Just a heads up for U1272A owners, I was out in the workshop earlier sorting out some tools and gadgets which I would generally take out to various larger sites and inside one of the large wheeled tool boxes was my other U1272A, anyhow I got it out and noticed that the serial number label is missing and I remembered quite a while back whilst working on a job finding a label at my feet but at the time didn't know what it had come off so it went in the bin.
Anyway, if people are going to discard the original box then they probably should record the serial number or take a photograph with the label intact either of the meter or the box which also displays the serial number. It looks like I'm buggered on this one unless it's also labelled on the meters PCB which I haven't checked yet and I have no idea where the box for that one went, I spent most of the afternoon looking and found everything else I forgot I had except for the box
