Important Measurement Techniques
The variety of items that the instrument can measure is almost
endless. However, to obtain accurate and repeatable
measurements, the bottom of the shoe must be on the surface
to be measured. The reason for this is that any movement
during a reading can cause the data to vary. To obtain the most
accurate and repeatable measurements, there are a few
guidelines you must follow:
•
The sample to read must be larger than the target window
opening.
•
If the sample to be read is smaller than the shoe, you may
want to make a platform—the same height of the
sample—for the instrument to sit on.
•
The sample color should be uniform and consistent across
the measurement area, with no fading or blemishes.
•
The sample should be solid—not clear or translucent.
Taking a Measurement
NOTE: The procedure below provides the basic steps required to
measure a sample. Refer to the Operator’s Manual PDF file located on
the CD supplied with your instrument for more detailed information on all
the functions.
When taking a measurement, be sure to use the previously
discussed proper measurement techniques.
To take a measurement:
1.
Select appropriate location and sample names.
2.
Position the instrument’s target window on the sample
and take a measurement by lowering the instrument to the
shoe and holding. Release the instrument when
