Running The Program; Archiving The Data; Refining The Test - Mecmesin MultiTest-x Series Operating Instructions Manual

Press the [Stop/BK SP] key twice to return to the Main Menu.

6) Running the Program

i) At the Main Menu screen, press [1] until 'TUTORIAL-1' is displayed
ii) Press [Stop/BK SP], to load 'TUTORIAL-1' and display the 'live screen'
iii) Press [(-)/Tare], [1] to set the load and displacement reading to zero
iv) Press [Start/Ent] to run 'TUTORIAL-1'
v) Pull gently on the loadcell and try to keep the reading as close as you can to
'20 N' for the next ten seconds

7) Archiving the Data

The data associated with this test:
i) The Test Results
ii) The 'Raw' XY Data
iii) The Procedure
iv) Calibration Information
can be archived via the Print menu (see [1], [2]). Copies of typical data files from this
tutorial can be found on the support CD-ROM supplied with each MultiTest-x system.
(Note that, once data have been downloaded to an archive PC or datalogger, there is
no facility for downloading such data to another MultiTest-x system)

8) Refining the Test

Once a test has been developed and run a few times, a number of improvements
which could be made will now, almost certainly, have become apparent. For example,
in this program:
Ignoring all the test data observed in the first one second (i.e. 0.1mm of travel) of the
test might appear to work well, but this only gives accurate results if the operator waits
for exactly one second before starting to pull on the loadcell!
A test which would give equivalent results no matter how long the operator delays
before starting to pull on the loadcell would be much more useful. This test can be
refined by instructing the MultiTest-x not to start recording data until a certain load has
been observed – this can be achieved by using the 'Threshold' facility:
