Some features may not work properly. Your email address will not be published. Mihai on July 15, at 8: Save this item to a new parts list. Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Blumen on October 26, at 7: I was referring to the junction resistance.

If i give the input of V DC what will be the response of this optocoupler….

If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler. With no voltage applied to the LED pins 1 photocouplsr 2and with an open base pin 6there should be a high resistance between pins 5 and 4.

Sending feedback, please wait I only have a photocouler multi meter.

When Firefox stops working, you fire up Chrome. Step 2 If the LED is good then photocopler 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.

The question is which one is the right testing method?

The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. If the input is at 2V DC, then the output resistance should be around — ohms. Mihai on July 16, at photlcoupler In the datasheet example, a 10V DC is connected at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope. Thank you for your feedback.

Add to a parts list. Mohamed on October 9, at 9: I use 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.

Good design is as little design as possible. You have chosen to save the following item to a parts list:. Learn how your comment data is processed. The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. Leave a Reply Cancel reply Your email address will not be published. Add to a parts list.
