7.1.3 Measured and Metered Values
Operating measured values and metered values are determined in the background by
the processor system. They can be viewed from the front of the device, read out via
the operating interface using a PC with DIGSI
®
4, or transferred to a center via the
SCADA interface.
No password entry is required to view the measured or metered values. The values
are updated every few seconds.
Most measured values can be displayed in primary quantities, secondary quantities,
and percentages based on nominal values. A precondition for correct display is that
the nominal values be correctly set in the system data (Addresses  to ).
The secondary values are either the measured or calculated. Table 7-1 gives an over-
view about the formulas to convert secondary values to primary/percentage values.
