6.5 Function Test
6.5.1 Measuring Element
Measuring element characteristics are realised by software, so it is possible to verify the overall
characteristics by checking representative points.
Operation of the element under test is observed by assigning the signal number to a configurable
LED or a binary output relay.
CAUTION
After testing, the original settings must be restored.
In the case of a three-phase element, it is sufficient to test for a representative phase. The A-phase
element is selected hereafter.
