5. Measure the operate time of the timer by injecting a current two times the set
INcosPhi> value and the polarizing voltage 1.2 · UNRel>.

6. Compare the result with the expected value.
The expected value depends on whether definite or inverse time was selected.
7. Set the polarizing voltage to zero and increase until the boolean output signal
UNREL is activated, which is visible in the Application configuration tool in
PCM600 when the IED is in online mode. Compare the voltage with the set
value UNRel>.
8. Continue to test another function or complete the test by setting the test mode
to off.
