Displaying Statistical Analysis
The SURETEST Base Unit accumulates torque measurements in a data list. The list is
created with each AUTO or MANUAL data store entry. Statistical analysis is calculated
on the list, and if SET HIGH and SET LOW limits are established, draws a simple
histogram of the results. These features are very useful in statistical process control
(SPC) management. Statistical analysis can be previewed on the display or sent directly
to a printer/computer port. For additional information on setting up printer or PC ports,
refer to Chapter 3—Set Up and Programming in this manual.
