Recently, after receiving after-sales service needs from customers in Shanghai, Jindian Technology immediately dispatched professional and technical personnel to the customer’s location to carry out the delivery acceptance and on-site commissioning services for the microcomputer relay protection tester purchased from our company.

　　product description

　　1. This instrument has standard four-phase voltage, three-phase current output, voltage 125V/phase, current 40A/phase. Three-phase parallel connection can reach 120A. Various tests can be performed on traditional relays and protection devices and modern computer protections;

　　2. The classic Windows XP system has its own recovery function to avoid system crashes caused by illegal shutdown or misoperation.

　　3. Equipped with ultra-thin industrial keyboard and optical mouse, which can complete various operations through keyboard or mouse just like ordinary PC.

　　4. The control board adopts DSP+FPGA structure, 16-bit DAC output, and can generate high-density sine wave of 2000 points per week for the fundamental wave, which greatly improves the quality of the waveform and the accuracy of the tester.

　　5. The high-fidelity linear power amplifier not only ensures the accuracy of small currents, but also ensures the stability of large currents.

　　6. The USB interface is used to directly communicate with the PC, without any adapter cables, which is convenient to use.

　　7. Equipped with independent dedicated DC auxiliary voltage source output, the output voltage is 110V (1A), 220V (0.6A). It can be used for relays or protection devices that require DC working power.

　　8. With software self-calibration function, it avoids opening the case to calibrate the accuracy by adjusting the potentiometer, thus greatly improving the stability of accuracy.

　　After the technicians of our company arrived at the site, they carried out a careful unpacking and acceptance of the equipment. After inspection, the appearance of the equipment was intact, there were no missing parts, and the basic acceptance was qualified. After the acceptance is completed, equipment training will be carried out immediately under the arrangement of the customer.

　　At the beginning of the training, our technical staff first introduced in detail the application fields, performance characteristics, technical parameters, test principles and other theoretical knowledge of the debugging equipment, so that customers have an overall understanding of the equipment. In combination with the product manual, the test equipment is actually operated, and the customer is guided to operate the equipment on the spot. After several hours of theoretical explanations and actual combat drills, our technical staff carefully explained and provided one-to-one on-the-spot guidance, and soon the customer could be proficient in the operation.

      　　The commissioning service was successfully completed. The customer was very satisfied with the performance of our instrument and affirmed our service and technology. In the future, Wuhan Jindian Technology will continue to provide customers with better services!
