7.12.2.1 TURN MODE
7 modes can be selected when TH2829X tests TURN.
 TURN_v= primary nominal * secondary voltage/ primary voltage.
This mode is used test transformer turn number.
 TURN = primary nominal * secondary turn/ primary turn. When the
primary inductance is small, using this mode can test the turn number more
accurately. But, when testing magnetic core with high magnetic conductivity,
in such mode, the data will be unstable due to the polarized magnetic core.
