Have a new Kestrell 4000. Does anyone know of any hidden keystroke
functions??

I have had one for about six months and am very happy with it. I don't know
of any hidden tricks (have mislaid the manual in any case) but it all seems
pretty logical.

Cross checks with numerous other reports such as metars, suggests that the
level of accuracy is much better than the specification. Indeed, mine seems
to be +/- 0.1 degrees C.
Good battery life as I have only just had to replace the first set. A fine
piece of kit. Mine lives outside but sheltered with a cover to protect from
rain.

One caution is that radiant heat from the hand can quickly upset the
readings. If anything, the instrument is TOO sensitive.

Yes very pleased with mine. Kind of difficult to get reading when temp is
low. Heat from body quickly sends temp rising. I place mine outside with
30 sec recording to get temps. Was wondering if you could get hidden
screens like for maintanance, eg. by turning on while holding one or more
buttons etc. Other instruments, like gps, have "secret screens" for
testing.

DO NOT play with the Kestrell 4000 calibration - I did and I totally messed
it up . Eventually I was able to re cal it by using a hospital baby
incubator or all things. I was able to set the RH to 25% and then 75% for an
hour each - something that is just impossible to do - Also I was never able
to find anyone in the UK who could do this for me.

One thing that lets the 4000 down (Not sure if this is the same as for the
3000) is that the annemometer only reads up tp 87 mph - and this means that
I have red linned it more than once during my hurricane antics.

All the best

TOO LATE. Ha ha. First thing I did was play with the baro cal. Luckly I
didn't f#$% with the RH. I finally got the baro back by adjusting to
nearest slp from wx office with my altitude set. After some playing around
and fine tuning it seems to be quite accurate now. Used procedure in
manual. Look for shallow pressure gradient on wx map also.
