Sealing
Sealing after initial startup
After installation and/or fault diagnosis, devices that are subject to obligatory calibration must be protected by the user to prevent possi-
ble unauthorised tampering.
Important!
Consumption readings from unsealed devices may be disputed by the user on receiving the corresponding bill.
For this reason, the device is protected with wired lead seals at the following points:
Measuring transducer
Seals on each of the two fixing screws of
the measuring transducer
Factory seals
The measuring transducer is supplied with seals ready-attached at the following points:
Measuring transducer; calibration seal under the frame
Important!
The factory-applied seals must not be damaged or tampered with. Consumers may, when they receive the corresponding
bill, dispute the readings from devices with damaged factory seals.
