Secure the display�
2
Secure the probe in a way to place its end 30 mm *
away from the display surface�
Be sure to set it perpendicular to the display.
*1: L = 10 mm for mini probes.
L = 28 mm for the CA-VP402.
L = 200 mm for the CA-VP410T.
*2: No hood is used for the CA-VP410T.
Notes on setting
• When measuring displays with high view angle dependence, you can obtain a higher
measurement reproducibility by not changing the setting angle θ for every
measurement. In particular, the CA-VP410 high-sensitivity probe and the CA-VP402 and
CA-VP404 small spot probes have a large aperture angle, which has a greater effect on
the viewing angle. When measuring displays with a high view angle dependence, run
user calibration and use the probe without rotating it from the calibrated position.
• Use of the hood supplied as a standard accessory not only blocks ambient light but
also makes it easier to achieve a proper measurement distance and an angle of 90°.
• The guaranteed-accuracy measurement distance for a Ø27 probe is L = 30 mm ±10 mm.
• The guaranteed-accuracy measurement distance for a Ø10 probe is L = 30 mm ±5 mm.
• The guaranteed-accuracy measurement distance for a mini probe is L = 10 mm ±5 mm.
• The guaranteed-accuracy measurement distance for the CA-VP402 is L = 28 mm ±2 mm.
• The guaranteed-accuracy measurement distance for the CA-VP404 is L = 30 mm ±2 mm.
• The guaranteed-accuracy measurement distance for the CA-VP410T is L = 200 mm ±2 mm.
• When strict low-luminance measurement is required, perform measurement in a dark
room with no external light. Even when measuring in a dark room, the ambient light
from the display itself may act as an external light. In such situations, light shielding
using a hood is recommended. If strict limitations are required, compare measurement
results from a general luminance meter such as the CS-2000, and verify whether using a
hood has any effect.
[Relationship between specification table measurement area and guaranteed-accuracy
measurement distance]
The "measurement area" indicated in the specification table is a value that satisfies the design value at the nominal
guaranteed-accuracy measurement distance.
