SECTION 2
INSTRUMENT POSITIONING &
MEASUREMENT TECHNIQUES
The variety of items that the 978 can measure is almost endless.
However, in order to obtain accurate and repeatable measurements, the
bottom of the shoe must be:
* Parallel with the surface to be measured if the surface is flat.
* Tangent to the surface to be measured if the surface is curved.
The reason for this is that any movement during measurement can cause
the reading to vary. To obtain the most accurate and repeatable
measurements, there are a few guidelines you can follow.
If the item to be measured is smaller than the shoe, you may want to
make a platform (the same height of the item) for the instrument to sit on.
If the item to measure is curved, you may want to make a jig for the item
to rest in.
Shown below and on the next page are some examples of methods used
to accomplish this. Example 1 shows a platform for measuring a paint
chip. Example 2 shows a jig being used to measure a cup. Example 3
shows a jig being used for measuring a small knob.
☛ A stand is available from X-Rite (P/N 968-80). The stand can hold objects that are a maximum of 4"
inches in width, or 2" inches to the center of the object. Refer to Appendix C for further information
about this mounting fixture.
