Hi,

In your area it is +10 deg 0 sec, ie East of true North.

This means that when you turn around and face South, magnetic South will be 10 deg West of true South, and therefore the SCP, or to the right as you see it. You would therefore place the compass pointer on 170 deg, and note the position of true South on the scale at 180.
