Hi Everyone!

How is everyone's room temp reading?  Mine is off by 10 degrees F.  Any thoughts?

Thanks!!

Mine is always high, but to be expected in a almost sealed xox my hand heats every now and again, but I don't have an accurate thermometer here to say how high.

Hmm- I realize I'm looking at the device monitor info, and that my device is plugged in- perhaps the charging circuitry raises the temp by 10 degrees F?  Might be conceivable!  Especially in a closed box!

You need to run case analyzer and get your thermal coefficients for it to be right. Once you have done that it should be pretty bang on.

You know, John has a very good point here!  I just checked out the case-analyzer portion of escribe, and the Delta-T for charging on USB is 10 degrees... that's right on the money for our house temp at the moment (91-10 = 81).

So, I bet it's correct!! [smile]

I have so many computers in here I struggle to get the temp below 28 C at this time of year and both time I have run case analyser it spends the first hour waiting for the temperature to drop, I got quite different results each time, but the were different ambient and doff versions of escribe.

Those aren't that different, really. Either should get you within a few degrees of correct.

I was meaning the cooling and heating time constants were different, I am not worried about and just posted as the topic came up.
