Bro...don't confuse our Bros more lah. Analogue type (everybody knows) is open loop feedback circuit. Digital type (everybody also knows) is closed loop feedback circuit. The analogue type is known as analogue because the setting is via a mechanical dial and it is highly accurate but it takes awhile to settle down. The so called digital type is only accurate in its setting but because of the feedback loop, it will yo yo from 45 to 47 to 46 to 45. Still accurate though until the micro controller goes kaput.
just got my first dry cabinet from the sale @ sgcamerastore ystd too..
I would like to ask how am I going to calibrate a new dry cabinet?
And which RH is the best?
erm... im using Db-036
Calibrate dry cabinet means you want to know how to set the RH level or how to calibrate the hygrometer?
Hmm ok, set the dial to the 11 o'clock position and leave it for the night, look at the level of the Rh the next day and fine tune it accordingly, most likely you will end up near the 1 o'clock position
Octarine: they did put 45-55. but some people did say its better at lower RH. so im just checknig with the more professional people here =]
spree86: thanks. i will leave it for a night and see how it goes.
ziploc: hygrometer can also calibrate meh? =]
I am currently a user of DB-036, My RH vary between 43% to 47%.
How to Calibrate a new dry carbinet
Step (1) I adjust the controller to 12 O'clock postion.
Step (2) I let my newly dry cabinet condition itself by leaving it empty for 8hr to 12 hr.
Step (3) after 8hr to 12hr of conditioning, the HR should be around 55% to 65% ( if i still remember correctly)
Step (4) open the door and now, adjust the controller to 2 O'clock postion.You will notice that the RH start to drop at a constant rate
Step (5) give the cabinet anothers 3hr to 5hr the RH will drop to the minimun of 40%.
Step (6) YESHH!!! can start to store all your camera equipment in already.
(The above steps are what i did when i get my Digi - Cab Dry Cabinet. It work well. )
