All they say is set the waveform to 2.2V, which looks like it is merely centring the waveform at that point to set a DC bias of some sort.
Dunno enough about how sensor reading works to comment properly tho

Hi Andrew,
A QHY8L - OK so your results are not valid for my QHY9m.
If the pot is used in a voltage ratiometric way then it would be immune from temperature changes.
In other words the top section of the pot would change by equal proportion to the bottom section then the voltage output would be identical regardless of temperature.
However - we don't know that because I don't have the circuit.
As it will work at very low temperatures compared to the 20 degrees room temperature where it is adjusted - the temperature
could change any setting.
I am in the dark here without a circuit.
cheers
Allan
