Thank you, Smoorman.

There is no changing the reading you just have to compensate for it per the example in the video. For example if yours says 71rh instead of 75 you would add 4 to your reading.

Very well done !! Thank you. But I missed the part where you change the reading ?

Thanks, that's the way I do mine too, is with salt.
Alot of folks use Bovedas as well.

Hope you find it helpful. I literally created it because other videos on the topic seemed to miss some important points.
