How to Measure A Capasitor, to Know the Condition Good or Broken


How to measure a capacitor to find out the condition of the capacitor is still good or has it been damaged or broken?

Actually, to find out whether the condition of a capacitor is still good or has been damaged is not difficult, The condition of a capacitor can be known by using a special tool called the Capasitance Meter, but if we do not have a measuring device, it can also be measured using a multi-function measuring instrument called a Multi-tester or Multi-meter.

Many capacitors we encounter in everyday life, and are usually installed on various electrical equipment that we use, such as electric water pumps, fans, washing machines, air conditioners and so on.

What is the function of capacitors?
The capacitor is an electronic component that can function as a storage device for a momentary electric charge, Like for example a capacitor in a water pump motor, the capacitor serves to provide a momentary surge of electrical voltage that flows on the auxiliary coil, so that there is a difference in the magnetic field between the main coil and the auxiliary coil, so that the pump motor can spin itself.

Have you ever experienced a water pump that you have when you turn it on it doesn't want to spin, but after we turn it on its axis then the water pump can rotate normally, what's the cause?

If you have experienced this before, this indicates that the capacitor on the water pump motor is not working or broken (damaged).

However, to ascertain whether the Capacitor is really damaged or still in good condition, it can be measured using Multitester or analog multi meter.

On this occasion we will share about how to measure capacitors using Analog Multi-Meter, even though actual capacitor measurements can also be done with digital multitester, or with meter capacitance, but because multitester measuring devices are usually easier to get than other measuring devices, and most widely used to measure capacitors.

How to measure capacitors with analog Multi-Mester
  1. Prepare a measuring device (Analog Multi Meter)
  2. Adjust the position of the selector in the Ohm-meter position (to measure the resistance value)
  3. Make sure the Multitester condition that you are using is still good and functioning properly
  4. Prepare a capacitor that you will measure, and make sure the capacitor is no longer connected from the cables.
  5. Connect the test probe at each capacitor terminal
  6. See the measurement results on the multitester

Read the measurement results
  • If the multimeter pointer moves from left to right and a few moments later the pointer goes back to its original position, this indicates that the capacitor is still good.
  • If the multimeter pointer moves from left to right but does not return to its original position, this indicates that the capacitor is not good (damaged).
  • If the multimeter needle does not move at all, try moving the position of the measuring needle from positive to negative or vice versa.
  • If the position is reversed but the measuring needle is still not moving, this indicates that the capacitor is indeed damaged
  • But if after the position of the measuring needle is reversed and the multitester pointer moves from left to right and a few moments later the pointer back to its original position indicates that the capacitor is still good.

After we know how to measure capacitors to find out whether the condition is still good or has been damaged, it is expected that we can repair it ourselves if there are electrical equipment in our house that is damaged.

If the electrical equipment you use at home, such as a fan, an electric water pump, it cannot rotate even though it has been turned on, and if it is assisted to rotate for a moment, it can rotate normally again, this means there is a problem with the capacitor, by replacing the capacitor with a good one, device electric fan or water pump will function normally again.
