Measurement Synchronization Modes - Konica Minolta CA-410 Instruction Manual

2. Measurement Synchronization Modes

Measurement synchronization modes are designed to select a measurement time (integration time) according to the
vertical scanning frequency of a display. A probe has the following six types of measurement synchronization modes. Select
a mode suitable for the type of the display to be measured.

Mode for measuring while synchronizing
with the display's vertical
EXT synchronization signal input (refer to
page 22 for how to input vertical
synchronization signals)
Mode used when the display's vertical
scanning frequency is unknown or
UNIV
cannot be input; a mode that can
measure any display
When the display's vertical
synchronization signal is known, set that
INT
information so that it can be used for
measurement.
Mode that allows you to specify the
MANUAL
integration time
On a flickering LCD, the screen is fluctuating at half the frequency of the vertical scanning frequency. When you
Memo
measure a display in this state, the luminance and the chromaticity vary if you set the same integration time as the
vertical scanning frequency.
When measuring with the measurement synchronization mode set to MANUAL, set the integration time double (or
another even multiple of) the vertical scanning frequency to ensure stable LCD measurement.
