Can a multimeter measure capacitance? How to use a multimeter to measure capacitance
1. Pointer multimeter detects capacitance
1.1. Detection of fixed capacitance
(1) Detection of fixed capacitance with a capacity above 0.01 pF Adjust the pointer multimeter to the R×10k ohm block, and perform ohm adjustment to zero, then use the red and black test pens of the multimeter to touch the two pins of the capacitor respectively, and observe the pointer of the multimeter changes, as shown in Figure 1. If the pointer of the multimeter swings slightly to the right when the test leads are turned on, and then returns to infinity. After changing the test leads, measure again, and the pointer also swings to the right and then returns to infinity, then it can be judged that the capacitance is normal; , the pointer of the multimeter swings to the vicinity of "0", it can be judged that the capacitor is broken down or seriously leaking; If the pointer does not swing, it can be judged that the capacitor is open.
(2) Detection of fixed capacitors with a capacity less than 0.01 pF When detecting small capacitors below 10pF, the capacitance is too small, so use a multimeter to measure, only to check whether there is leakage, internal short circuit or breakdown phenomenon: choose the Multimeter R×10k block, connect the two test leads to the two pins of the capacitor at will, and the resistance value should be infinite. If the measured resistance value is zero, it can be judged that the capacitor is damaged by leakage or internal breakdown.
