Product Description
FREE DHL EXPRESS NOW! Transformer Winding Ohmmeter/Resistance Tester (JYR-40C) Controlled by The Single Chip Microcomputer/Large Output Current Upto 40A
Adopting the third generation constant current source technology, the instrument is controlled by the single chip microcomputer, the self-checking, data processing and displaying can be finished automatically, having the automatic discharging and discharging indicating function. The accuracy is high and operating easily, realizing the measuring the DC resistance of the large and medium transformers at high speed.
Function Introduction
1.Output current: 20mA~50A
2.Measuring range: 0~20kΩ, the instrument can measure the DC resistance of the inductive products such as the transformers and instrument transformers.
3.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.
4.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.
5.With transformer demagnetization function, it can reduce residual magnetism of transformer.
6.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.
7.With 6 inch color touch LCD display screen.
8.Dual RS485 (RS232) communication interface, with PC control software, the instrument can realize remote control measuring.
9.With the discharging alarm by sound and the discharging indicating clearly function, the mis-operation can be reduced.
10.With AC380V misconnection protection function,perfect back EMF protection function and anti-arcing function.
11.It has the features of dustproof, shockproof, moisture-proof, high precision, good repeatability and portability.
