Re: AVO Multimeter survey
I think i have heard it referred to as the WD (war department?) arrow, but the person might have been mistaken. On everything from batteries to spanners, often accompanied by the year of manufacture (which is useful.)
On many occasions i have borrowed a steel bar about 6' long, about an inch and a half in diameter, one end terminates in a wedge, the other a four-sided point. Despite the corrosion the year and arrow are still visible. It appears to be made out of some sort of unobtainium steel, is completely inflexible, quite sonorous and massively heavy- i use it in conjunction with a pivot block, for levering out small tree stumps. I think originally it was a tool for changing the links on tank/caterpillar tracks. Taken for granted for many years- but like many of the things we use it would be difficult to replace.
By comparison with the CE mark (or sometimes even the TUV mark!) the arrow effectively delivers the message- 'This is fit for purpose'
