> “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
> make the scales rather confusing until you figure the “volts per
> division” and division or multiplication factor for the 0-150 full scale
> calibration
> 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.
>
> It uses the “Banana jack” range switching rather than a rotary switch.
>  There is a rotary switch that is a function selector between AC/DC
> voltage and current ranges and ohmmeter function.  (5 positions.) Plus a
> “zero ohms” pot.  Uses 2 “AA” pencells for the ohmmeter.  I have
