Check Vibration Alarms
1. Press the SELECT key repeatedly until 'Vel' (velocity in mm/s
RMS) is displayed as the measurement type.

standard will also be displayed on the LCD screen. Three alarm
levels are possible and may be shown:

3. Press the SELECT key repeatedly to toggle between machine
groups and support classes.
NOTE: A quick reference list of available values is printed on the
