Default Re: AVO Multimeter survey

Dave, Andy, Phil,

Thanks for all the valuable input on this.


Going Forward then, I will record any early DC AvoMinor as "DC AvoMinor"
All other AvoMinor Models will be logged as simply "AvoMinor" (since DC variants or these later Models exist).

So, lets see if I have the basic Story right so far.
As per Phil & Andy's Post #2309 & 2310 there appear to be at least Three Types of the Early DC AvoMinor.

1. DC Avominor (standard)
2. DC Avominor H
3. DC Avominor HR (High Resistance)

Moving onto the Model 1 (Universal AvoMinor), as per Dave's Post #2301 & 2302 we have at least the following Type Variants:
1. Type H
2. Type HR (Actually DC not Universal)
3. Type U15
Plus, one would assume, the Standard version of this Model?

Then we have the Model 1a which I assume at this Stage, has only been identified in a single variant?
For the Model 2, does this later Model have the same Variants as the Model 1 ?

The Model E (A Military DC Instrument not Universal) in a Model 1 Shell.
Has the E been seen in Model 1a or Model 2 guise?

One remaining question I have regarding the Early DC AvoMinor is what is the Stepped Side version?
Anyone have a Photo of One handy?
