Performance Characteristics

1.Fixed current output (10mA-10A totaling 7 ranges);automatic current output (0.03-10A the optimal current is set automatically based on the resistance of the test product).

2.Wide measuring range (0Ω-20KΩ); able to measure the inductive DC resistance of transformers, mutual inductors, etc.

3.Functions of single channel measurement, YN three-phase simultaneous measurement, YN three-phase compensation simultaneous measurement (including O-phase resistance), automatic YND11 transformer magnetic, YN three-phase selection measurement, D/Y three-phase selection measurement,etc., and can calculate three-phase resistance balance rate automatically.

4.Function of auxiliary judgment of data stabilization. Automatically calculate the percentage of 5′′, 15′′ or 30′′ resistance deviation, accurately judge the readability of data, and prevent misreading of data.

5.Temperature conversion according to test product materials (copper, aluminum), for convenience of comparison with historical data

6.Transformer demagnetizing function; able to effectively reduce transformer remanence

7.Functions such as perpetual calendar, storage of 100 sets of data, Chinese and English interface selection, etc.; no data loss after shutdown. The instrument is provided with micro-printer and “U disk” interfaces.

8.6" color touch LCD

9.Dual RS485 communication interfaces for convenience of inter-device cascading. In cooperation with the control software of the upper computer, the instrument can achieve remote control and measurement. The instrument can be fitted with an optional built-in  module to achieve  wireless communication.

10.Audible discharging alarm, and clear discharging indication to reduce misoperation

11.The instrument is protected from wrong connection of AC380V power; after the protection function is activated, an audible alarm is given to reduce the damage caused by misoperation to the instrument. The instrument also has perfect counter emf protection function and strong arc discharge resistance.

12.The instrument has features such as dust prevention, shock prevention, moisture prevention, high measuring accuracy, good stability and repeatability, high portability, etc.
