Option Description
Backlight duration
Time waveform capture
Scroll and select to set the delay time for the display backlight. If no key is pushed during the set time, the backlight turns off to save battery power. The backlight turns on when any key is pushed.
Scroll and select the number of measurements where the time waveform is to be captured. The
Tester captures and stores the time waveform data for the selected number of measurements.
Note
Capture and review of time waveform data is useful in advanced vibration analysis, but keep in mind that data capture uses a significant amount of memory. Captured time waveforms can only be viewed in the Viewer Software, not in the Tester.
Units
Language
Scroll and select a unit of measurement as US or metric. Also select the units for the vibration amplitude. VdB and in/sec for US. VdB* indicates VdB Europe and mm/sec for Metric.
Scroll and select a language.
Overall Vibration Unit
