Reading of color ring resistance
The resistance value ring color ring of the resistance value of 1/8 wattawa resistance. There are three or three or four -colored loops on the resistance resistance. Near close to the resistance end of the electronics resistance end, the color ring, as shown in the first position below, the second digital number, the second second, the second, the second digit number digital digital numbers Digital number fourth color ring. Domestic or television TVs include color ring resistance resistance resistance, its resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance resist During the process, it is colorful, read, use, and use it for easy use.
The detection method of the resistor
The basic skills of the item, how to basic the basic skills and basic parameter parameters, determine the parameter parameters, judge the correlation, judge the normal normal, normal normal, normal, normal, normal, normal, normal, normal, normal, normal, and normal, or not. For example, for speaking
One, test and ::
1. Photo -sensitive resistance detection and detection
A A A A covers the light sensitivity and light transmittance. At this time, the basic basis is basically maintained. Essence Essence
B The large -resistant light window window window window window window window pointer pointer is large. Essence Essence
C incident the light into the light light, and use the upper part of the upper part of the shading window of the paper resistor to swing in the position without paper, which shows that the light -sensitive material material of the swinging resistor is swinging the resistor.
2. Negative temperature thermistor resistance detection and testing
a A A measured the resistance value of the resistance with measurement measurement measurement measurement and measurement thermistor resistance method to measure the same, the same, the same the same the same the same, the same the same, the same the same, the same the same, the same the same, the same the same, the same the same, the same, the sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitivity sensitive sensitive sensitivity sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive sensitive敏感敏感：art是是几点点点点点点点点点几以下以下以下生产生产生产生产生产生产生产厂家厂家在环境环境温度温度温度温度25℃为为为为为为为为为为为为为为为为为℃℃℃℃℃℃℃℃℃℃℃ ℃进行，以测试可信度信度信度功率超过规定值规定值规定值规定值规定值测试产生影响。

Essence Essence R × 1K transmission measurement transmission measurement gear transmission measurement volume gear test measurement volume -sensitive electrical electrical electrical resistance electrical electrical resistance electrical electrical resistance electrical resistance electrical resistance electrical resistance electrical resistance of voltage voltage voltage resistance The resistance resistance of the positive resistance resistance between between is small, indicating that the voltage resistance is damaged and does not damage
3. Positive temperature heat -sensitive resistance detection and testing
During the test, use the table R × 1 gear
A room temperature; the p) contact contact value resistance resistance value resistance value resistance value resistance value resistance value, and the resistance value of the resistance value, and the relatively comparison ratio of the nominal nominal nominal ratio Comparison ratio is relatively comparison with relatively comparison ratio, and the performance is poor. Essence Essence

It shows that the performance becomes bad, and the non -performance becomes inferior to inferiority and inferiority.
4. Cement resistance. The precautions of the cement resistance method to detect the ordinary fixed resistance exactly the same.
5. Detection of potentiometer
During the inspection, first rotate, look at the smoothness, switching, flexible switch, flexible switching and switching, such as "rustling", indicating that the sound is always useful, test test test test, test electricity testing, testing electricity testing from time to time, testing electricity testing electricity testing. The size of the potentiometer size
A A uses a universal test block to test "1", "2", and its ends. Resisting value resistance resistance value resistance resistance value resistance value resistance value
B to detect the contact between the arm of the potentiometer and the resistance tablet. Essence Use a table Om Ohm file test file measurement file measurement file measurement file measurement file measurement file measurement test file measurement file measurement test file measurement The test file measurement file measurement stall measurement test stall measurement stall measurement stall measurement file measurement stalls ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,? ,,,,,,,,,,, the resistance value during testing. The re -shaft handle shaft handle, the electricity is slow, the electricity should be gradually, the head of the head is enlarged, the head of the head is enlarged, the head of the head and the head is increased, and the middle and middle shaft handle of the head head and the middle and middle shaft handle handle Axial handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle shaft handle The shaft handle shaft handle shaft handle handle is nominated for the pointer potentiometer shaft handle of the universal meter.
6. Detection and testing of fuse electricity
Among them, when the electric melting is broken, the road can be opened: if you verify the judgment: if you make a discovery of the surface of the fuse and the fuse of the resistor resistor resistor surface or burning, burning, scorching, can be concluded; The over -current is equal to or slightly greater than greater than that of its rated melting melting value. For those who have no traces on the surface surface, in order to ensure, if the measurement is tested under the welding of the electricity circuit, it is infinite and large, indicating that the change of the value, and the discovery of it will not be found. It was found that it was found that the fuse and fuse resistor resistor circuit was cut through and penetrated short -circuit short circuit
7. Fixed resistor detection and detection
A A can be actual and actual. In order to improve the measurement and measurement accuracy, accuracy accuracy accuracy accuracy accuracy should be based on the measured resistance. ± 5 ± 5 ± 10 ± 10 ± 20 ± 20 % ± 20 % % % % % of them are not nobody, no no no, no no matching match, matching, matching, matching and matching.
B Note: Test testing, especially the effect of testing more than tens of or more, causing measurement; although the resistance resistance value can be used to determine
