Lighting support Provides illumination for operation, improving visibility of displays, controls, and the work area. Automatic shutdown Automatically powers down after inactivity to reduce energy consumption and protect the device. Backlight switch support Allows easy on/off control of the backlight, enabling comfortable viewing in varying ambient lighting conditions. Wavelength memory function Stores the last used wavelength setting for quick resume in multi-step tasks and workflows. Use scenarios - Laboratory spectroscopy workflow Set up measurements with reliable illumination and quickly resume work by recalling the last wavelength setting, reducing downtime between steps. - Field calibration and outdoor work Operate in environments with changing light conditions; backlight control and automatic shutdown help maintain visibility while conserving power. - Routine instrument setup and testing Begin a sequence by restoring the prior wavelength setting, streamlining repetitive tests and improving workflow efficiency.
