Nitrox Is it customary to reanalyze it at the dive boat?

As a side note, I knew an instructor who taught the students to test the analyzer by testing a tank of air. How else do you know if the analyzer is functioning correctly??

This is a trick question, right?
I calibrate mine before every use by removing the cap from the sensor and waiving it around in the ambient air.

Ideally, additional checks on 100% O2 and 100% Helium are a nice check on the condition of your sensor.

Rich, this was back around '94-'96 and I do not remember the analyzer. This was down in Florida. I remember the guy having me check an air cylinder to verify that the analyzer was ok.

Always check your own mix. Don't take someone's word for it. You don't want to be another statistic.

Would you trust your spouse if they had the same level training as you???

Absolutely not.
Rule #1 - Every diver is responsible for their own buoyancy at all times.
Rule #2 - Every diver is responsible for the contents of his own cylinder at all times.

That sorta depends... Have the two of you been having a good week? Have you made any changes to your life insurance policy lately?

If the dive is long or deep enough for nitrox to make a difference, I analyze EVERY tank... air or nitrox... immediately after putting my reg on it.

don't you mean before? or do you analyse the mix through your reg or something? just curious...

If the dive is less than 40ft, I don't worry about it and dive it as air.

agreed.

Some analyzers connect to BC inflator hose

FWIW, we keep a tank of air next to the analyzer for calibration.

One slight additional benefit is that you can set the flow meter on the analyzer during calibration. This is worthwhile because changing it from the setting used for calibration changes the reading, so you now know where to set it when you change over.
