Destruct Testing Program - Unitek MICROPULL IV MP4/115 Operation And Maintenance Manual

CHAPTER 3: OPERATING INSTRUCTIONS
7 If the "Increment Serial Number" field contains an "N", the request for a new serial number will be
made as illustrated below. The serial number is keyed in; <Enter> is pressed to terminate the entry.
8 If a function key is pressed before any tests are made, the following report will be printed:
9 To exit this program, press <F10>. This will close all open files. enable the MP4 and restore BASIC
Default Legends to the bottom of the screen. Type SYSTEM <Enter>, to return to DOS.

Destruct Testing Program

1 A "Y" in the "Load Histogram History File" field will cause the program to load the data contained in
the file "C: \MP4 \PULLS. TXT". An "N," entered before testing begins, will permit the operator to
overwrite the "PULLS.TXT" file with new data at the end of the test. During testing, the results will be
added to the data contained in the "PULLS.TXT" file.
NOTE: Exiting the program does not erase the contents of the "PULLS.TXT" file. If the file does not exist,
the software will assume that it does, and that it contains zeros.
The PULLS.TXT file consists of 261 entries (cells), each containing the number of pulls that broke
within the limits of that particular cell. Each cell represents 0.5% of the full scale rating of the beam.
For example, on the 100 gf beam, each cell would represent 0 .5 gf or 5 mN. Cell #0 would contain the
number of bonds that broke at less than 0.5 gf. Cell #1 would contain the number of bonds that broke
between 0.5 gf and 0.9 gf, etc. The contents of PULLS.TXT can be examined using any word processor
which can read and write ASCII files.
2 Whenever a histogram is plotted using the <F5> Graph command, the software will save the data to an
ASCII file named, "PULLS.TXT" unless the "Load the Histogram History File" field in the "Define
Hardware" option screen contains an "N".
