• 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 mode.



  • Wireless Sampling with Long Distance and Easy Operation

    ·Wireless mode: Suitable for outdoor sites or situations 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 test sites.



    ·Wired mode: Suitable for indoor sites or situations 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 Functionality and Strong Performance

    ·This instrument has multiple test functions such as arrester resistive current testing, monitor current calibration, and monitor operation testing, with strong 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 each step very clear. 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.
