Professional Instrument Equipment and Testing Solution Supplier - JETYOO Industrial&Jianyou (Shanghai) Measuring Instrument Co., Ltd, a former Agilent product technical support engineer-Jian JETKEITHLEY Product Technology Application Engineer-RongyooA trade agency co founded in 2011 with a focus on technical support, aiming to break through the old and establish a new one! Fill the gap of most imported instrument and equipment manufacturers only setting up sales points in China, with weak or no technical support, and agent distributors only specializing in sales, not professional in pre-sales technical Q&A/testing plans, and not professional in after-sales training/maintenance calibration. Our technical sales engineers all have a bachelor's degree or above and over 10 years of experience in the testing industry. With our advanced and unique business philosophy, we specialize in providing instruments and equipment, testing solutions, technical training, and maintenance and measurement services to Chinese users. We are a leading company in the East China region of ShanghaiTechnology orientedA comprehensive service provider for instruments and equipment.

MICROTEST 7720 Multi channel Coil Interturn Short Circuit TesterThe application of coil products is very extensive, including transformers, motors, generators, ignition coils for automobiles and locomotives, relays, electromagnets, filters, and various inductors and coils. Almost all electronic and electrical products use it. However, coil components cannot be produced automatically like general electronic components in terms of manufacturing processes, and existing enameled wires cannot achieve ideal quality assurance in the manufacturing process, so it is inevitable that adverse situations will occur during the manufacturing process. 7720 is an 8-channel pulse voltage (programmable) 5000V coil turn to turn short circuit tester that can provide waveform comparison functions such as area ratio, area difference ratio, voltage time difference, etc. It can also use a cursor to select the comparison range, thus covering the waveform differences caused by the differences in electrical characteristics between various components and detecting defective products. Due to the ability to provide different resonance modes for selection, it can be applied to various coil products, ensuring the quality of line of sight coil productsgoodInstruments.
