ZY9986 (3A) Relay Contact Resistance SorterIt is a desktop digital resistance sorter suitable for measuring and sorting various DC resistance components in mass production or assembly line operations. Not only can it correctly display the resistance data of the tested components, but it can also quickly determine whether the components are qualified and whether they exceed the positive and negative tolerances, greatly improving work efficiency. The test current is small, making it particularly suitable for detecting various types of DC resistors with certain current limiting requirements, such as platinum thermistors, copper thermistors, thermistors, PTC ceramic thermistors, and various resistance type alloy wires. The upper and lower limits of the product can be set for volume, and the tone can be adjusted, making it easy for multiple instruments to be used simultaneously in the same situation. The fast sorting circuit using sound and light indicators enables fast product detection speed and high work efficiency. There are multiple specifications of instruments, each with 3 ranges, to meet the production needs of different professions. The four wire resistance measurement method avoids the influence of the conductor resistance of the measuring wire and the contact resistance between the connectors on the measurement results, resulting in high measurement accuracy and good repeatability. The instrument is equipped with a precision reference resistor, which can calibrate accuracy without the need for external standards. The product has a low price and good reliability, making it the most cost-effective testing equipment.
