Re: AVO Multimeter survey
Hi Mike,
I am assuming the Second Digit on the Serial Number is a 0 not an o ?
A Picture paints a Thousand Words.
The correct Battery for the 48A would have been a Rectangular/Square shape
approximately 30 x 30 x 80mm Equivalent to an Ever Ready R1662.
Although, being a Military Meter, the Batteries would have been
Military Branded items.
Somewhere on the Forum, there are Photo's of the original style Battery.
In the meantime, I have added some photos of the commercial Ever Ready Equivalent.
The Same Battery was used in the 36 Range Meters.
As Dave mentioned, the Battery is held onto the Positive Battery Terminal Fork by a Brass Nut.
As regards the Felt, yes there would have been Four small Squares of Felt, one on each side of the Meter compartment.
Two Pieces covering the Wooden Standouts along the sides and Two smaller pieces Top and Bottom.
It is likely you can still see where they were once Glued down.
There would also have been Two pieces on the Stands offs in the Lid to protect the meter,
and a Strip along the bottom to stop the Transformer and Multiplier rattling around.
