I expect you might need to put the meter in your pocket for a few min on
a -10F day to get the display warmed up, but you do on the Fluke as
well. The HF meter does indeed work perfectly fine in 104F, I've tried
it.

I just put my $3.99 multimeter into a freezer. After I put kids to
bed, I will report on how it works. My feeling here is that its
performance depends on how much voltage the cold battery would
provide.

I've used my Fluke 87 in sub zero weather in CT and the display is a bit
sluggish if you don't put the meter inside your jacket now and then to
warm it up. Since I moved to TX I've bought a handfull of the HF $3
meters and have used a couple in 104F with no issues. I've not used the
HF in cold or the Fluke in really hot yet.
