QUESTION - How does it work ? PROBLEM - We recently obtained the IVAC Temp-Plus II electronic thermometers. They have an alarm which sounds off if the thermometer is not returned to its wall mounted case within one hour of a previously set time period.Its function is also crippled at this point in time. There appear to be no external connections between the thermometer and the case. I can see in the base of the case what appears to be a 2 cm long piece of metal embedded in the plastic. QUESTION - Could there be some sort of magnetic induction switch functioning here ? Thanks from the curious but ignorant.

I have seen a hand-held meter that had a drop-in recharger that had no electrical connections. Essentially there is a transformer with the primary in the base and the secondary in the hand-held portion. John .....................................................................
