opamp comparator tester

[kt315]

Toros, leave it out,,, is not your matter. DP is excellent tester for the op amps LOL! with counterfeit DP does not work LOL!

Works with single and dual amplifiers. Here the Chinese say that depending on the operation of the LEDs, a conclusion can be drawn about the speed of the amplifier. Counterfeit ICs will be distinguished from original ones. In your version, the information is only: it works-it doesn't work.

Hogwash!
Led inertion is "legendary"!
You can conclude a squat relying on Led behavior.
Sorry, just my opinion...

bla bla bla russians bla bla bla reminder bla bla bla Lietuva bla bla bla Russia
bla bla bla Pulse Star II bla bla bla Lietuva bla bla bla Russia.
nothing useful. like always.

my last job.

perhabs for serbs Lietuva is Russia. but amigo i do not tell you that Croatia is part of Serbia. be attentionally pointed in your words.
yes, this just your matter to "pretend to be big friend to the Russian tsar" that you are not in reality. there is just Big Theater parasitizing on nominal 'general history'.

I don't mind about Russians ... the same as i don't mind about anybody else.
It's just small reminder for you.
You are from Lietuva, alright!
But every once in a while i can see in your posts something like: "In Russia they say...."
That's what you did in "Pulse Star II" topic most recently. Placing mockery on Orbits confusion and than adding: " In Russia they say..." or something like that.
So i am now returning the mockery back to you.
Why the hell you don't say instead: "In Lietuva they say..." ?
You keep pushing Russia all the time. Don't put blame on me.

this in not comparator tester. this is operational amplifier tester. open your eyes.

i use it in following repair of amplifiers and it gives instantaneous result.
yes, i do not tell you about what i do everyday be cause this forum related just metal detectors.
i checked 4556 JRC those are very wideout popular in modern mixer concoles and amplifiers,
even in D class you see them much.
i repaired FISHER detector and i sure know how important to check a comparator if there is not an instrument for the checking in your
whole instrumentary.
every VLF schematic HAS a comparator. my tester sure gives a possibility to check 'popular' ones. LM393 and LM339
every opamp for DP are checked by the tester. it gives good confidence that every sniff sniff will work good.

Ah so!?
Ok.
Than i am pulling back my words.
Your tester is most useful gadget i've seen in history of Electronics!
In Russia they say "horrorshaya durak's gadgetaya"!

I have not seen anything more useless and more stupid than your comparator tester!!!!
Probably the most trivial and most useless gadget in history of Electronics!!!

hello
yes. comparator has 'open collector' outputs. in one its state LEDs are not lighten.
pleasure

Hello, KT315. Is this the correct operation of the op amp tester? I put both LF357.
