Trying to find out if the above meter was used for either 19 sets or T1154 ,R1155 installations.
Thank you

Re: Instrument Testing No 1
Do you have any reference numbers which might indicate whether it is Army or Air Ministry equipment?

Re: Instrument Testing No 1
Sorry, I don't. It is a meter, a very simple one I was considering buying. Not on Ebay on this occasion. A.E.M Ltd on the meter itself.

Re: Instrument Testing No 1
There are plenty of pictures of it on the internet, some claim it is an RAF meter, but I can see no clues on any of them relating it to a particular service. Perhaps it was used by all of the services?

Re: Instrument Testing No 1
It could be Andy thanks.I just got it in my head it was related to 19 set or 1155/54 etc.
Used to have one many years ago.

Re: Instrument Testing No 1
I've always understood, probably from seeing manuals in my Cadet Force days, that these were an Army equipment. That would seem to be reinforced by the fact that several of the pictures on t'net show a WD mark at the bottom RHS of the scale plate. If they were RAF or RN they would presumably show an Air Ministry or Admiralty mark rather than "WD".

Re: Instrument Testing No 1
In the Canadian WS 19 instruction for maintenance there is a procedure
for testing valves for emission in the event a tester is not available. It mentions use of an Universal Avometer, but a Voltmeter Pocket No. 2 or No. 3 is also suitable. Also , if no high resistance voltmeter is available, the meter in the set may be disconnected, and two prods with 6000, and 200,000 ohms in series may be used. Issue 1 15- Nov 1943. For interest, some results with above.

Re: Instrument Testing No 1
We need some pics of one! Bought this ca. 1964 and still use it every few weeks, ideal for checking sealed lead-acid batteries. When I bought it in Cannon St, B'ham, it had a webbing strap, just right for carrying it home on the bike. The silvered brass front panel used to be matt black.
