Maplin IR temperature indicator fault
For those of you who may have purchased one of these (the orange and
gray cased one which Maplin are selling for £30), I have found there is a problem when using several different types of AA cells. The unit can seem to work intermitantly, when the trigger is pressed. This is due to the +ve post on the cell not quite making full contact with the positive terminal of the unit. Basically - the terminal has part of the case plastic on either side of it forming a bit of a shoulder (to prevent reverse polarity insertion of the cells) and if the +ve post of the AA cell doesn't protrude from the cell enough, the unit become appears to be intermitant in operation. AA Pro-cells are one example which cause the problem along with the cells actually included with the unit at purchase. I actually took one back to Maplin, thinking the units PCB had become intermitant. Maplins tried some new cells with the same result and replaced it with a new item. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |
