    Capacitor tester in circuit

    The one who is engaged in repair of household or industrial radio equipment knows that it is convenient to check the serviceability of capacitors without dismantling them. However, many capacitor capacitance meters do not provide this capability. True, one such construction was described in [2]...

    ESR meter in the battery tester

    This meter was not designed for very accurate measurements of ESR. It is made for rapid express analysis of capacitors. Good-bad. Calibration was performed only for the limits of sectors,although it is possible to mark the scale more accurately. My circuit is slightly different from the...

    ESR meter in the battery tester

    I already wrote that my ESR meter works at a frequency of 100 kHz. You can transfer my topic to another place, there are no problems.

    ESR meter in the battery tester

    The battery tester was chosen specifically to not use the eps tables. Green sector.0,005-0,5 Ohm corresponds to the range of capacitors 10000uF-100uF. The small sector.0.5-2 Ohm corresponds to the range of capacitors 100uF-10uF. Capacitors of small capacity fall into the red sector. The scale...
