Hello rob, from the wording in the picture, that is what it appears to be, I might need to be corrected.
To check the actuall secondary connections for the center tap then I would just do resistance checks on each secondary winding to establish which connections are the actuall center taps if they are not marked as such, they usually follow a logical layout on the transformers connector strip, so it's basically identifying the two seperate windings by doing resistance checks, when you find the highest reading between two connections of either of the secondaries then you have found the two maximum secondary voltage connections ie 60v-60v that should equate to 120v output, next establish the center tap for that winding by a resistance check from either of the 60v connections you have just established, the cener tap connection that you will be looking for for that winding will return a resistance reading that is approx. half the resistance of the resistance reading obtained initially across the two connections you first established.
Once that is established then repeat for the other winding. the readings should return ohms not K ohm or M ohm.
I do not know what experience you may have in these matters so if this is all familiar to you please ignore.

Addition: Al beat me to it, my post should guide you more or less to the same conclusion but using resistance checks as opposed to voltage checks.
