If a measured value is not available (for example, thermal values, if the device does
not have thermal protection, or if the 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 cur-
rent is flowing), then "—" appears (a long dash). If the measured value overruns, then

"
" (3 asterisks) are displayed.
Double click on the desired measure value group; e.g. 3ULPDU\ 9DOXHV. The next
subgroup is displayed. See Figure 7-24.
Double click on the desired sub-group; e.g. 2SHUDWLRQDO YDOXHV SULPDU\.
By double clicking on an entry in the list on the right side of the window, the associated
contents of the measured value group are displayed in another window, as shown in
Figure 7-25.
Measured values, as a percentage of the nominal quanti-
ties.
The nominal quantities are determined by the version of the
device and possibly the nominal value settings (addresses
 9 35,0$5< 23,  , 35,0$5< 23, refer sub-
section 6.1.3).
Minimum, maximum, and average values, in primary quan-
tities.
These are further subdivided into:
Averages over a defined time period;
Minimum and maximum values for voltages and currents,
with the date and time of the occurrences;
Minimum and maximum values for real, reactive, and appar-
ent power; frequency; and power factor; with the date and
time of the occurrences;
Minimum and maximum values for the averages, with the
date and time of the occurrences;
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 quantities.
See Sub-section 7.1.2.
Other measured or calculated values. These are further
subdivided into:
Thermal measured values from protective functions that cal-
culate them, such as overload protection, if such functions
are present; the percentages are relative to the tripping tem-
perature rise or the maximum allowable temperature rise;
User-defined measured values, which are measured values
that are defined by the user during initial setting of the de-
vice (see Section 5.2).
See Sub-section 7.1.3.2.
See Sub-section 7.1.3.3.
