Web87V Fluke multimeter measures capacitance by charging a capacitor with a known current, measuring the resulting voltage and then calculating the capacitance. Steps for measuring capacitance are: Firstly ensures that … WebA capacitor rated for 2000h at 85oC, has a life of only 500h at 105oC and only 125h at 125oC. Keep in mind, 2000h is only 83 days of 24/7 usage. Luckily, keeping the capacitors at a lower temperature extends their life in much the same way. THIS is what most designers hope to exploit to ensure a longer life. III. Excessive ripple
