How to use Analogue output connector
The variation in brightness such as building-up time, falling-down time, and frequency can be
measure by connecting the oscilloscope.
Select one filter from X

, Y, Z Tristimulus values filter or No Filter. And pull out analogue signal
from the photo detector via analogue output connector.
■Relation between Analogue voltage and Luminance
The output voltage range in each measurement range is from 0.05V to 3V (default).
Readout data of Luminance have relation with analogue output voltage as following table.

Notice
・
The correlation function between the Analogue output voltage and the
luminance value vary from instrument to instrument. When you determine
luminance value from the analog output voltage, check the correlation
function beforehand.
・
When you select [USER] in sensitivity setting, above list is not adopted.
