testing can be completed with a light touch.
6. Equipped with a calendar chip and a large-capacity memory inside, the results can be
saved at any time. The history record can be viewed at any time, and can be printed out.
The current time and storage time can be displayed and printed.
7. Scientific and advanced data management: The instrument data can be exported
through U disk, and the data can be viewed and managed on any PC through special
software. Ability to generate reports and test reports
8. Safe and reliable. The instrument has functions such as grounding protection, current
limiting and voltage limiting protection, sound and light alarm to ensure the safety of test
personnel and equipment.
9. With vector test function, it can measure ground network impedance and ground
network pure resistance. The impedance angle can be measured.
10. Wiring labor is small, no need for large current wires.
11. All-in-one model, with standard resistance and constant current source, convenient
for on-site testing and reducing on-site wiring.
12. The instrument is easy to operate, and the measurement process is controlled by the
microprocessor. As long as the appropriate measurement method is selected, the data
measurement can be automatically completed under the control of the microprocessor.
13. When the user needs a large current test (such as 30A), this instrument can be
realized by an external power supply.
