Field practice, the stand or fall of capacitance is measured with a digital multimeter

With digital multimeter capacitance file can be easily measured the stand or fall of a capacitor. Here is the detailed measurement method. 一个47μf的电解电容,用数字万用表电容档测量其容量,显示为45。 17μF。 【 Judge capacitance method 】 The digital multimeter to capacitance range switch gears suitable range, and then insert the multimeter's red and black pens and respectively multimeter Cx insert and COM jack ( 为了拍了照竽,反反复复用带鳄鱼夹的测距试线代替表块) 懂事,然后红黑表块接种触电容性两个引脚( 年轻是测量电解电容,可做分极性) , if the value of the multimeter displays and capacitance of the nominal value is close to, 一般以逸有5% ~ 10%的误差) ,则显示该电容是良性的。 ▲万电容档测量一个标称值为用表。 1μf / 630 v的cbb电容,实时显示容量为。 1037μF。 ▲对于击穿损失坏的电容,其两个引脚之间的电阻很小,用于此时万表,电容档测量仪表会显示“1”,即溢出,已故驻测量电容时,若万用表量程开关位置未泼配合,但仪表显示为“1”,则政府该电容很可能击穿坏或漏电损失太大( 此时可用电阻档万用表测量其阻等于,进行确认是与否损失答) 。 ▲对于长时间放置的电解电容,有些电容内部电解质会逐渐乾枯,使其容量变得强人,已故驻测量电解电容时,若显示的容量显著低于其标称值,则该电容一般不宜使用。 上图所示为一个放了几年的100μf的电解电容,实量测其容仅有54岁。 08μF。
