5. Measure the operate time of the timer by injecting 1.2 · VNRelPU and a current to
get two times the set SN_PU operate value.

6. Compare the result with the expected value.
The expected value depends on whether definite or inverse time was selected.
7. Continue to test another function or complete the test by setting the test mode to

1. Set the polarizing voltage to 1.2 · VNRelPU and the phase angle between voltage
and current to the set characteristic angle (RCADir), the current lagging the voltage.
2. Measure that the operate power is equal to the INRelPU setting for the set
directional element.
Note that for pickup, both the injected current and voltage must be
greater than the set values INRelPU and VNRelPU respectively.
The function activates the BFI_3P and STDIRIN output.
Measure with angles j around RCADir +/- ROADir.
