Thread: Digicab Problem

    Default Digicab Problem

    Just like to check if anyone got this prob... I just got my Digicab (DB-036) last month, after a few days managed to get the RH stable at around 44-46%. Haven't opened the dry cabinet for the last 4 days, but suddenly this morning I saw that the RH went up to 55% (it even went to 63%) at 1 point.

    I took the battery out of the meter, and changed a new one, and increased the absorption rate. However the RH still stays at 53%.

    I hope nothing is spoilt, its a new set, and its left by itself, so why should the RH suddenly increase?

    Just realised something, I was trying to adjust the knob just now, and my finger accidently brushed against the behind of the knob...realised that there is actually a small heatsink behind it... AND ITS WET!!!!

    That's how a thermoelectric dry cabinet is supposed to work.

    So that's normal rite...never realise that, noob in using the dry cabinet.

    Anyway, after i increased the absorption rate somemore (from the previous 9 o'clock position to 12 o'clock now), the RH is back to 44-45%.

    These cabinets are basically poorly insulated refrigerators. A Peltier element (http://en.wikipedia.org/wiki/Thermoelectric_cooling) is used to create a cold area, and water is condensed from the gas to the liquid phase there. (I then trickles through an opening to the outside of the cabinet, were it evaporates - assisted by the "hot" side of the Peltier element.)
