General Information
GDDT-20U is a highly automatic and portable test equipment. It is applied to the measurement of break-over 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 an ideal dedicated instrument due to small volume, convenient to carry, easy to operate, high-accuracy, fast testing speed, good testing repeat-ability, clear to read.
Features
- The instrument is controlled by high-speed single chip, thus it’s highly automatic and easy to operate.
- Using new power source technology, thus with many current gears and wide measuring range.
- Intelligent power management technology, thus the instrument can work in the state of Min. power, which can reduce internal heating effectively and save energy.
- 65K color LCD with 320X240 dot matrix.
- 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 you can look up at any time.
- Equipped with RS232 and USB interface, it can communicate with computer and use U disk to save.
