• Consistent wired and wireless measurement data

    ·The data measured by this instrument in wired mode and wireless mode are completely consistent, and users do not need to worry about measurement errors caused by using wireless mode.



  • Wireless sampling, long distance, convenient operation

    ·Wireless mode: suitable for outdoor sites or sites where the PT sampling wiring cabinet is far from the tested arrester. The wireless transmission distance reaches more than 1000 meters, fully meeting the needs of various experimental sites.



    ·Wired mode: suitable for indoor sites or sites where the PT sampling wiring cabinet is close to the tested arrester.



  • Simultaneous three-phase measurement with automatic correction

    ·The instrument has three-channel resistive current simultaneous measurement and provides two anti-interference modes: ①No interference: In this mode, the instrument does not automatically correct the interphase interference angle during measurement; ②With interference: In this mode, the instrument automatically calculates and corrects the interphase interference angle during measurement, and only one wiring connection is needed to complete the measurement of phases A, B, and C simultaneously.



  • Full-featured and powerful performance

    ·This instrument has multiple test functions such as arrester resistive current test, monitor current calibration, and monitor action test, with powerful performance and high test accuracy.



  • Full touch 8-inch color LCD display

    ·Easy to operate. The instrument is equipped with a high-end full touch 8-inch color LCD display. The large display interface shows all operation steps in Chinese menus, making every step very clear. Operators can use it without additional professional training. It is currently a very ideal intelligent measurement device.



  • Large capacity lithium battery, simple and portable

    ·The instrument has a built-in large capacity lithium battery, which can work continuously for dozens of hours on a single charge, completely eliminating the trouble of finding a 220V power supply at the work site.
