Parameter 305 Decimal Point should be configured to "1 digit after decimal point" in case
Encoder interface module is selected in MAG 8000, MAG 8000 CT and MAG 8000 Irrigation;
otherwise proper reading from the device cannot be performed.
10.7 Meter uncertainty
To ensure continuous accurate measurement, water meters must be calibrated. The calibration
is conducted at Siemens flow facilities with traceable instruments referring directly to the
physical unit of measurement according to the International System of Units (SI).
Therefore, the calibration certificate ensures recognition of the test results worldwide, including
the US (NIST traceability).
