2.Voice Prompt Function: The instrument is equipped with a human voice prompt function, which can clearly broadcast operation steps and measurement results in real time. This feature helps operators standardize operations, avoid misoperations caused by unclear operation guidelines, and improve the efficiency of on-site work.

3.Comprehensive Visual Display: A 320×240 color screen is adopted to simultaneously display phase difference, frequency, phase diagram, and in-phase/out-of-phase results. The intuitive display interface enables technical personnel to quickly obtain key measurement data, judge the phase relationship between two lines, and make accurate decisions in a short time.

4.Automatic Shutdown Function: The instrument will automatically shut down if there is no operation for one hour, which effectively saves battery power, extends the service life of the battery, and avoids energy waste caused by forgetting to shut down after operation.

5.Detachable and Replaceable Rechargeable Battery: Both the host and the launcher are equipped with built-in rechargeable lithium batteries, which can be disassembled and replaced. This design solves the problem of inconvenient charging in the field, ensures continuous operation of the instrument, and improves the adaptability of on-site work.
