        Waait a second... Chinese ESR meter on eBay for $20?
        That meter looks like a clone of Karl-Heinz Kubbeler AVR Mega328 tester. "The accuracy of the ESR measurement is not very high by different reasons"
        More about it here http://www.eevblog.com/forum/testgea...ecker-project/

        I know the Anatek Blue ESR goes for ~$100 (kinda expensive), but it does in-circuit testing and uses higher test currents 50mA/150kHz and seems proven by many people.
        I was going to order one, unless Badcaps wants to make their own...

          the chinese / german one may be less accurate, but it is good enough for a good/bad test and it does other things.

          i dont believe in "in-circuit" testing because of parallel loads.

            I got my ESR-meter to work !

            I brought a kit in Portugal and what a mess - the kit was announced as a MK2 and the MK2 manual was to download from the website.

            When I got the kit it was NOT a MK2 - mounted in a crappy box with crappy banana bushings, no description on how to assamble the kit - you just have to go by the MK2 manual, no explanation on the changed component values and even wrong values compared to the wrong manual - a mess I think.

            The seller was very nice to help with the problems, so it turned out well in the end - except for the mounting box - it's too crappy.

            I would advice the seller to get more organized.

              Hi all!
              I have an ESR EVB v1.1 since more than 10 years, always worked fine.
              Now it is not working properly.
              With a new 9V battery, I do the reset procedure and displays shows the normal reading "00". Than when measuring capacitors, it shows values as "40", "33", "25", randomly.
              Have you any idea?!

              Kind regards.

                The Blue ESR meter does show fault codes for many problems:
                F0- Q11 not discharging Q10.
                F1- C10 charging too fast.
                F2- C10 charging too slow or not at all.
                F3- Pulse amplifier bias Q8-C <0.44V
                F4- Pulse amplifier bias Q8-C >1V
                F5- Test current source is always on
                F6- Pulse amplifier has no output
                F7- Q3 not sourcing current
                F8- Q4 not sourcing current
                F9- Q5 not sourcing current
                FA- Q6 not switching on.


                Does the meter zero? You short the leads and press the button.
                If the readings are not steady, then check the test leads have a good connection, no oxide.

                  You said yours is over 10 years old, have you checked for dry solder joints?
