If a measured value is not available (for example, thermal values, if the device does
not have thermal protection, or if this protection is set as "GLVDEOHG"), then instead
of the measured value, 3 dots appear. If the value is undefined (e.g., cos ϕ, when no
current is flowing), then "---" appears (3 horizontal bars). If a measured value over-
runs, then "

Operating measured values, secondary.
The values of the measurement quantities that are present
directly at the terminals of the device are issued.
Ground fault measured values, secondary.
The real portion, I
, and reactive portion, I
Nsw
ground connection current. The values of the measurement
quantities present directly at the device terminals are given.
Operating measured values, in percent of nominal quanti-
ties.
The nominal quantities are determined by the version of the
device and possibly nominal data settings entered (ad-
dresses  9 35,0$5< 23,  , 35,0$5< 23,
refer subsection 6.1.3)
Long-term average, in primary quantities.
The measured values are converted from secondary to pri-
mary according to the settings entered for the current and
voltage transformers, and the nominal device values.
Minimum and maximum of the averages, with the date and
time that they occurred, in primary quantities.
The measured values are converted from secondary to pri-
mary according to the settings entered for the current and
voltage transformers, and the nominal device values.
Minimum and maximum of the voltages and currents, with
the date and time that they occurred, in primary quantities.
The measured values are converted from secondary to pri-
mary according to the settings entered for the current and
voltage transformers, and the nominal device values.
Minimum and maximum of the real, reactive, and apparent
power, the frequency, and the power factor.
The measured values are converted from secondary to pri-
mary according to the settings entered for the current and
voltage transformers, and the nominal device values.
Thermal values from protective functions that calculate
them, such as overload protection, provided such functions
are present.
The percentages given are relative to the tripping tempera-
ture rise for overload protection, and to the maximum allow-
able rotor temperature rise for restart blocking.
Measured values that are defined by the user during initial
setting of the device (see Section 5.2).
