    Lutron DM-9023 Capacitance Meter

    About a month ago, I bought a Lutron DM-9023 Capacitance Meter, since I want to go through my stock of used electrolytic capacitors.
    It goes down to .1pF units, and can measure up to 20,000uF (it is not likely that I will ever measure a capacitor which is over 10,000uF or even over 20,000uF).
    Since Lutron (Taiwan) has been making quality test equipment for over 30 years, I can trust the accuracy of this particular equipment.
    With this equipment, I found a number of off-brand (Jun Fu, JP etc.) 200/250V electrolytic pairs from computer power supplies were way out of tolerance and I got rid of them.
    I even got rid of two known-brand 400V units which had very little capacitance when measured compared to the capacitor label.
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.
Working...
