When I had the temp set at a higher gain and the offset to center the
trace, it would basically flat line then suddenly be all over the place.
Are the chips available anyplace? I do have a bit of experience of
soldering.
Thanks again.

Nothing looks wrong in that snap Shot
Your osc (which is the main cause of the out of range error) is
working fine and under control and has near zero volts on it's EFC.
Take a look at the screen when you key "& ", that has the screen
with the Max and min DAC setting info on it.
Should be +5 and -5 (set with "& N -5 Cr" and "& x 5 Cr")
Also can use "F A" command to turn on the Altitude filter
If it misses up again, use the "\" key to get an automatic screen shot
save without it first updating.
If "bonkers" is about 1 deg, maybe you have the low resolution Temp
sensor chip (It has about 1/2 deg C resolution).
That does not really matter or effect anything important unless you
are doing temperature control with LH.
If the temp never changes, then likely the DS?? surface mount 8 pin
temp sensor chip is broken and should be replace
Do note the way you have the temp plot set up (Zero offset and low
gain) you will only be able to see large changes on the plot.
Have fun

I may have jumped the gun on this. I cycled the power a few times and it
appears to work.
Note the temperature never seems to change. It sometimes goes bonkers
then settles down again.
Attached is the screen shot
Thanks much

If you are using LadyHeather, Post or send me a screen shot using
"W S Cr"
Maybe just that the min or max Dac values are not set to - + 5V, or
something else easily fixed.
