English/Spanish Handy Transformer Ratio Tester 3 Phase Turns Ratio Group Meter

Product Overview：This new JH2711 Handheld Transformer Tatio Tester TTR Metet has a host that is easy to measure at high altitudes, more convenient to use, and has more stable functions. The host comes with a printer that can print data at any time.For the power system, transformers are the core equipment in the system, so the long-term and reliable operation of transformers will be related to the stability and reliability of the entire system. Before the newly installed transformer is put into operation and in accordance with the preventive testing regulations of State Grid, it is required to conduct regular turns ratio or voltage ratio tests on the operating transformer. The traditional variable ratio bridge operation is cumbersome, the reading is not intuitive, and necessary conversions need to be made. The test result is only the value of one phase change ratio. This transformer ratio tester overcomes the shortcomings of traditional ratio bridge testing. The screen adopts a large high-resolution LCD display screen, which is convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and can complete three-phase ratio testing in one go. The testing speed is fast and the accuracy is high. Product Features: ​ 1. The three-phase CNC sine inverter power supply output has soft start and soft stop functions, so the testing speed is fast and the accuracy is high.2.

The "Measurement" and "Calibration" interfaces also have sub-interfaces. By default, it will enter the main measurement interface when it turns on. – It can easily measure the impedance of about 1mΩ. For example, a wire of 1cm generally has about 6mΩ. – The impedance of 300MΩ can be easily measured, and the actual measurement is 20GΩ. See the pictures below for details. The LCR bridges on the market basically cannot measure such a large impedance. Package Included: – 1 x Set of LCR Meter Note: – Components and other items pictured are not included, for demonstration purposes only. Thank you for your understanding! Precautions: 1. In order to ensure the accuracy of measurement and calibration, please warm up the product for at least 5 minutes before measuring. Especially when doing calibration, it is best to warm up for more than 20 minutes. After warming up, calibration parameters can be more accurate. 2. When powered by a battery, the internal noise of the product is the smallest, so it is recommended to measure under battery power. Especially when doing the calibration operation, it is strongly recommended to do it under battery power supply. When a charger is connected, if the quality of your charger is not good, a certain amount of noise will be generated. 3. Do not connect to a computer's USB charging port for charging. The signal from the USB port will seriously interfere with the working state of the product and cause serious inaccuracy in product measurement. 4. Please try to use better quality fixtures. 5. Before measurement and calibration, please make sure that there is no strong interference signal around, so as not to cause inaccurate measurement results due to interference. 6. When the battery is low, please charge it in time to avoid long-term lack of power. 7. The interface is BNC. Since copper has relatively lower strength than other metals, please try to protect it carefully to avoid falling and bumping damage. 8. In the case of strong interference, unconventional operation, and abnormal software unknown bugs, a crash may occur (the power may be consumed after the crash, until the battery is exhausted). At this time, please directly press the "RESET" hole to reset the product to avoid damage to the battery. If the battery is exhausted and the battery is extremely short of power, the current will be large during charging, and the charger with a small power supply current will have short-circuit protection, but please continue to charge until the battery can be charged normally. 9. When the power is lower than 15%, it will not be able to turn on; when the power is very low, the system will automatically shut down. Please charge in time. 10. When measuring large capacitances (uF level), the "electrolysis" item is more accurate than the "capacitance" item. 11. The device under test cannot be charged, especially the energy storage device (such as electrolytic capacitor), it must be discharged before testing, otherwise it may It will damage the instrument. 12. When measuring milliohm-level devices, if more accurate is required, please perform short-circuit calibration again under the same conditions as the frequency to be measured. 13. When calibrating, try to stay away from the surrounding environment interference, preferably away from the mains, such as wires and sockets. When measuring, use the battery of the instrument to work, do not plug in the USB port for power supply.
