With a Multimeter How to Test Components

In general, the mechanic when testing electronic components using multimeter aid in the work. With these tools can be known whether or not a component. Testing before the assembly is very important because the components are installed / soldered and connected in its original good condition. As for the beginner, testing with a multimeter can be done. But not all know the ropes.

1. Test the condenser

The trick is with the following steps below:

1. At first, switch the multimeter rotated upward. Arrow up precisely R x Ohm
2. Calibration until the needle multimeter indicates zero just as the two plug (+) and plug (-) is connected. Rotate Adjustment to adjust.
3. Connect the plug (-) negative pole with foot condenser, while the plug (+) with positive foot condenser. See the needle. If bergerrak and did not return mean component is still good. If it moves and back but not like the original position means the component is damaged. And if the needle does not move at all likely drop out.

2. Testing Resistor / Detainees Remain

Although these components do not have a negative and positive poles with a multimeter but we will test the quality. Not closing the possibility of damage caused by several factors, one of them due to fire / short circuit currents could not help it withstand greater than its value.

To test it with a multimeter we can flip through the resistor leg or otherwise turning the plug (+) and plug (-).

Step-by-step examination of the resistor:

1. Rotate the switch to the position of R x Ohm.
2. Calibration with a connecting plug (+) and plug (-). Then play the tuner until the needle points to zero (0). Or rotary control to adjust adjusment.
3. After that we connect pencolok (+) on one leg resistors, as well as plug in (-) on the other foot.
4. Note the needle. Is it moving full or vice versa if it moves and does not return meaningful components are still good. Otherwise the scale does not move the needle means the resistor is damaged.
5. Resistor is still good components can also be assessed with the same or not the value of resistor components are listed on the color bracelets with measurements via a multimeter.

3. Testing the variable condenser

Testing the variable condenser is not intended to determine the level of leakage. This is because he is not made of materials like used in the manufacture elco, ceramic capacitors and others.

The purpose of this testing was to determine the relationship / direct contact between the rotor and stator. If both are connected it can not be used because of short circuit causing a rustling sound on the radio. Usually Varco ang thus can be determined by Varco twisting to get the signal (wave) and the rustling sound of a sharper than the sound-emitting jets.

To determine the level of short circuit in a Varco is to:

• First rotate the switch a multimeter on position R x Ohm or 1x and K. Calibration as usual.
• Connect the plug (-) and plug (+) on each foot.
• Play rotornya. If the needle does not move at all mean Varco in good condition. If the twitching is the case then the component directly contacts / shorted.

4. Testing Diodes

This component has a pair of legs which each negative and positive pole. Therefore, in the later test should be done properly and carefully. The purpose of testing this tool is to determine the level of damage caused by several things. In the diode that had been used in a circuit is usually caused by the amount of pressure flow and is unable to hold and converted to DC.

Method of testing:

1. Switch is rotated to the position of an ohmmeter, 1x and Calibration.
2. Connect the plug (-) with negative leg (anode) and plug (+) with positive leg (cathode).
3. Then move pencolok (-) at the foot of the anode and plug (+) at the foot of the cathode. When the needle moving means the diode is damaged. If instead (not moving) then the diode is in good condition.

5. transformer Testing

Transformer when we buy our need and obligation to check whether it is still good and functioning. Due to the transformer is usually not given a warranty if damaged after purchase. It is possible the termination of the coil / coil secondary or primary.

Steps:

• Multimeter rotary switch to position Ohm 1x. Calibration.
• Connect the plug (-) with one foot in the primary coil, plug (+) on the other foot in the primary winding. If the needle moves then the transformer is in good condition.
• At the secondary windings are doing the same thing. If the multimeter needle moving the transformer is in good condition. Difference in value equal to the difference voltage marked on the transformer.
• Put the plug in (-) or plug (+) to one foot in the primary windings and then plug the other into the secondary winding. If the needle does not move then the transformer is in good condition, indicating the absence of shorted primary winding of the transformer with the secondary body. Do the opposite.
• The last step, put the plug (-) or plug (+) to one foot in the primary or secondary windings and then plug the other to the fastener plate coil in the middle. If the needle does not move then the transformer is in good condition, indicating the absence of shorted windings in the transformer body.
