I bought a digital temperature equipment, consisting of a inhouse table unit and a outdoors unit. Cost = 25 USD. Cheap? Yes. But let's have a look on inside after the problem, which started just a few weeks. You can read the inside temperature, clock works, date works, and you can use the alarm and shift between the four channels, but the receiver does not take in the signals from the little sender on the wall any more. I dismantled the box and marvelled when I saw the shit I payed for. It's a wonder that there are any functions working at all! Now, what caused the dead receiver was a flow of iron from one screw (upper left corner ) . There is a bridge of corrosion products (brown and green) from the screw to the thermistor (RT) continuing to the rest of the circuitry. When I washed the card and dried it, the reciever worked again, Now, folks, here comes a question for the sharp TNetters: "How can the screw be so rusty and deliver iron ions when it's not connected to anything? It's just torqued into the plastic body. The other screws are identical, but have not been involved in anything. " The box has been on the kitchen table and has not been exposed to humidity or any else abnormal condition. The two 1.5 V batteries are removed on the pics. Hope the gregorian Steve will help me with the photos. /Inge ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
