    Frequently Asked Questions
    Q
    What detection methods does the partial discharge sensor support?
    The sensor adopts a modular design supporting multiple detection methods, including general ultrasound, long-distance ultrasound, transient ground voltage (TEV), and infrared temperature measurement — enabling comprehensive partial discharge detection in a single device.
    Q
    What is the resolution and temperature accuracy of the infrared camera module?
    The infrared camera features a resolution of 384×288 with a pixel pitch of 17µm and a focal length of 13mm. The temperature measurement error is ±2°C or ±2% of full scale, making it suitable for precise thermal inspection of electrical equipment.
    Q
    How long does the battery last, and how is low battery handled?
    The device is powered by a rechargeable lithium battery with an approximate working time of 8 hours. The LCD backlight turns off after 5 minutes of inactivity to conserve power. When the battery drops below 5%, the system emits a warning beep — users should save data and shut down promptly for charging.
    Q
    What types of spectrum displays does the system support?
    The system supports a variety of spectrum display modes including gradient color maps, curve maps, characteristic maps, and phase maps. It also has built-in parameters for common electrical equipment types and fault categories, streamlining the diagnosis process.
    Q
    Can the system generate equipment maps and maintenance records?
    Yes. By collecting location data through the analysis host, the system can automatically generate operation and maintenance maps, form a structured equipment ledger, and provide comprehensive oversight of regional operating conditions — greatly improving asset management efficiency.
    Q
