Overview
HHDC-10A Handheld Grounding Continuity Tester (Handheld Down Conductor Meter) is used for measuring the resistance value of the grounding wire of power equipment in substations. It can effectively detect the increase in resistance value of the lead wire between electrical equipment and the grounding grid due to various reasons, in order to avoid equipment grounding operation.
Functional characteristics
◆ 7”color touch screen, clear interface.
◆ The instrument comes with power down storage, which can store 1000 sets of test data and can be viewed at any time.
◆ The instrument comes with a lithium battery, which is convenient for outdoor use.
◆ Controlled by a high-speed microcontroller, with a high degree of automation and easy operation.
◆ New power supply technology, with multiple current ranges and a wide measurement range.
◆ Digital management of power supply batteries, with functions such as remaining battery display, remaining battery alarm, and overcurrent protection.
◆ Equipped with non power-off data storage and a perpetual calendar, capable of storing 1000 sets of test data and storing test time in real-time.
◆ Equipped with USB flash drive interface and printer expansion interface, optional external micro printer can print test data in real-time.
