      Cheers!
      Do note that the original seller you bought from (At least the one you linked to originally)
      Also sells it assembled.
      So he really should be able to get you either a schematic or at least a picture of it assembled

        ive emailed the seller a few time all he says in the return messages is "so you cant weld this" i think he means solder it and he has no schematic ive asked twice and to confirm one of yesterdays post i made

        sorry about the confusion (was one of those days yesterday nothing went rite) i misscounted the ebay picture and now just re checked the kit all again yes there are 24 spots on my pcb and 24 resistors fitted on the ebay picture yes just counted ny resistors again 23 plus 1 zero ohm (which isnt shown in any ebay pictures) but without any schematic im still stuck anyway.

          Ok, incase you did not notice the picture in his eBay AD is not of the item he sells.
          They are watermarked "kiss_buy".
          That seller does have the same meter for sale, search for "ESR 2016" in his eBay store...

            I hope the banggood kit has instructions!

                    Re: ESR meter upgrades

                    if you look really closely at the pcb you can see it has the parts printed on it so your fine with that kits thats a good price too i keep forgetting about that site.

                        Re: ESR meter upgrades

                        post pics of both sides of the pcb that are good enough to see all the tracks clearly.
                        i'll work it out for you.

                            Re: ESR meter upgrades

                            i almost finished the pcb stuffing list,

                            verify something for me.
                            x2 110 ohm
                            x1 5.6k

                            are you sure about those - specially the 110ohm - is it actually 1k?

                              Re: ESR meter upgrades

                              x1 5.6k measures 0.56 on 20k scale
                              x2 110 ohm measure 1k my mistake sorry
                              x1 2.2k is 2.2k (im not sure if i wrote this as 2.2ohm)

                                wouldnt .56 be 560ohms?

                                        c5 and c6 are 100uf 25 volts in the kit
                                        then i have x4 104j
                                        x1 103j

                                        cheers again stj for your help

                                          16v was a minimum figure,

                                          104 = 100nf
                                          103 = 10nf
