Selecting Measurement Time
Select measurement time depending on purpose.
7 modes are available for measurement time.
Select the mode with long measurement time when repeated accuracy is required such
as when measuring object of low luminance.
∗ Setting at the shipment from factory : AUTO.
Zero Calibration
Measurement Time calculated by formula
(Time for integration x 2 +Time to open/close
shutter + Time for calculation) indicating time
needed for actual measurement.
Time for integration
Time for sensor to measure light
indicating “exposure time”.
Super-FAST Not be done every time ∗1 0.5s approx. 300 ms
FAST
Done every time
automatically
1s approx. 300 ms
SLOW 3s approx. 1300 ms
Super-SLOW 12s approx. 1300 ms x 4 times
LTD.AUTO 2 1s or 3s approx. 300 ms or 1300 ms
AUTO 3 1s to 60 s
MANUAL 1s to 60 s (Every 1s)
∗ Zero calibration is performed automatically one minute after previous measurement.
∗ 2 Selects FAST/SLOW automatically depending on luminance. Luminance for which FAST/SLOW is switch-
able is as follows for measuring angle 1˚.
FAST → SLOW: L
v
=20 cd/m 2 or lower (Measurement is redone in SLOW mode.)
SLOW → FAST: L
v
=40 cd/m 2 pt or higher
∗ 3 Selects the measurement time automatically depending on luminance.
For measuring angle 1°, when luminance is higher than 20 cd/m 2 , the measurement time switches as LTD.
AUTO mode. When luminance is 20 cd/m 2 or lower, the measurement time is calculated depend on luminance
as following examples. The higher limit is 60 s.

V
20.0 cd/m 2 15.0 cd/m 2 10.0 cd/m 2 6.6 cd/m 2 4.6 cd/m 2
Measurement Time 3 s approx. 7 s approx. 14 s approx. 30 s approx. 60 s approx.
Operation Procedure
1.
