IVL Test Software Settings

Supports three output modes: voltage, current, and current density;

Supports three output modes: standard, multi-segment, and custom;

Supports setting an initial measurement threshold—below the set value, luminance is not measured; once the set value is reached, luminance measurement begins, saving test time.

 Supports setting spectra under specific voltage and current measurements. Supported instrument parameters can be saved and recalled for the next measurement.

Test Report:

Test result parameters include: luminance, voltage, current, current density, current efficiency, luminous efficiency, external quantum efficiency, color temperature, color rendering index, emission spectrum, half-width, and more.
