hysteresis also has to be adapted so that
the reset point lies at 50.05 Hz again.

8.4 Display mode (last decimal point off)
In the display mode, the UFR1001E is in its normal state; here, depending on the program, the actual
voltage, the highest actual 10 minute mean value, the frequency or the vector surge is displayed. In
addition, the alarm signals (e.g.
8
8
,
8
8
) and error codes (e.g.
8
8
) are displayed.
