Baijian can provide various equipment testing services such as consumer material testing according to corresponding testing standards, and can also design solutions based on customer needs to provide non-standard testing services for customers. Baijian Testing is a comprehensive third-party testing agency that provides customers with one-stop testing services and green solutions. If you have testing needs, please feel free to inquire at any time. Testing cycle: 7-15 working days to issue testing equipment testing reports. Testing fee: Free initial testing, quoted based on customer testing needs and experimental complexity. Sample size: The specific sample size needs to be determined based on the customer's testing project, and you can consult an engineer. Connect two probes (regardless of positive or negative) to the pins at both ends of the resistor to measure the actual resistance value. In order to improve measurement accuracy, the range should be selected based on the nominal value of the measured resistance. Due to the nonlinear relationship of the ohmic scale, the middle section of the scale is relatively fine. Therefore, the pointer should be positioned as close as possible to the middle section of the scale, which is within the range of 20% -80% radians from the beginning of the full scale, in order to make the measurement more accurate. Depending on the level of resistance error. An error of ± 5%, ± 10%, or ± 20% is allowed between the reading and the nominal resistance value, respectively. If it does not match and exceeds the error range, it indicates that the resistance value has changed. Attention: During testing, especially when measuring resistance values above tens of k Ω, do not touch the conductive parts of the probe and resistance with your hands; The tested resistance should be soldered off from the circuit, at least one head should be soldered open to prevent other components in the circuit from affecting the test and causing measurement errors; Although the resistance value of the color ring resistor can be determined by the color ring symbol, it is best to use a multimeter to test its actual resistance value when using it
