Preparation of the verification

Procedure:
1. Check the function settings.
In the HMI tree they are found under:
Main menu/Settings/IED Settings/Control/SMBRREC(79,0->1)/
1:SMBRREC
If any timer settings are reduced to speed-up or facilitate the testing, they
shall be set to normal after testing. A temporary label on the unit can be a
reminder to restore normal settings after which a verification test should be
performed.
2. Decide if a synchronization check (SYNC) shall be included in the test.
