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.

Description of mode
Measurement time

signal input
NTSC Mode for measuring NTSC displays 33.3 ms 59.94 Hz Not required
PAL
Mode for measuring PAL and SECAM
displays
40.0 ms 50 Hz Not required
EXT
Mode for measuring while synchronizing
with the display’s vertical
synchronization signal input (refer to
page 22 for how to input vertical
synchronization signals)
(1 vertical scanning
period)
×2
0.50 to
240.00 Hz
(For FMA:
0.50 to 130.00 Hz)
Required
UNIV
Mode used when the display’s vertical
scanning frequency is unknown or
cannot be input; a mode that can
measure any display
100 ms — Not required
INT
When the display’s vertical
synchronization signal is known, set that
information so that it can be used for
measurement.
(1 vertical scanning
period)
×2
Settable range
0.50 to
240.00 Hz
(For FMA:
0.50 to 130.00 Hz)
Not required
MANUAL
Mode that allows you to specify the
integration time
Settable range
4.0 to 4000.0 ms
(For FMA:
7.7 to 4000.0 ms)
— Not required
Memo
On a flickering LCD, the screen is fluctuating at half the frequency of the vertical scanning frequency. When you
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.
