## The Test Methods and Experiences of 8 Resistors

1. Fixed Resistor Testing.

A. Connect the two probes(regardless of positive and negative) to the pins of resistors respecially, the actual resistance value will be measured. In order to improve the measurement accuracy, the measured resistance should be based on the size of the nominal value to select the range. As the scale of the nonlinear Ohm's block, dividing it in the middle of a more refined, pointer indicates the value should be possible to scale fell on the middle position, that is the start of full scale of 20% to 80% within the arc to make the measurements more accurate. According to a different level of resistance error. Reading between the nominal resistance were allowed ± 5%, ± 10% or ± 20% error. If we do not match, beyond the error range, then the resistance value change the value.

B. Note: When you are testing, particularly in the resistance measured over tens of kΩ resistor, hands do not touch the probe and resistance of the conductive part; be detected in the welding of the resistance from the circuit down, at least open a welding head, in order to avoid circuit The impact on other components of the test, resulting in measurement residual; the resistance value of color ring resistor can be able to determined by color ring marks, but is best to test the actual resistance using a multimeter.

2. Cement Resistance Testing.

Detection of resistance of cement and precautions to ordinary fixed resistor with the same test.

3. Fuse Resistors Test.

In the circuit, when the fuse resistor fuse open, you can make judgments based on experience: If it is found fuse resistors or charred black surface, it can be concluded that the overload rating of the current through it many times over due; If the surface without any trace of the open, it indicates that the current flow is equal to or just greater than the rated fuse value of sales. For the surface without any trace of the fuse resistor to judge good or bad, can make use of the multimeter to measure the R × 1 block, to ensure accurate measurement, it should fuse resistors from the circuit on one end of the next weld. If the measured resistance is infinite, then the fuse has failed open circuit resistor, if the measured resistance falls far short of the nominal value, that value of resistance change, we should not be used. In the maintenance of practice found that a small number of resistors in the circuit fuse is short breakdown phenomenon, attention should also be detected.

4. Potentiometer Detection.

Check the potentiometer, the first to turn the rotating handle, turn handle to see whether the smooth rotation, the switch is flexible, switch-pass, short "clicks" is crisp, and listen to the potentiometer and the resistance of the contact point within the body of friction sound, if any "imperfections" sound, indicating poor quality. Test with a multimeter, the first based on the size of the measured resistance of the potentiometer, the appropriate choice of a good multimeter resistance gear, and then according to the following method for testing.

A. Measured with a multimeter's ohm block "1" "2" at both ends, the reading should be nominal for the potentiometer resistance, such as the meter pointer does not move a lot of difference, or resistance, it indicates that the potentiometer is damaged.

B. Detect whether the activities of the potentiometer arm and the resistance of film contact is good or not. The ohm meter test block with "1" "2" ("2" "3") ends of the potentiometer shaft counterclockwise rotation to close the "off" position, when the resistance value as possible. Handle clockwise rotation axis and then slowly, the resistance value should be increased gradually, the pointer in the header should be a smooth move. When the spin axis of the handle to the extreme position of "3", the resistance should be close to the nominal value of the potentiometer. If the multimeter pointer handle potentiometer shaft rotation in the process of jumps, indicating active fault contacts are bad.

5. Positive Temperature Coefficient Thermistor (PTC) Detection.

When detecting, with a multimeter R × 1 block, concrete and two-step operation:

A. Room Temperature Testing (room temperature close to 25 ℃): the two probes touch the two pins PTC thermistors measure the actual resistance, and with the relative ratio of the nominal resistance, the difference between the two is the normal within the ± 2Ω. If the nominal resistance and the resistance of the actual difference is too large, then the performance is bad or damaged.

B. Heating Test: at room temperature, on the basis of the tests are normal, then a second step tests - heat detection, to a heat source (such as electric iron) near the PTC thermistor to its heating, while monitoring the resistance with a multimeter if the value increases with increasing temperature, and if so, that the normal thermal resistance, if resistance did not change, indicating that its performance became inferior and can not be used. Careful not to heat with the PTC thermistor by too close or direct contact with the thermistor in order to prevent their ruined.

6. Negative Temperature Coefficient Thermistor (NTC) Testing.

(1) Measured nominal resistance value Rt NTC thermistor with a multimeter measuring methods and measuring the same way as ordinary fixed resistor, which according to the nominal resistance of NTC thermistor select the appropriate power block can be directly measured actual Rt value. But NTC thermistor is sensitive to temperature, so the test should note the following:

A. Rt is the manufacturer at an ambient temperature measured at 25 ℃, so the Rt measured with a multimeter when the ambient temperature should also be close to 25 ℃, in order to ensure the credibility of the test.

B. Measurement of power shall not exceed the specified value, so that the current measurement error caused by thermal effects.

C. It is operating correctly. Test, and hold your hands to prevent the body temperature of the test impact.

(2) Estimate the temperature coefficient "at"

First measured the value of t1 resistance Rt1 at room temperature, then electric soldering iron for heat, close to the thermistor Rt, measure the resistance RT2, also measured with a thermometer at this time the surface of the thermistor RT and then calculated the average temperature t2.

7. Varistor Testing.

R × 1k with a multimeter to measure the varistor block between the two pins is, the reverse insulation resistance, are infinite, otherwise, that leakage current. If the measured resistance is very small, indicating varistor is damaged, can not be used.

8. Photosensitive Resistance Testing.

A. With a black piece of paper to cover the window light sensitive resistor, when the multimeter pointer remained fixed, the resistance approaches infinity. This value shows the bigger the better performance of photosensitive resistance. If this value is very small or close to zero, indicating photoresistor has burn damage, can not continue to use.

B. Will be a light transmittance of the window aligned photosensitive resistance, when the multimeter pointer swing should be more substantial, more resistance was significantly reduced. The smaller this value the better the performance that photosensitive resistance. If this value is large or even infinite, indicating that the resistance of the internal open-photosensitive damage, can no longer continue.

C. The photosensitive resistor light window light rays aligned with the black pieces of paper on top of the window shade photoresistors shaking, it stopped by the light, this time with the black pieces of paper multimeter pointer should be shaking and side to side. If the meter pointer position does not always stop with the paper in a rock and swing, indicating resistance of the photosensitive photosensitive materials have been damaged.
