Adopting the third generation constant current source technology, the maximum output current can reach 50A (40A), the output voltage can reach 24V, built-in channel conversion matrix. By one cable connection, the instrument can finish  DC resistance testing items including three-phase simultaneous test, phase by phase test, magnetic assistance test and single phase test.

Function Introduction

● The output current can be set and also can be selected as per the resistance of the tested product automaticly.

● Having the three-phase simultaneous testing and phase by phase testing function, and calculate the resistance balance rate of the three phases automaticly.

● Measuring range: 020kΩ, the instrument can measure the DC resistance of the inductive products such as the transformers and instrument transformers.

● Auxiliary judgment of data stabilizing function. Automatically calculate the percentage deviation of resistance value of 5s, 15s and 30s, accurately determine the reliability of data, and prevent misreading data.

● The temperature conversion can be made according to the material(Copper/Aluminum) of the tested products, so that it is convenient to compare with the historical data.

● With transformer demagnetization function, it can reduce residual magnetism of transformer.

● With a permanent calendar, 99 sets of data storage, Chinese and English interface selection function, power failure without data loosing, mini printer and U disk interface.

● With 6 inch color touch LCD display screen.

● Dual RS485 (RS232) communication interface, with PC control software, the instrument can realize remote control measuring.

● With the discharging alarm by sound and the discharging indicating clearly function, the misoperation can be reduced.

● With AC380V misconnection protection function,perfect back EMF protection function and anti-arcing function.

● It has the features of dustproof, shockproof, moistureproof, high precision, good repeatability and portability.
