Overview

Product Function

Applied to measuring transformer winding resistance; grounding continuity resistance; cable & conductor resistance; contact resistance of switches, connectors and relays; metal riveting resistance; winding resistance of coil, motor and transducer; connection resistance between metal components; welding point resistance; Battery parallel connection resistance; wire length measurement and calculation, etc.

Product features

1. The tester is controlled by a high-speed single-chip microcomputer, with fast response speed, stable measurement and easy operation.

2. With two measurement modes-automatic measurement mode: the test current can be automatically selected according to the load; Manual measurement mode: There are 7 gears test currents can be chose from 20A, 10A, 1A, 100mA, 10mA, 2mA and 1mA.

3. Equip with 480×854 true color LCD touch screen, which is clearly visible under strong light, and can be used for both touch screen and panel buttons. Large capacity rechargeable lithium battery and waterproof case are suitable for outdoor use.

4. With Bluetooth communication function, can do test operations or view the test result on the mobile phone after install the APP.

5. The tester has USB interface and monitoring software, which can communicate with the computer.

6. The protection function is perfect, which can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable.

7. With the function of discharging, which can automatically discharge after the test, and the discharge indication is clear to avoid misoperation.

8. With the function of converting resistance, which can compensate and convert the temperature material of the test product.

9. Alarm function, the resistance alarm value can be set.

10. Automatic shutdown function, the tester will automatic shutdown after 15 minutes without any operation.
