Dc resistance measurement is a test item for semi-finished products, finished products factory test, installation, handover test and preventive test of electric power department in transformer manufacturing. It can effectively find the material selection, welding, loose connection parts, missing strand, broken wire and other manufacturing defects and hidden dangers after operation of transformer coil.

In order to meet the needs of transformer DC resistance measurement, the company has developed a tool YCR9910E handheld DC resistance tester with its own technical advantages. This instrument is an innovative product, small size, handheld operation, battery power, easy to carry. It has the characteristics of small size, light weight and large output current. The whole machine is controlled by single chip microcomputer, which can automatically complete self-test, data processing, display and other functions. It also has the functions of automatic discharge and discharge sound alarm instruction. The instrument has high measurement precision and easy operation, and can realize the rapid measurement of transformer DC resistance.

 

1. The instrument output current is large, and the weight is light, light and powerful, easy to carry.

2. The instrument provides 6 output current options, large enough to output 10A current.

3. Built-in large capacity lithium battery, easy to operate on site, can work for more than 8 hours.

4. Wide measuring range (0-50kω), suitable for transformer, transformer, reactor, generator, motor and other inductive test products, can also be used to measure switch, copper bar, contactor, relay contact, metal wire, cable accessories and other test products measurement.

5. This instrument with calendar, 99 groups of data storage, manual temperature conversion and other functions, shutdown without losing data.

6. The menu is simple and friendly, the display data is clear and easy to read, and it can be clearly displayed under the sun.

7. The machine has sound discharge alarm, discharge indication is clear, reduce misoperation.

8. This machine has the characteristics of high precision, shockproof, anti-interference, high stability, easy to carry and so on.

9. With perfect protection circuit, test line accidentally disconnected or power interruption, built-in perfect discharge circuit and back potential protection circuit to make it has a strong ability to resist arc.

10. Graphical interface, intuitive and concise, support Chinese and English switching.
