5.4.6.2. Harmonics: sub-levels description
Press F1 key (alternatively touch CLP/EXP at display) to expand or compress the
harmonics sub-levels. The parameters inside sub-levels are strictly depending on type of
selected system (see § 5.3.1). Below there are some pictures of different possible
situations:

Inside Harmonics level there is another sub-level where an accurate selection of harmonic
parameters is possible. Move the cursor on “Odd” or “Even” using arrows key and press
F1 key (or touch CLP/EXP at display). The result, referred to Odd harmonics is below

Press F3 key (alternatively touch SEL at display) to select/unselect the desired
parameters. The number of selected and recording autonomy are automatically updated
from meter. The below harmonic parameters can be selected for recording (see § 10.2):
