Overview
HDC-10A grounding down lead continuity tester is used to measure the resistance value of the grounding wire of power equipment in substations. It can effectively detect the increase in resistance value caused by various reasons between the electrical equipment and the grounding grid, in order to avoid equipment grounding operation.
Advantage
♦ The instrument is controlled by a high-speed microcontroller, with a high degree of automation and easy operation.
♦ The instrument adopts a new power supply technology, with multiple current ranges and a wide measurement range.
♦ Intelligent power management technology ensures that the instrument always operates at the minimum power state, effectively reducing internal heating and saving energy.
♦ 7” high-definition touch screen, it can freely switch between Chinese and English.
♦ The instrument comes with power down storage and can store 1000 sets of test data, which can be viewed at any time.
♦ Download a dedicated app for mobile phones, control instruments through dedicated software, upload test data, and facilitate access.
♦ The instrument comes with a lithium battery, built-in charger, integrated design, and convenient operation.
