In lieu of the venerable AADE L/C Meter

k6whp
 

Since Neil Hecht's sad passing, his fine L/C meter is unavailable. While there are a plethora of Chinese units on eBay (with concomitant multi-fortnight waiting period), are there any worth considering? I have a young friend I am Elmering who would like an L/C unit like the AADE.

Recommendations gratefully accepted.

Hi,
In the present scenario, the best for home brewing appears VK3BHR for
accuracy and consistency,

here is the link



i made few with this design and are working well.

Thank you. He's a newb; what is the BEST ready made unit available - eBay or other source?

William,

I like the LC 100-A. I've checked it with the most precision parts I have (1% or better) and found it to be quite accurate. It will measure down to low values of both L and C.

At the time, via eBay, it was offered with a power supply for about $25...
 

It's a bit spendy, but the DER EE DE-5000 High Accuracy Handheld LCR Meter is very good...

I have an LC100A and an LC200A. Both of them seem to work as
advertised, however, the LC100a is an open PCB, and the LC200A is in a
shell.

My LC200A sits on the bench, and the LC100A is stored in a box. I drag
out the LC100A if I need to compare something.

I had reinforce the flimsy fold-out support on the back of the LC200A,
but otherwise, it works fine, and cost about the same as my DMM.

I've used both the LC100-A for around $15.00 and the LC200A for around $30.00 on ebay. They all have the same basic circuitry. I recommend spending the extra money on the LC200A because of its nice case. The LC100-A is unpackaged and has a higher chance of getting damaged. Both of these are quite stable and can work down to low values of capacitance or inductance. The stability depends on the reference capacitor and coil used inside the unit. You can't beat either one of these for their performance for the price.

He can larn bing new. The lc100a i have 2pcs , not working properly.

I can suppoet him woth pcb artwork for toner transfer.

Many thanks for all your suggestions. I shall pass them along to km6tnt. The LC-100A and LC-200A units seem to be a find. I might pick one up myself for when the trusty old AADE expires.

The Chinese tester are a clone of an open source project. You can find one
of the developers on the EEBlog forum. The other is on a German
microcontroller forum. These little testers can do quite a bit but even
more with the updated firm ware (1.35 I think, clones are 1,12)

eevblog forum - (227 pages)



Karl-Heinz' documentation is a good starting point:



If you have a spare 328 w/bootloader, assorted resistors and caps, and a
1602 display you could make a basic original. Other displays can be used if
you have a really nice junk box. Who has color tft touch screen LCDs in a
junk box?
