Select INT as explained above, and enter the desired frequency using the ten-key.
<Relationship between Measurement Speed and SYNC Mode>
The measurement time (sampling time) is determined by the selected SYNC mode.
The measurement speed (the number of measurements and outputs per second) is determined by the SYNC mode
and the following conditions.
•
Intensity of the display to be measured
•
Measurement mode
•
Data output (RS-232C or USB)
•
Baud rate when data is output via RS-232C
•
Number of measuring probes to be used (when the optional 4-point expansion board is used)
The table below shows the measurement speed for each SYNC mode when measurement is performed under the
following conditions.
RS232C
•
Intensity of the display to be measured ... No errors and warnings, and the luminance is stable.
•
Display mode ........................................... xyLv
•
Baud rate for data output ......................... 38,400 bps
•
Number of connected measuring probes .... 1

Press the
key to confirm the selection.
* To use EXT mode, the vertical synchronizing signal used for the display must be input to the instrument. (Page 28)
* By default (factory setting), the instrument is set so that EXT mode will be selected automatically when the POWER switch is set to ON.
If you want to change this setting, refer to page 29.
