Functions:
- Photometry:
    • Conversion A/%T/E.
    • The results can be recorded, renamed, deleted, saved, and printed.
- Quantification:
    • Single wavelength, dual wavelength (difference, ratio).
    • Three ways to set a standard curve (entering coefficients, measuring 2 to 10 standard samples, or entering the absorbance values and concentration of standard samples).
    • Three adjustment methods (zero linear, linear, quadratic).
    • Standard curves can be saved and loaded.
    • 19 common concentration units built-in and user-defined units (up to 8 characters).
    • The results can be recorded, renamed, deleted, saved, and printed.
- Spectrum:
    • The scan speed is optional (low, medium, high).
    • The scan interval is optional (0.1, 0.2, 0.5, 1.0, 2.0, 5.0, 10.0nm).
    • The display mode A/%T can be changed.
    • Automatic peak search.
    • Point by point view (peak).
    • Adaptable and modifiable coordinates.
    • The curves and data can be deleted, saved, and printed.
- Files:
    • Files can be deleted, renamed, batch import/export, converted to .txt and .csv format.
- System:
    • System calibration (dark current, wavelength, system baseline).
    • Light source management (light source switch, timing).
    • Clock.
    • Memory management (storage status display, formatting).
    • Six languages can be chosen (Spanish, English, French, Portuguese, German, Simplified Chinese).
    • General settings (tone, brightness, close screen after, sample holder).
    • Reset default values.
    • About (system information).
