User Maintenance
This chapter describes the operations to perform before starting measurement,
and the procedures necessary to ensure accurate measurements.
Description
Necessity of User Maintenance
Through repeated use, the fixture's measuring performance will gradually
deteriorate over time due to smearing on the contact faces from solder
buildup, and to mechanical wear and deformation of the contact faces
themselves. To continually achieve optimal measurement results, it is
important to keep the contact faces in good condition and take appropriate
action before such wear or deformation occurs. Therefore, the fixture should be
properly cared for by implementing each of the maintenance items shown in
