1. Selecting the Measurement Speed
Select the measurement speed according to your application.
If the measurement speed is changed, display frequency of the measurement results will change accordingly.
The measurement results are displayed at the following frequency.
FAST mode
Requires short measurement time, but measurement accuracy is not sufficient in the case of measurement of a low-
luminance display.
SLOW mode
Repeats measurement in FAST mode five times, and displays the average of the five measured values. This mode
is used when you want to perform accurate measurement.
AUTO mode
Switches measurement speed to FAST or SLOW automatically according to the luminance of the display mea-
sures.
The measurement speed switches from FAST to SLOW or vice versa at the following luminance.
FAST → SLOW: When Lv drops below 1.0 cd/m
2
.
SLOW → FAST: When Lv exceeds 2.0 cd/m
