I never tried testing 18650's.
Just lead acid, nickel metal hydride and nickel cadmium's.
Can't recall really checking for charged verses dead.
Lots of charged verses charged to compare their health is all.

Those minor upgrades add up to ease of use!
The longer leads would keep me from dragging my Blue around so much!
Nice job on the holder!

bcstedt,..

About your FA error code.
Lots of reading gives me this from Bob Parker. (Don't try out the self-diagnostic function unless you really need to. And don't use a 9V battery with the diagnostic function because it will report an 'F2' fault which probably doesn't exist. It must be powered by 5.5v to work properly.)

As far as errors and faults check here. http://www.bobparker.net.au/esr_meter/esrprob.htm

Lots of good Info on errors and problems with the Blue ESR Meter from Bob himself!

Thanks for the printout. Doesn't look as "professional" as the original but 10 times more useful.

I should have printed it out at work on our $3000 copier instead of my monochrome $80 home laser printer. It looks good enough and I didn't use sticker paper either. I was just really careful with packing tape and used a razor to trim the excess.

Interesting the "old" table seems to include some compensation to limited testing frequency, but the "new" graphs do not...

Now to attach a table to the AVR transistortester ... heh...

Looks Good Enough to do the job jayjr !

Everybody can use it if you want. Its not to fancy but it works!

I remember typing the omega / ohm symbol was a pain for me!
The colors just looked kinda cool. I saw similar on the net and they got added at the end.

I have two printers that i use. One HP Laser Jet P1006 for cheap black and white and
a HP Office Jet Pro 8210 for color printing.
