Transformer Winding DC Resistance Tester

Product Description

Transformer Winding DC Resistance Tester

Product introduction
The DC resistance is the transformer's semi-finished product, finished product test, installation, commissioning test, and electric part prevention test necessary test project,the transformer coil can effectively find the device welding, connecting parts loose, missing unit, disconnection, and other manufacturing default and other hidden danger occurred after operation.
The instrument has a high degree of automation, automatic discharge functions. It is a test instrument of high precision, simple, direct way to achieve fast transformer measurement.
Product Features
1. The maximum output voltage is 24V, which makes it easier to choose a larger test current at high resistance values, increasing the test speed.
2. Adopts the new power supply technology with multiple current steps and wide measurement range, which is suitable for DC resistance measurement of large and medium-sized transformers.
3. Perfect protection functions, such as counter EMF impact, disconnection during the test, power failure, power overheating, etc. it can reliably protect the impact of counter EMF on the instrument, and synchronously sound the alarm.
4. Sound discharge alarm, clear discharge indication, less faulty operation.
5. With any temperature conversion function of copper and aluminum, touch input any winding temperature and conversion temperature.
6. Intelligent power management technology. The instrument always works with minimum power, which saves energy and reduces heat effectively.
7. 7-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English.
8. Equipped with a calendar clock and power failure data-store function, which can store 1000 sets of test data and can be reviewed at any time.
9. Equipped with RS232 (reserved interface) and USB interface (for USB storage).
10. Equipped with panel micro printer, it can print measurement results.
