Second, press [soft key 1] and then press the number key [1] in numeric keyboard. Then press [ENTER] to confirm.
Third, press [soft key 2] and then number key [3]. Now the measure result is the first and third harmonic of the
input signal.
Choose [DISPLAY] submenu and choose <Full> in <Display & Scale> option and <List> in <Type> option. Then,
you can read the measured harmonic (harmonic 1 is corresponding to <Xh1>, <Yh1>, <Rh1> and <
θ
h1>;
harmonic 2 is corresponding to <Xh2>, <Yh2>, <Rh2> and <
θ
h2>). The result is shown in Fig.94.
