Ep Hipot Electric DC Resistance Tester Transformer Winding Resistance Meter

Product Description

10A 5A Transformer DC Winding Resistance Ohmmeter Tester

10A DC Winding Resistance Tester EPWT-10R

General Information:
DC resistance measurement is a necessary test item for semi-finished product, finished product factory test, installation, handover test and preventive test of power department in the manufacture of inductive coil such as transformer, mutual inductor, reactor and electromagnetic operating mechanism. It can effectively find out the manufacturing defects of inductive coil such as material selection, welding, loose connection parts, missing strand and broken wire, and hidden dangers after operation. In order to meet the needs of rapid measurement of DC resistance of inductive coil, our company has developed EPWT-10R DC resistance tester by using our own technical advantages. The instrument adopts a new power supply technology, with the characteristics of small volume, light weight, large output current, wide range, digital display and so on. The whole machine is controlled by single-chip microcomputer, which can automatically complete self-test, data processing, display and other functions, and has automatic discharge and discharge indication functions. The instrument has the advantages of high precision, simple operation and fast measurement of direct resistance.


Feature:

• Large output current and light weight.
• 6 output current options, and the maximum output current is 10A.
• Can convert the resistance temperature according to the set temperature.
• It has perfect protection circuit and more reliable performance.
• Lithium-ion battery power supply, easy to operate on site.
• It has sound discharge alarm to reduce misoperation.
• 4.3-inch color LCD with 480 resolution × 272 TFT true color display.
• Adopts machine line integration mode, with built-in test line, which is easy to carry.
• Large storage capacity, and can store up to 200 test records.
• With USB interface, test data can be transferred to U disk.
• The parameter setting is more perfect, which can set the transformer test winding, tap position, test phase, test object temperature, converted temperature value, etc.
