DG03 High Nitrogen Alerts

[Viperz28]

It seems every time I dive I receive High Nitrogen Alerts after a short period of time and I cannot find any information as to what I am seeing and why none of my other DC's show this alert or on my dive buddies DC.

The alarm is based on the setting for the nitrogen bar graph (alarm description pg.7; bar graph description pg.9; setting instructions pg.17 manual) or the max tissue loading bar graph (under configuration/dive computer/Alarm tab if you're using the Hollis PC software). They are the same setting. You can set the alarm to be triggered at any one of the 7 segments of the bar graph (choose 1 of 7 settings).

Hi @Viperz28

I dive an Oceanic VT3, similar to your Hollis DG03. As your high nitrogen alarm is going off at only two bars on the graph, I would imagine that the alarm is set at this point. The nitrogen bar graph alarm is chosen in the Set A group menu, the 4th item. This is on page 17 of your owner's manual.

It looks like you have a choice of setting the alarm anywhere between 1 and 7 segments. My VT3 allows me to set it at 8, when I enter deco.

Hope this solves your problem

Good diving,

Craig

Edit: sorry for redundancy, @AdivingBel was posting at the same time. Good we had the same idea

The computer is so frigging complex and confusing, glad I bought it for only $50

Good deal, better than the DGX cost for a new one, $199

Ok, the value was set to the first bar. Now I a,m going through the menus again, thanks for the help.
