Therefore, combinations of diode + diode, diode + resistor. As far as I remember correctly, the nominal resistance of the coils of one channel is 660? and the inductance is 550mH. At the end of the test results of the Mf-102 phono cartridge. The visualization changes (guess how?) When the potentiometer is turned to the maximum left or right. The tester visualizes its image as two resistors connected in series with the tap at the connection point. Maybe one of my colleagues would like to test the linear potentiometer. When I moved this washer, the tester correctly identified the capacitor and measured its capacitance. Probably due to the influence of these metals (micro-cell), the result is false. The minus outlet is soldered to a brass washer pressed with an aluminum nut. The capacitor has only been output + and - it is on an aluminum housing. I looked carefully at the capacitor and noticed something that had previously escaped my attention. Yesterday I measured the capacitor again and again pretended to be a double diode, also after the pins reversed. Is it possible that a long unused capacitor "pretends" two diodes connected in series cathode to the cathode? I probably discovered the reason for this strange behavior of the tester. The next capacitor with capacitance is correctly 2120uF. At the first measurement of the old GDR capacitor from 1987. Apart from the bananas, because each one has a different length, but I did not check on these joints.Ī curiosity about what a tester can do. But if so, why it does not go out equally, after all, all connectors are connected in parallel and the paths have the same length for each slot. Who will be so clever and say what this beast is about? Maybe it measures the capacity of paths. a 220uF capacitor on pins 1-3, and the tester sees 25pF at 1-2. Please note that in the last two photos the capacitor is connected to other pins than the tester detects. Normally, I would think that I have a faulty stand, but two different damaged ones are no longer an exaggeration. And now the time for pictures, pay attention to which outputs the capacitor is connected to, where the measurement result is incorrect. These wires on the right side are copper wire coated with a 10? 3W resistor soldered on them to unload the capacitors before the measurement. And in all joints, except ARK and bananas, because these they are triple. Pins 1 and 2 are connected and "doing" as pad 1 test, pin 3 is pad 2 test, pins 4 and 5 are connected and "do" for pad 3 test. I made a small extension to the tester and now I have quite a puzzle to solve.
