Surface Plate Calibration (Program 1)
(Used with Angular Optics)

Introduction

This program accepts data from the 5526A Angular Optics and computes
the flatness contours of a surface plate. Once the calculations have
been-made, the results can be listed on the calculator printer
and/or stored on the data cartridge for future use by Programs II
and III. These programs provide graphics display of results stored
on the tape. Data can be entered directly from the Laser Display
or via the calculator keyboard in either English or Metric units.
The inspection lines can be entered in any order and any line can
be edited or replaced during the calibration.
Application Note 156-2 describes the complete surface
plate calibration procedure and should be referred to
before making the measurement.
CAUTION: Care should be taken when inputting the data
for the inspection lines or when editing a previously
input line of data. When editing, the new number of
points must equal the number of points in the original
data line. Otherwise, lines of data may overlap and yield
erroneous results.

Operation

1. English (0) or Metric (1) units?
Answer this question according to the switch setting on the Laser
Display or in whatever units the data is to be entered. For example,
if data is English units (inches), respond with "0". (Default =
English).
2. CREATE (0) or EDIT File #) data?
If a new surface plate is to be measured in entirety, answer "0".
If a previously stored data file is to be modified or edited, respond
with the file # that is to be modified. (Default = CREATE).
