Data acquisition with static load
To acquire data at static load levels:
Note Before you start, enter a Sample Points value sufficient to allow data
sampling at the various static levels. A value of 100 should suffice in
most cases.
Note Taking readings near zero should be done only when using bending
strain validation criteria. Avoid using readings near zero if percent level is
used.
1. Start at 0 load. Press the Start button then press the Stop button after several
samples of data have been taken.
2. Manually ramp to (nominally) +50% full scale. Press the Resume button
then press the Stop button after several samples of data have been taken.
3. Manually ramp to +100% full scale. Press the Resume button then press the
Stop button after several samples of data have been taken.
4. Manually ramp to (nominally) +50% full scale. Press the Resume button
then press the Stop button after several samples of data have been taken.
5. Manually ramp to 0 load. Press the Resume button then press the Stop
button after several samples of data have been taken.
6. Manually ramp to (nominally) -50% full scale. Press the Resume button
then press the Stop button after several samples of data have been taken.
7. Manually ramp to -100% full scale. Press the Resume button then press the
Stop button after several samples of data have been taken.
8. Manually ramp to (nominally) -50% full scale. Press the Resume button
then press the Stop button after several samples of data have been taken.
