How to test efficiency of the condenser

Check the condenser, this is a very simple action, which require minimal knowledge of the meter and a basic knowledge of a soldering iron. Do you still doubt their abilities, then this material will help validate effortlessly.

Preparing to verify

At the time of absolutely any work at the forefront of the security costs, and since we have gathered to check the capacitor, it is first necessary to defuse. Of course you can do it very simple screwdriver, but I recommend you do discharge the capacitors through a resistor

Take absolutely any of your existing resistances and just solder it to small pieces of wire, all discharging capacitor ready. But after you are discharged Conder, we proceed to the verification activities.

Important. Check capacitor soldered to the circuit is impossible. Because you will receive incorrect data. Therefore, before testing it should vypayat.

visual inspection

Any checks should start with a visual inspection, because sometimes, at a glance, to understand - the item is defective. Look closely at the upper part of the "Conder", there is "weak" area in the form of a crosshair, which protects part of the explosion. If you see there is swelling or stains, it means that the capacitor is definitely spoiled.

Just check the board near the landing site "Conder", there you do not see signs of darkening and destroying the tracks.

Thus, the outward signs of failure not, then check the next with the help of instruments.

Measuring devices

So you vypayat capacitor and prepared a screening device, but do not hurry to do it. First we need to know what type of cell in front of us: a polar or non-polar. After all, if we are on the polar capacitor messed plus-minus, this "Conder", you can safely throw in the trash, even though he had previously been fully functional.

Therefore, carefully inspect it and if we do not see any symbols around the legs of the "+", "-" strip or check mark, then we nonpolar Conder and he does not care on how you move the to him ends. And if you find a symbol, then observe the correct connection of wires.

resistance check

We expose a dial on the multimeter and summing up the ends of the capacitor according to the polarity. Initially, you should see a small value, and signified it will gradually grow and eventually reach a value of "1". This means that the item is defective.

In the case, if the device is almost immediately showed a "1" means that breakage within the product. A zero indicators suggest a short circuit in the barrel. In this and in the version Conder defective.

The non-polar capacitor as check follows. On tseshka expose parameter 2 MOhm and look at the device. In the case of serviceable capacitor the display shows a value greater than two, saw the value is less, Conder defective.

Important. All these manipulations are suitable only for capacitors greater than 0.25 uF.

check capacity

Check capacity is also very simple. Carefully inspect the item and we find there the required amount. Then, on the multimeter expose the measuring range and in case, if the design verification device allows capacitor inserted as shown in Figure

If this nest not, just check the probes

In this case, yes display you should see the number as close as possible to the nominal value. If it differs, then "Conder" broken and his throwing.

check the voltage

The same product performance, you can check the voltage. To do this, you need to podsoedenit capacitor power supply with a low initial voltage.

For example, if you have a capacitor rated at 25 volts, the power source is needed at 9 volts (crown or multimeter itself is fine). Thus, the probes according to the polarity, continuity with pre-exposed, charges the capacitor.

Thereafter tseshka to switch the voltage measurement mode and look. Initially, the same time, you should see the number as close as possible to the nominal figures. If not, Conder defective.

Important. Valid data will be only at the beginning of the measurement, then a barrel will start to discharge, and the numbers tend to zero, this is normal.

Here are the main ways to check the performance of the capacitor, as you can see, nothing complicated about it. Thanks for attention.
