Looks like good fellow already posted for me.

It happened that I had a new Craftsmen tool catalog in yesterdays mail. I looked at the meters and they don't have the lower priced ones any more. Too bad, it's a great meter. I have several more expensive DMM's that I leave on the shelf most of the time now that I came up with that one. It's small and convenient with full functionality.

I would suggest you take Good Fellows part number and call the local Sears stores to see if they have any left in stock. It is an amazing instrument for the money.

When I was in college (Electrical Engineering) I was working in an electronic component burn in house at night. This was '73 '74 time frame. We had some 3 1/2 digit Fluke DVM's that cost well over $1,000 in seventies dollars. This little $27 meter will do anything they would do plus a lot more. That comment is without checking tolerances, but for most purposes the tolerance of most any DMM is just fine.

Good luck,

Sears doesn't have the 34-82040 but here are two that they do. Both claim to measure "frequency" and the red one measures temp to 1800 deg. It's $29.99. the the other says it has a scope. It's $53.99. What do ya think?

The $29.99 one

I want to see a picture of a Simpson 260, just to bring back memories;)

Here is one of my old favorites

Maybe we should start a Multimeter forum
 

While we're at it, what plugs into the DIN connector on the top one.

frequency function will do nothing for you. I will do my best to remember to get the number off of mine tonight and post it.

You need to look at the list of functions. It will be clearly labeled "Duty Cycle" or " % "

Happy hunting,

PS, I haven't seen a Simpson 260 in a very long time. It seemed like every one I ever had my hands on, had a broken case. My Dad had an optional case that had a rolltop door on the front. His was always in good shape. LB

the 'socket' provides means of testing transistors. Tests hfe (gain) of NPN or PNP transistors. Also that measures capacitance. Nice instrument to have for $53.99.

The pic of the first MM doesn't not have 'DC'. Can't make out the second one.

Art: cut my teeth on the 260s!

Here is one your GrandFather propably did ....

Did I misinterpret this are or we talking about frequency in another context?

Arthur,

The Simpson looks just like the one I salvaged from work, back in the days I worked off-shore. The case was broken (like everyone Larry has seen) and the Techs were trashing it. I rescued it and used it for a long time, until my ex-brother-in-law borrowed it and lost it. All I have left is a set of spare leads for it :(.

Mike
Yeah- they were repairable
They even came with a schematic/trouble shoot section and a complete parts list.
I have one NOS still in the leather case that has never been used
for keeps-sake..

When I was a kid, we sent away and bought a Kit and assembled it .
Gone-bye days , for sure

Here is one I made years ago

You guys are leaving me hanging here! I never got an answer to my last post about frequency.

As said , freq is the amount of complete cycles in a time frame
of 1 sec.
Freq is measuresd in Htz [ times per sec.]
An example of this would be household current being 60 Htz [cycles per second]
Or , in England , 50 htz , etc....

Duty cycle is not by time , but by comparison of time ON to time
OFF of a cycle , So, it is measure in ratio/percentage.
Example :
A pulse of on time of 1/4 sec and off time of 3/4 of a sec. would be a duty [work] cycle of 25% or a ratio of same....

Generally speaking....

With a frequency of 1hz.
