      Acumeter VI

      Hello: In 2003 I build resistivity instrument similar to Accumeter, I use this capacitor, 2,500 uf 50 VDC, in the project: An underground survey meter by Harold P. he said: (Capacitor C1 bypasses the ac current and must be of a very low-leakage type.) and I use a very diferent lamp, is interesting the reaction, but now I want build a new similar instrument, I want use a digital multimeter, next here share the experiment.

        hi
        in the underground surney meter project wath amper need for ac 24 volt?
        and wath is better frequency ?

          hi. can ENYONE post a complete and full detailed schematics for accumetre pro vi?
          Thanks a lot.

              Cave

              Please I am requesting any information on Accumaster,Accumeter,MML,OKM cavefinder and so on. Which is better? I do not care the cost price and similar crap.(39,95 – 3995)Work or not work?
              Thank you, Toni.

                Accumeter VI

                Carl, Will you build me the equivelent to the Accumeter VI including the rods and wire TURN KEY? I will pay you of course. I am not schematic savvy at all and I am totally disabled. I have some acreage to search. So all would be appreciated.

                Thanks,

                Bob

                    Hi
                    I´m looking for a circuit to allow me to connect arc geo logger to my accumeter IV
                    Basically i understand this must be a circuit that can convert resistance levels from accumeter to audio levels.
                    If any of the members can help i wil appreciate a schematic to add to my accumeter IV
                    In advance many thanks
                    Nelson

                        Does anyone know how to mod accumeter to digitilice signals and plot results via software ?

                          The Accumeter is a really poor design. If you're going to go to the trouble of adding a data logger then you should just build the design that was published in Everyday Practical Electronics several years ago:

                            I have AEMC 3610. I used two connection points, has 325 Hz square wave, precision 3% and taut-band movement.
                            I dont know, maybe someday detect something buried conductive,,,
