How do you measure the capacitance with a multimeter?
Choose a good range needle
1, take out the multimeter first to find the capacitance file area, the capacitance file area on the multimeter will generally be marked with F tips.
2, and then determine whether the meter needle has not inserted the wrong, whether it needs to be replaced, for example, the following multimeter will need to change the two pens.
3, select the capacitance range, if you do not know the size of the capacitance to be measured can choose the maximum range.
Put the meter pens on both ends of the capacitor
Capacitance in the measurement before remember to discharge, discharge method is also very simple, the capacitance of the two ends of the short connection on it, the capacity of the capacitance of the best series of a resistor, the following as long as the pen connected to the capacitance of the two ends on it, remember not to touch the two electrodes at the same time with your hand, otherwise the measurement results are not allowed, if the measurement is smooth, then you can read out the capacitance capacity directly on the display.
How to roughly measure capacitor capacity with a pointer multimeter. Prepare a number of capacitors with small error and common capacity, such as 0.1uf, 0.47uf, 1uf, 2.2uf, 4.7uf, 10uf, ....... Respectively with 1K (or 10K) resistance gear on the two legs of the capacitor alternately for measurement, and record the needle swing amplitude, to create a control table. Later, when measuring the capacitor capacity, the capacitor from the circuit board welded down, with a pointer multimeter alternately measured, according to the amplitude of the pointer swing, compared with the control table, you can roughly know the capacity of the capacitor.
