Product Description

GDDT-20U Grounding Down-lead Test Earth Continuity Tester



General information

GDDT-20U Earth Continuity Resistance Tester is a highly automatic and portable test equipment. It is applied to the measurement of breakover resistance value among earth connecting cables of substation electrical equipment. The adoption of high-performance single-chip control helps to achieve intelligence of testing process. It is small size, convenient to carry, easy to operate, high-accuracy, fast testing speed, good testing repeatability, clear to read.

Features

1. The instrument is controlled by high-speed singlechip, thus it's highly automatic and easy to operate. 

2. Using new power source technology, with many more current gears and wide measuring range.

3. Intelligent power management technology, the instrument can work in the state of Min. power, which can reduce internal heating effectively and save energy.

4. 65K color LCD with 320X240 dot matrix 

5. Equipped with perpetual calendar and clock (BYO) and with function of saving under the condition of power failure: 1000 sets of testing data can be saved and data can be reviewed at any time.

6. Equipped with RS232 and USB interface, it can communicate with computer and use U disk to save.
