If you are not up measure all three phases at once, you can also touch 'Go...' to choose a
phase to be measured. In the appearing window every Phase A, B and C has its own button.
Touch one of those buttons to start a single phase measurement. In this case no other
phase than the chosen one will be tested.
This Option is also used to do a 'GO Tap' if you have tabs. Please see chapter '8.1.4 Taps'
about how to define a transformer with taps.
