Introduction

1. The instrument can use an Android phone or tablet, follow the WeChat official account, download a special APP, control the instrument through the special software, and store and upload test data for easy reference.
2. The maximum output voltage of the instrument is 24V, which is convenient for selecting a larger test current when the resistance is high, and improving the test speed
3. The instrument adopts brand-new power supply technology, with multiple current gears and wide measurement range. The current can be automatically selected according to the load, which is suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.
4. It has multiple protection functions such as back-EMF impact, interruption and power failure during the test, and power supply overheating, which can reliably protect the instrument from back-EMF impact and synchronous sound alarm.
5. With any temperature conversion function of copper and aluminum materials, touch input of any winding temperature and converted temperature.
6. Intelligent power management technology, the instrument always works in the minimum power state, which effectively saves energy and reduces heat generation.
7. Seven-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English.
8. The instrument comes with a perpetual calendar clock and power-down storage, which can store 1000 sets of test data, which can be consulted at any time.
9. The instrument has Bluetooth communication, RS232 communication and USB interface for computer communication and U disk data storage.
10. Comes with a panel-type micro printer, which can print the measurement results in Chinese.
