DB not connected directly to the main supply.
The confusing bit, characteristics at this DB, is this still related to the Distribution circuit.
You can actually read it both ways, I’ve been entering the Distribution circuit but now have my doubts.

Where the supply is from.

You've been doing it right. It's the Zs and PFC of the distribution circuit as measured at far end (the sub-main consumer unit)
This then gives you the base-line if you want to ~~fabricate~~ calculate Zs readings from the R1+R2 readings of the final circuits.

It's self explanatory. You're selecting an existing DB, then a sub DB, then entering the details for the sub DB and then the test results at it.
A distribution circuit is feeding the sub and needs listing as an out going circuit from the main DB.
Hope it helps.
