Chuck, K7QO had done some preliminary testing of various LC meters and posted it on his webpage.? I gleaned this info from the yahoo group QRP-tech, in case anyone finds it useful.?? I would stay away from the LC100 that Chuck describes as "Left" terminals, at least from my very limited experience...
"I started the comparison of some LC meters.
Using the LC200A from China, the AADE L/C Meter IIB with the
famous Preston Douglas, WV2J, cap mod and two LC100A
L/C meters. The LC100A's on ebay come in two variations
(at least) that I see. One I call Right, as the component
terminals are on the right front of the PCB and Left for the
terminals on the left side. I have two Rights and found
that they have a Rev 4.8 and Rev 4.7 firmware show at
startup, so thought it would be interesting to see if there
was an effect. None that I can see.
OK, before you weigh in on the numbers. This is the first
pass and only for discs caps Got a whole set of mono, mylar
and electrolytics to do. The AADE fades on the electrolytics.
Meaning that the measurements are way off and low.
I'll try to get some more done tonight and put in a table.
I made a mod to the LC200A. Bought two terminal posts
that have a screw down so that I could build a fixture and
get exact reproducing measurements. I will come back in
a week and redo them to see if there are changes.
Good results between all four meters and most within 1%
and some points that were off by more than 1% and I will
come back and remeasure those later. I just take data.....
I have one of the Frog Sounds transceivers ($12) coming
to the mailbox today. Some one mentioned they found
shorts in som caps and I will measure them all for the heck of it.
LC200A - $29.95 on ebay
AADE - $99.95 in kit and $149 assembled and no longer available
LC100A - about $14 USD on ebay for Left sided terminals
If you have an LC100A with the terminals on the left, send me the
Rev that you get on power up. Please. The LC200A is Rev 5.5,
so it has the same uP processor and just a different PCB and
comes with a case."
