Switch to Peak Valley Meters
The Running Max/Min meters served well during specimen installation; however, now that you will be
applying a force waveform to the specimen, you need meters that will show you results as they change
over time. Peak/Valley meters provide a better indication of how the system is performing over time.
1. Switch Ch1 Displacement to a Peak/Valley Meter.
In the Station Manager main window, click the Meters button. Click in the title bar of the axial
displacement running max/min meter and change the Meter Type to Peak/Valley.
2. Select a Sensitivity.
Select a Sensitivity that is about 1/10th of the displayed reading.
3. Fine-tune the Sensitivity.
Proper meter sensitivity adjustment enables you to see fluctuations between cycles. When the Sensitivity
is correct, the meter will show minor fluctuations with meter updates no faster than the frequency.
