[R-390] OT:Help with AN/URM-223 (ME-297) Batteries ?

[Michael Melland]

I just received a NIB AN/USM-223  (ME-297) FET multimeter.

I know that the six original mercury batteries (BA1312=NEDA1100= 1.35v
Eveready E1 cells) are no longer obtainable.

I've been told that on later ME-297's the military switched to 2 ea 4.5v
Energizer 523's after some sort of modification..... and that there is
another mod to allow use of ordinary alkaline AA cells.

Anyone know what  I need to do to use the Energizer 523's or AA's ?

Thanks,

Mike
