On IOS,
I only have “C” or “RAW” as well.

Also, When changing the other channel not showing the temperature, changing modes, changes the frequency and sample rates which affect the temperature reading. After changing a few times, my temperature went from 17.501 C to -257.22 C

Question regarding logging: Since the only way to get the SD card is to disassemble the meter, will there be a way to download the logged files via bluetooth connection to pc ?
