    Latency Test Instructions

    • • Press and release keys to measure response time
    • • Shorter latency = better performance
    • • Scan rate is calculated from shortest key press time
    • • Gaming keyboards typically have <5ms latency
    • • Regular keyboards average 10-15ms latency

    Comprehensive Usage Guide

    1

    Ensure keyboard is properly connected and recognized by system

    2

    Press each key sequentially to check key response and feedback

    3

    Test modifier key combinations like Ctrl, Alt, Shift
