For those of us without an actual inductance meter, this project is an easy-to-build way to use an ordinary multimeter (digital or analog) to measure the inductance of coils from about 3 microhenries to 7 millihenries, with an accuracy of about 10%, plenty close enough for most DIY projects.

The inductance tester converts the inductance value of the coil being tested to a voltage which can be measured by a voltmeter. Although a digital multimeter (DMM) will give more accurate results, an...

What is this? What kinda meter is it?

It's not a meter at all; it's an adapter for a meter to measure inductance. Read the description again.

Very nice little project, carbonzit. If I didn't already have two LCR meters and a GR impedance bridge, I'd build it for myself...

Seems nice. Next free time I'll build it. 1µH is just I need sometimes...
Thanks to post !

Hi,
I planned to use HEF4093BP in place of 74HC132,but i dont know,the circuit will work or not..please help me regarding this...
thank you
