Anyone know what the differences are between the Series II and Series III?  I can see the Series III has a mirrored meter but not sure what other differences there may be.

Also, I'm not finding a Series III manual so that would be nice as well.

Thanks,

Just as a SWAG you might try simpson260.com <http://simpson260.com/> (which for some reason isn?t resolving right now in my browser)?may be some info there or at least a lead.

Hi Dino,

That's one of the first places I looked.  The -AF and Series II models are there but not a Series III.

Thanks,

Hi, 

The 269 series 3 used standard banana plugs, the same as type 260 series 3, 4, 5, 6.  Earlier type 269's used pin jacks.
Judging by my 1977 Newark catalog, the 269 series 3 scales 
didn't change from the earlier series.

I have a Simpson 269 (first version, ca. 1957) 
but must say I'm disappointed with the meter ballistics
 - there is quite an overshoot when metering D.C. voltage.  
My Triplett 630-NS (a selectable 100K or 200K Ohms per volt VOM) 
does much better in that area.

The positive terminal of my Simpson 269 is the negative lead
for the Ohmmeter function.  I don't know if they continued that
in later versions.

73,
Ed Knobloch

Hi Ed,

Thanks for that information.  From what I've read, they also improved the meter movement in the Series III.  I don't have any other 269s so nothing really to compare it to except my 260s and Triplett 630 (which I like very much).

If I understood what I read elsewhere, I think the 22.5V battery is a different form-factor in the Series III but I don't have any other information to back that up.

I'm going to get this one Saturday so hopefully nothing's broken about it that the one picture I have of it wouldn't have shown.  I'm looking forward to opening it up and seeing if everything is intact.

Thanks,
Barry - N4BUQ

   Actually the polarity of the leads in the Ohmmeter of a Simpson 260
is dependent on the position of the DC Voltmeter polarity switch.

   This is not the case of Triplet meters, which is the only reason 
Simpson 260's became so
popular.  Once the crocodile clips are attached to a diode (including 
the stud mounted
kinds) you test forward es reverse by rotating the polarity knob back es 
forth es back.
Very handy if you have 25 or 50 diodes in string assemblies to test for 
open es shorted
diodes.

Picked up the 269 Series III today.  Everything works and it is in great shape.  Came with the leads with the alligator adapters to boot.  The plastic handles had broken where the probe tip presses in but that's an easy repair.

I also scored a Triplett 310 with the Model 10 AC clamp and Model 101 adapter/multiplier all in the tall leather case.  I thought I had both leads but somehow one of those either got away from me or I imagined both.  In any case, the one I have is in pretty poor condition and I'm looking for new leads.  Anyone know if what is now known as mini-banana plugs are correct for this meter?  If so, I should be able to fashion some new leads with some replacements.  BTW, the 310 appears to work in all modes I tested including the AC clamp.

Thanks,
Barry - N4BUQ

Hi, Barry

The leads you want for the Triplett 310 series 
is their part number 79-153, which has the needle point.
Mine have an "M" impressed in the mini banana plug, which indicates
the manufacturer.

https://www.triplett.com/search?type=product&q=79-153*

You should be able to find a cheaper source.  I bought some leads about 20 years ago, when I was acquiring Triplett 310's,
and I recall the price for a set was closer to $10 then.
I guess $25 now is like $10 then.  I'm getting old.

Here's a place that seems to sell the equivalent mini-banana leads, but without the alligator clips:

Hi Ed,

I'd seen the Probe Master site but had forgotten that Triplett still sells the 310 so those leads are also available.  Sometimes I let the fact that I got something inexpensively influence my decisions to buy things for it that are more expensive than I'd like to pay and I need to look at the overall price instead.  I mostly would like to replace the short red lead from the AC clamp as that one is not in good shape and I can use one of the mini-banana to some other fitting for that and can worry about the leads separately.

Thanks again for the pointers!

Thanks,
Barry - N4BUQ

I looked some more into the Model 10 today.  The other day when I compared the range resistor's values to the schematic, their values didn't agree and, mostly, were running a bit high; however, I realized that those are wire wound types and, so, they should not have changed much if at all.

I opened the Model 10 again today and now I see that the range resistor's values are labeled and they check extremely close to their labeled values; however, those values do not agree with the schematic in the booklet I have that came with both units.

This brings me to wonder if I have a different version of the Model 10 and, even more so, which version of the 310 I have.  I understand there are a few(?) different versions but I cannot see anything in the 310 or the 10 that indicates which version those are.  That leads me to think that they both are the original versions but I don't have anything to back that up.

Is there a way to tell which version I have of both/either unit and, mostly, were there different versions of the Model 10 that might account for the difference in the resistors that are in mine?

Thanks,
Barry - N4BUQ
