Product Introduction

ETCR3670 Transformer DC Resistance Tester is used to quickly measure the DC resistance of various transformer windings. Semi-fnished products and finished product factory test, installation, handover test and preventive test of the power department in transformer manufacturing are mandatory test items, and the tester can effectively find the material selection, welding, loose connection parts, lack of shares, broken wires and other manufacturing defects and hidden dangers after operation of transformer windings.
ETCR3670 Transformer DC Resistance Tester consist of host, test line, temperature sensor and USB communication line, etc. The instrument adopt with the microprocessor technology and precision 4-wire method to test, accurate and reliable. The instrument with two power supply mode AC 200V and large capacity lithium battery, two measurement mode automatic measurement and manual measurement. The instrument has the function of converting resistance at 75℃ to compensate for the temperature and material of the test product. The instrument adopt with 5 inch full-color high definition touch screen with backlight adjustment function, which is clearly visible under strong light, also equipped with waterproof protective box, which is anti-collision, anti-fall, waterproof, strong, safe and durable. With built-in printer, Bluetooth communication, and USB interface. The instrument has the functions of automatic discharge, alarm, clock and automatic shutdown, etc, which is the ideal tester for quickly measure the DC resistance of the transformer.
1.Two power supply mode AC 200V and large capacity lithium battery, meet the requirement of user on various occasions.
2.Two measurement modes, automatic measurement mode: the test current can be automatically selected according to the load. Manual measurement mode: There are 7 gears to test current
3.Test current gears: AUTO, 10A, 5A, 1A, 100mA, 10mA, 1mA
4.Max. output voltage is 24V, the max. test current is 10A, fast-speed testing, and it can be applied to transformer measurement.
5.With discharge function, which is automatically discharged after the test, and the discharge instructions are clear to avoid misoperation.
6.The function of converting resistance at 75℃ to compensate for the temperature and material of the test product
7.Alarm function, can setting the resistance alarm threshold.
8.Memory: data storage 600 groups
9.5 inch true-color touch screen
10.Built-in printer
11.Bluetooth communication function
12.USB communication interface
