DC AC Current On-line Measurement Tester GDCR7100D
GDCR7100D is specially designed and manufactured for on-line measurement of DC and AC current below 600V. It adopts CT and digital integration technology. The clamp has no exposed metal conductor and non-contact measurement to ensure safe operation. Ultra-large clamp, easy to clamp to measure thick wire. It is widely used in electric power, communication, meteorology, railway oilfield, construction, metrology, scientific research and teaching units, industrial and mining enterprises and other fields. It is a necessary tool for electrical safety testing.
The instrument has the functions of peak hold, data hold, data storage, etc. It is equipped with USB communication interface, communication cable and monitoring software. It can monitor and query history on-line and display history data dynamically. It has the functions of reading, saving and printing history data.
