Use an analog multimeter to measure
capacitance by connecting t he t wo
ends of capacitor with the multim eter
rod connecto r . If the pointer swi ng
to the direction of smaller
resistance ,and then turn back to
the dir ectio n of “0” slowly, it means
that the capacitor is ok . If not , it
mea ns that t he capa citor i s
