Try to set it for the 10 o'clock position. Should give you about 50% RH.
50% is a bit dangerous, cos need to take into account +/- 5-10%
for me i set to 2 o'clock, my range usually 40-45%
It should be 45-55, so 50% +/- 5-10% is good.
Set it too low, and you risk damaging the rubber and lubricants in the lens.
i mean my range for my dry cabinet is usually 40-45% when i switch to 2 o'clock
the recommended range is like you say 45-55%
so for my range of 40-45% its actually within the 45-55% after u +/- 5-10%
if you set to 50%... if u add 10%, thats actually 60%... which is out of the recommended range.
hi again..now i just really wanna know which way should i turn the nob if i want to rise or lower the percentage..
this guide come together with the dry cabinet...
