When the “Frequency adaptation mode” is set to “Auto” the
frequency will be automatically updated. When the device has
measured voltage for approximately 45 seconds the adapted frequency
field will update even it has been set previously.

In case the adaption mode is set to “manual” you can set the frequency
in adapted frequency field which will not be updated even the measured
frequency is different but relay will internally use the calculated
frequency whenever available.

“Fixed” mode means that frequency will not have any update from
measured voltage and the set value only will be used. This mode is
recommended to be used especially with line differential function.
