Selecting, Measurement Speed, SYNC Mode, Display Mode
and the Number of Display Digits
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-
intensity display.
SLOW mode
Repeats measurement several times and displays the average. This mode is used when you want to perform accu-
rate measurement.
AUTO mode
Switches measurement speed to FAST or SLOW automatically according to the luminance of the display measures.
Normally, this measurement speed is recommended.
The measurement speed switches from FAST to SLOW or vice versa at the following luminance .
(LED Universal Measuring ø27 Probe) FAST → SLOW :When Lv drops below 4.0cd/m
2
.
(CA-PU32/35) SLOW→ FAST :When Lv exceeds 6.0cd/m
2
.
(LED Universal Measuring ø10 Probe) FAST → SLOW :When Lv drops below 12.0cd/m
2
.
(CA-PSU32/35) SLOW→ FAST : When Lv exceeds 18.0cd/m
2
.
(LED Flicker Measuring ø27 Probe) FAST → SLOW : When Lv drops below 2.0cd/m
2
.
(CA-P32/35) SLOW→ FAST : When Lv exceeds 3.0cd/m
2
.
(LED Flicker Measuring ø10 Probe) FAST → SLOW : When Lv drops below 6.0cd/m
2
.
(CA-PS32/35) SLOW→ FAST : When Lv exceeds 9.0cd/m

.
(In the case of Flicker Mode**, the measurement speed is always FAST mode.)
