6.2.2 Preheating Parameter Settings

See Figure 6-5.

Number	Note
①	Click “Preheating Parameter Settings”
②	Warm-up Duration Setting: The purpose of the warm-up is to allow the light fixture to remain on for a period of time until its luminous and color parameters stabilize, after which the test proceeds automatically.
③	Sampling interval: The software automatically takes samples at the set interval throughout the entire warm-up period to obtain real-time data. We recommend setting the interval to 5 seconds or longer.
④	If this box is checked, the test will begin automatically once the light fixture reaches a stable state, skipping the remaining warm-up time; if this box is not checked, the test will begin only after the warm-up period has elapsed as set.
⑤	If this box is checked, test reports for all sampling points will be saved automatically; if it is unchecked, only the final test report will be saved automatically.
⑥	Definition of a luminaire’s steady state. If the values are set to 20 and 0.5%, the luminaire is considered to be in a steady state if the parameter has not varied by more than 0.5% over the past 20 minutes.
⑦	You can select which parameters the software should use to determine whether a light fixture is stable: optical parameters, electrical parameters
⑧	The software will save the change curves for the selected parameters during the warm-up period in the test report.
