GDDT-10U Digital Grounding Down Lead Earth Continuity Tester
GDDT-10U 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.
● The instrument is controlled by high-speed single chip, thus it's highly automatic and easy to operate.
● Using new power source technology, with many more current steps and wide measuring range.
● Intelligent power management technology, the instrument can work in the state of Min. power, which can reduce internal heating effectively and save energy.
● 7 inch LCD touch screen.
● 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.
● Built-in battery
