Change Subject:
This button allows the user to perform multiple tests in the same storage file. The test
data for each new subject is kept in a separate table inside the same storage file. The subject entry is used
to identify each data table. This feature is useful for running multiple subjects on the same test.
11.
Save Data:
This button stores the time and count data on the screen into the file designated by the user.
The user must designate a file and subject before data can be stored.
12.
Auto Store Data:
This selection will automatically store the present time and count data anytime the
following buttons are pressed: Stop1, Stop2, Stop3, Stop4, Reset, and Update data. To activate this function,
click the check box under the “Save Data” button. When the box is checked, the auto store function is in
effect. Upon checking the box, the software will prompt the user to designate a storage file and subject
name.
Notes
•
If the timer is set to Multiple timer mode, all four stops will record on split time 1.
•
If the computer is used to start and stop events, there will be a slight delay ( a few milliseconds) between
the pressing of the button, and the execution of the event on the LCD screen of the 54035A. This delay may
or may not be noticeable to the user. It is due to the serial communication timing and can not be improved.
For the most accurate timing results, start and stop the timer from the front or back panel on the 54035A
and use the computer to upload the time data.
Results File Format
All time and count data is stored in an ASCII format. Any program capable of reading this format can be used
to view the data (Excel, Notepad, Word etc.). Please note that if the 54035A software has opened a file, it may
not be possible to view the file until the 54035A software is exited. Each set of data in the file has a header that
includes the subject name and the time and date the file was created. Each time a “Save data” command or auto
store command is given, a line is entered in the results table showing the time and count data present on the
54035A at the time of the command. An event column shows which command in the software triggered each
line of data to be stored. A separate table is given for each different subject inside the storage file.
Applications
Directions in this section (next seven pages) detail setup procedures for interfacing the Multifunction Timer/
Counter to specific Lafayette Instrument equipment. If the equipment being used does not appear on this list,
contact Lafayette Instrument for application instructions.
Setting the Timer to Multiple time mode
Many applications in this section require the timer to be set up in “multiple” timer mode. To do this setup,
simply press the mode button and select “2-multiple” by pressing “2”. Make sure that the timer is stopped and
reset before attempting to enter the mode menu. The mode menu will then prompt to set the switch types.
Unless the application calls for normally closed switches, exit this portion of the menu by pressing “3” for “end”.
