It is not easy to tune one that is not digital, i assume you are not using once since you are tuning it. First you set it without placing anything in it. It take about 1 day to stable, then fine tune it until it reach the mark of ~45%.

FYI, do not place your cabinet near the sun or fan blowing at the cabinet. Locate a dry box at a place where there is less interference with the environment changes. Anyone place it in the storeroom?

Which dry cabinet are you using? If you are using the Digi-Cabi, you can try tuning to between 12 and 1 oclock. This will maintain the RH value between 44 & 46%

Get a seperate digital hydrometer and put it in your cabinet for a more accurate reading. Usually the two will differ slightly. Take the reading with a pinch of salt. As the number is "Relative Humidity" it is not an exact value. It is relative to the base settings from the country of origin so 64% RH in the cabinet is not the same as 64% RH in Singapore atmosphere.
The relative humidity of an air-water system is dependent not only on the temperature but also on the absolute pressure of the system you are taking the measurement.

I have 5 models of hygrometer and this one is very accurate even though you can't calibrate it. I paid about S$50 with shipping.

I'm using the digital dial instead of the analog type, I never do any adjustment thru out the years, it just stays ~45% once settle down.

anyway, give it some time to settle down before do any tuning.

Why not just get it directly from the distributor, Digihub, at Tagore Lane? You can get some advice from the people there too...:thumbsup:
