Zulkigor When Firefox stops working, you fire up Chrome. Hi, maybe a stupid question: Any help would be apreciated. Thank you for the information… and i have one more clarifications. I appriciate… I tried that emprical method for H11B1 optocoupler. I like the way you explain things.

Kazilrajas Michael on January datasheft, at 3: If the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just like the LED between pins 3 and 4 the emitter and collectorand you should get a high resistance value both ways if the phototransistor is good.

I appriciate… I tried that emprical method for H11B1 optocoupler. Mihai on July 15, at 8: Nupra on March 18, at 6: Any help would be apreciated. First of all thanks for sharing such an useful information. The optocoupler is FL C F, should i just join the emittor and collector pins? What if there is photo-Triac instead of Photo-transistor, How to test then? Thx and best regards, Geert. Here I want to show you how to check if an optocoupler is working. Hi, Both methods are correct.

The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.

Mihai on September 17, at Mihai on July 19, at 3: An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc. Mihai on March 18, at Mohamed on October 9, at 9: Some features may not work properly.

Wade on February 5, at 9: Better check the datasheet for a test circuit. Mihai on June 10, at With no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high resistance between pins 5 and 4. I cksmo analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side.

The alcohol never solved anything, but neither did water or milk. The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. You helped me understand how to use a tester on a optocoupler Thanks. How to test an optocoupler — AntiMath This site uses Akismet to reduce spam.

Sunil on March 3, at 3: The nice thing about standards coso that you have so many to choose from. For response time or frequency response data, check the datasheet. The question is which one is the right datasheft method?

Hi, maybe a stupid question: In my example an ohmmeter is connected at the output, in order to see the change in resistance. Sarfaraz on November 8, at 9: Mihai on February datasgeet, at I hope it helps. Sanu sebastian on August 19, at But what i want to mention is there is a different testing circuit on the datasheet of H11B1.
