Transformer Winding Resistance Meter
Key Function And Feature
1. The instrument can use Android phone or tablet, follow WeChat official account, download special APP, control the instrument through special software, store and upload test data for easy reference.
2. The maximum output voltage of the instrument is 24V, which facilitates the selection of a larger testing current for high resistance values and improves testing speed.
3. The instrument adopts a new power supply technology, with multiple current levels and a wide measurement range. It can automatically select the current according to the load and is suitable for measuring the DC resistance of small and medium-sized transformers and voltage transformers.
Its main business is the production, manufacture and sales of electrical equipment and testing instruments.
Key Function And Feature
1. It has multiple protection functions such as back electromotive force impact, wire breakage and power outage during testing, power overheating, etc. It can reliably protect the impact of back electromotive force on the instrument and synchronously sound an alarm.
2. Equipped with any temperature conversion function made of copper and aluminum materials, touch input of any winding temperature and conversion temperature.
3. Intelligent power management technology ensures that the instrument operates at the minimum power state, effectively saving energy and reducing heat generation.
4. Seven inch high brightness touch color LCD, clear display under strong light, full touch screen operation, and free switching between Chinese and English.
5. The instrument comes with a perpetual calendar clock and power-off storage, which can store 1000 sets of test data and can be accessed at any time.
6. The instrument has Bluetooth communication, RS232 communication, and USB interface for computer communication and USB data storage.
7. Equipped with a panel mounted micro printer, it can print measurement results in Chinese.
