Heartbeat Verification

The "Heartbeat Verification" module includes the Heartbeat Verification wizard, which
performs a verification of the current device condition and generates the Heartbeat
Technology verification report:
• The wizard can be used via the SmartBlue app.
• The wizard guides the user through the entire process of generating the verification
report.
• The operating hours counter and minimum/maximum temperature indicator (peakhold)
are displayed.
• If the vibration frequency of the fork increases, a corrosion warning appears.
• The order configuration of the oscillation frequency in air is indicated in the verification
report. An increased oscillation frequency indicates the presence of corrosion. A reduced
oscillation frequency indicates that there is buildup present or that the sensor is covered
by the medium. Deviations in the oscillation frequency compared to the oscillation
frequency on delivery may occur due to the process temperature and process pressure.
