Sample Presentation and
Measurement
Sample Presentation and Measurement Overview
You must pay close attention to the positioning of the sample to insure an accurate
measurement. When positioned correctly, the sample rests between the sample holder
and the front panel door. The sample must completely cover the aperture opening.
Reflectance Measurements
1. Grasp the sample holder and pull forward.
2. Position the sample, then carefully bring arm back up to normal operating
position.
WARNING
Do not allow sample arm to spring back. Also, the sample arm attaches
to the instrument via two captive fasteners that can be hand tightened.
Before first use, ensure that the sample arm is firmly attached.
For the Datacolor 800V (vertical mount), the cylindrical, spring-loaded
sample holder can be depressed to position your sample. You can
return the cylinder to its normal position with a quarter turn of the
cylinder.
Sample Viewing Port
When measuring small samples, you may need to check that the sample is properly
positioned at the port. To verify that the correct area of the sample is being measured:
1. Place the sample at the port. Grasp the black tab above the aperture plate.
2. Pull top of door down to its full horizontal position.
3. The backside of this door reveals the area of the sample covering the port
opening. If necessary, adjust the placement of the sample to target the portion of
the sample to be measured.
4. Push the door back to its normal position.
