Heartbeat Verification

The "Heartbeat Verification" module contains Heartbeat Verification wizard, which
verifies the current instrument health and creates the Heartbeat Technology verification
report:
• The wizard can be used via the SmartBlue app.
• The wizard guides the user through the entire process for creating the verification
report.
• The operating hours counter and minimum/maximum temperature indicator (peakhold)
are displayed.
• If the oscillation frequency of the fork increases, a corrosion warning appears.
• The as-delivered state of the oscillation frequency in air is indicated on the verification
report. A high oscillation frequency is an indicator of corrosion. A lower oscillation
frequency indicates buildup or a sensor covered by the medium. Deviations of the
oscillation frequency from the oscillation frequency in the as-delivered state can be
caused by the process temperature and process pressure.

Proof testing for SIL/WHG devices

The proof test is only available for devices with SIL or WHG approval.
The "SIL Proof test" module, the "WHG Proof test" module or the "SIL/WHG Proof test"
module contains a SIL/WHG Prooftest wizard, which must be performed at appropriate
intervals in the following applications: SIL (IEC61508/IEC61511), WHG (German Water
Resources Act (Gesetz zur Ordnung des Wasserhaushalts)):
• The wizard can be used via the SmartBlue app.
• The wizard guides the user through the entire process for creating the verification
report.
• The verification report can be saved as a PDF file.
