      Hello
      Looks to me as an isolation meter like Megger , used for mesuring
      lines, motor , capacitors , transformer resistances i own a russian one
      and use it for testing if capacitor is good

        Indeed it is a Megger, used by electricians to measure insulation resistance.

            Pierre,

            So you use it to see if a capacitor is good? That's brilliant!. If the resistance is max, then looks like the capacitor plates are not touching?

              Make sure that the voltage rating of the capacitor exceeds that of the Megger voltage, otherwise you will simply blow up your capacitor!

                Hello
                My russian megger gives 100vDC , at maximum crank rate
                Since 1980 i never blow a capacitor , as all i checked are currently
                160 till 400 v capacitor , it’s a live proof , you are more shure
                then mesuring with a multimeter

                  It is insulation meter or megger (name coming from mega ohm meter).

                  But somwhere there should also be company name/type written
                  Show that instruction lid and scale more closely.

                    hello
                    i use this megger for isolation , but for correct capacitor value
                    i use an rohde und Schwarz capacitance bridge , it's very accurate
                    megger is MY ???

                        Yes, but don't you know how fun is to blow up 16v electrolytic
                        capacitors via connecting them to 230v AC!
                        Lot of smoke and small aluminium pieces everywhere!

                          hello
                          thanks val for infos

                          when testing a pcb at my work , suddently it exploses it was

                          a 10 uf tantale capacitor put wrong side , it remains just

                          the 2 wires on pcb and pcb was damaged it was also fun
