    Description

    The Fast Photo-Electric Brightness Test Meter comprises three primary subsystems: electrical parameter measurement circuitry, photometric parameter measurement circuitry, and a CPU system circuit. Voltage and current signals undergo amplification before transmission to a high-speed A/D converter, with subsequent digital signal routing to the microprocessor. Concurrently, the input current signal from the brightness detector is processed through I/V conversion to the A/D converter, then digitally transmitted to the microprocessor. The microprocessor executes real-time processing of photometric and electrical parameter data, enabling automatic range switching with simultaneous calculation and display functions.

    Key Features:

    • Quad-window display for simultaneous electrical and photometric parameter monitoring, minimizing reading errors
    • Integrated lamp holders for direct lamp installation and testing
    • True RMS measurement of electrical parameters
    • High-accuracy V(λ) correction in photodetector, compliant with national CLASS 1 brightness meter specifications
    • Automatic measurement range switching based on test results
    • Dual watchdog circuit implementation ensuring high reliability and system stability in complex operational environments
