Dank - thank you for getting back to me. Soon after I posted my message, I realized that I could back into the readings. Apologies for me spinning your wheels.Im not sure. Id do it in wood setting but id just try the diff settings and see what happens. If theres different readings un the same stem from different settings id look at your manual book. Im guessing setting A but im not 100 percent sure. Id play around with it. Mine only says wood or building setting. Not a bunch of options on mine.
I tested a nug that's in a Grove bag reading 62% RH. When I press the spikes into the nug, I get the following readings:
I used the meter for a harvest at the beginning of the year. When I turned on the meter earlier this week, the wood type was set to "B". Between that and the testing I just ran, I think B is the appropriate setting.
