due to the external probe on analyser creating an opening at the neck (?).
I replaced the CY-12C with another analyser - Toptes guard-756.
Turned on gas at 25lpm.
It dropped to 0.6% at 2min30sec.
I stopped gas at 0.6% because I realised the hood was already probably at 0 but the meter only drops at a certain speed(?).
It dropped to 0% second later(without gas flow).

So could I have achieved 0% O2 much sooner?.

With no gas flow to hood-

• 3mins 0%
• 11mins 0.3%
• 13 mins 0.5%
• 15 min 0.6%

I stopped test at 15 mins(0.6% O2) ,I figured this result is good.
If you dont agree please let me know?
If there is something I missed pls let me know.

I keep thinking I missed things.
I want to test the exhaust valve but I dont know how.

can you list any equipment or setup details . for example how you connected a nitrogen? tank the the ELSA EEBD hood ?

Connections etc , I figured out from the different EEBD threads.
Kind of useless repeating those again as they have already been posted better than I could.
Maybe the brand names of a few items differ in different setups.
