Title: Choke Inductance
Post by: TIMBO on April 12, 2019, 05:56:17 am

Hi guys, I have several chokes and I have no idea what their Henry are OR is. :dontknow:

I have a Fluke 187 and I not sure if it has a inductance mode.

As far as I know from viewing the owners manual no mode for that.

Here's a video on that tester kagliostro suggested. It looks pretty cool.

+1 on kagliostro's suggestion.


I bought the 1st pictured tester from Ebay, $15.


I've plugged a lot of resistors, capacitors and BJT's into it. Works like a charm. I hadn't thought about trying chokes.
