oscilloscope
#1
A lot of years ago a good friend of mine obtained a oscilloscope.
Now i have that thing on the attic.

I don't know much of those machine's but you can learn everything if you want.
Is it a good device to use it for testing our 18650 cells?

Dis/charging behavior? to find out the state of health? ect

Can i use it for something?



thanks in advance

That's a beast, I doubt you'll be able to find a productive use in capacity testing cells, but it's a nice thing to own.

It's an old CRT machine so the trace might take 30s to appear - does it ?

Input probes are cheap and it's got inbuilt outputs so you'll at least be able to see if the input stage is alive.

Apparently its classed as a classic, so dont throw it away (even if theres no life in it)

Reminds me of an old Heath kit scope I used to own.
Just like the heath kit, yes it should still be good. You might want to check the timing using a 555 circuit or something.
As for use in capacity testing?

Could use it to check the charger your using or the little charge modules for how clean they might be and add additional capacitance to correct them etc.
Even if it's no longer calibrated.

Very accurate voltmeter

That's a very nice vintage equipment from the '60s with a lot of tubes. I've a 453a from the '70s, mine is tubless, the first scope with full silicon based technology.
543 can be a pain to repair, if it's broken, parts are rare to find, but the service manual is available with a lot of schematic and flowchart.

Unfortunately it's not good for cell testing, but if it's working it can be very useful to build a tester.

Also it's only accurate if it's calibrated.

My advise: repair it (or maybe leave as it is) then put it back to the attic, a few decades later it'll worth a fortune.

I was planning on repair it, IF my friend didnt do it.
If he did, its better then new, if he did not, he had a other project.
I did not know they could be worth any money, or that they where special, but definitely not fore sale

There is a small store in Hoorn in Holland, that can do magic with tubes.
They also repaired the amplifer of my oldest jukebox from 1932.
Still have to finish that jukebox, shame on me......

To be honest, i don't even know how to use an oscilloscope, or what you can do with it.
All the cable's where thrown away, when i got the oscilloscope)-:

The 555, that brings back some memory's, with also i believe the 4086

Thanks for the link and input, was really fun to read

Far from it! Oscilloscopes are measuring devices for time, not amplitide.
Or in case you where joking, in which case swoosh!

Pretty useless for anything sub-Hz, and antiquated for everything above it. Might still hold some value for a collector. Boat anchor perhaps?
No. cells

LOL boat anchor.
Anchor indeed.

So its only for timing and to "pair" audio transistors and such?
It is thus pretty useless for me, to bad.
I will keep myself then with my trusted multimeter, and leave this "anchor" in peace

Thanks

I need a boat anchor, so if you have no use for it ........  Angel
