Colibri logger errors?

Hello,

I have a Colibri logger (3.01) that on two consecutive flights gave me
faulty altitude logging (long periods of fixed altitude, and sudden spikes
to 50.000 ft+) Even though the flight was on April 1st, I tink there is
something wrong ;-) Also, it seems to be able to produce numerous short
flights of 4 seconds (this is also the recording interval), while lying
around on my dinner table ??

Has anyone out there seen such behaviour with a Colibri ? Could a fading
internal battery cause these sorts of trouble?

Thanks,

Hi Lars,

I have a vague recollection that someone had similar issues when they
applied a higher than normal voltage to the input of the Colibri several
years ago. I think the person was running it on 16V or more. I don't
recall the details, but a search of the archives of this group may turn up
something.

Are you powering it with more than 13V?

My Colibri had a problem with the altitude logging function too. I
sent it back to the factory (I live in western Canada so it had a long
way to go!) and got it back in about a week. It didn't even cost very
much.

Hi Paul,

In the glider it is powered by 12 V cells (may reach an indicaion of 13.1 V
when fully charged)
The "flights" created while lying idle were powered by the LX power/data
cable kit. I noticed that this indicates 15-16.5 V on the Colibri display.

Anyway, I have decided to send it to the factory and have it checked.
