Resistor manufacturers, the detection of resistors


    Resistor, braking resistor In order to improve the measurement accuracy, the scale should be chosen according to the nominal value of the resistor. Due to the non-linearity of the ohmic detent, the middle part of the graduation is more elaborate. Therefore, the indicator value should fall as far as possible to the middle of the scale, that is, the range of 2080 radians from the beginning of full scale to make the measurement more accurate. According to the resistance error level is different. ± 5, ± 10 or ± 20 tolerances allowed between reading and nominal resistance respectively. If you do not match the error range exceeds the error that the value of the variable. B 0 2 attention to the test, especially when measuring the resistance of more than a few dozen kΩ Do not touch the conductive part of the test leads and resistors The resistance to be tested Welding from the circuit at least to open a welding head to avoid the other Component impact on the test caused by measurement error Color ring resistance of the resistance Although the color ring logo to determine but in use it is best to use a multimeter to test the actual resistance.
