• Consistent wired and wireless measurement data

    ·The data measured by this instrument via wired and wireless methods are completely consistent, so users need not worry about measurement errors caused by using the wireless method.



  • Wireless sampling, long distance, easy operation

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



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



  • Simultaneous three-phase measurement with automatic correction

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



  • Full-featured and powerful performance

    ·This instrument has multiple testing functions such as arrester resistive current testing, monitor current calibration, and monitor operation testing, with powerful performance and high testing 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 and understandable. Operators can use it without additional professional training, making it an ideal intelligent measurement device.



  • Large-capacity lithium battery, simple and portable

    ·The instrument has a built-in large-capacity lithium battery that can work continuously for dozens of hours on a single charge, completely eliminating the need to find a 220V power source at the work site.
