[ARC5] Schematic/specifications, etc on French Multimeter??

[Gaston Dessornes]

Hi

This Metrix  was my  first encounter with  good metering  in...1952-1954 in 
my school at Le Mans, France. It was noted to break its  bakelite body  when 
droped on  concrete  floor. Mine had been reglued a couple of times!

see http://retro-forum.com/viewtopic.php?f=3&t=20088

Where a collector is offering  a notice and documents for  the asking .
Have fun!
Gd

> “Metrix” model 460, Serial number 114105.
> AC/DC ranges: 3 volts F/S thru 750 volts F/S at 10,000 Ohms per volt.
> AC/DC Ma. ranges from 150 ua. to 1.5 amps F/S.
> Ohms: 0-20K F/S and 0-20M ohms in 2 ranges.
> plus a db scale (no impedance specified on meter face.

> A very neat and found very accurate meter  although the ranging factors

> The actual voltage ranges are: 3, 7.5,30, 75, 150, 300, 750, current 
> ranges are 150 ua.,1.5 ma., 75, 150 ma and 1.5 amp.
