the product to ensure proper contact with the sample port and to ensure that it does not pillow
into the sample port. Average several readings when measuring samples that are textured,
patterned, or irregular in color.
Examples of ways to measure several types of samples are given below.
•
Directional Samples
Directionality can be minimized by averaging several measurements with rotation of
the sample between readings. Examination of the standard deviation displayed with
the averaging function can guide in selecting the appropriate number of readings to
average.
•
Non-opaque Samples
Non-opaque samples must have consistent backings. A white uncalibrated tile is
recommended. If the sample is such that it can be folded to give multiple layers,
such as tissue or fabric, the number of layers for each sample should be noted.
•
Translucent Samples
Light trapped in a translucent sample can distort the color. The thickness of the
sample presented should be chosen to maximize color difference between limit
samples and the sample should be backed with multiple layers or a White Tile to
eliminate the effects of ambient (room) light. Translucent liquids can be measured
using in a sample cup, or a sample cup with the ring-and-disk set with the sample
has low solids.
