Tankvision configuration

A modified checksum indicates that changes have been made to the system. The checksum must
be documented (e.g. by printing out the screenshot, see Figure "Tankvision W&M Seal") and
recorded in the acceptance report (e.g. by attaching the printout).
!
Note!
The checksum can be recalculated by switching the Field Scan off and then on again.
Checking the W&M display
The following steps must be taken to check the weights and measures display:
• The settings listed under Section to "Sealing tank data" can no longer be modified.
• A "WM" in front of the values for the "Product Level", "Product Temperature" and "Total
Observed Volume" indicates that the values are calibrated.
• The level and temperature information has to match that of the field devices.
Checking the printouts
All printouts from connected printers that cannot be officially verified must bear the annotation
"Measured values not calibrated" and no measured values may appear as calibrated.
