Tried to calibrate with what I thought was the olive oil. Nothing happened saw no half and half screen, just indicator line that never moved even turning calibration screw. I doubt it was olive oil because it fused with the plastic of the device and melted it.Took this long to use because I waited for honey harvest to try. This was weird.
