How To Set A Probe; How To Connect Cables - Konica Minolta CA-410 Instruction Manual

7. How to Set a Probe

1
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.
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 has 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 light-shielding cylinder 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°.
• For a Ø27 probe, the specification range of the length is 30 mm±10 mm.
• For a Ø10 probe, the specification range of the length is 30 mm ±5 mm.
• For a mini probe, the specification range of the length is 10 mm ±5 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 light-shielding
cylinder 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 light-shielding cylinder has any effect.

8. How to Connect Cables

A probe has a USB connector for connecting a USB mini B plug and a connector for connecting an RS-232C mini DIN plug.
Before connection, make sure that power is not supplied to the probe and the external device. Be sure to connect a cable
plug to the specified connector.
• For USB connection with a PC, connect the USB mini B plug of the supplied USB cable IF-A28 to the USB connector of the
probe. Connect the USB plug on the other side of the cable to the USB connector of the PC.
