6.
The horizontal axis indicates the orders of the
harmonics.
Display of the levels of the harmonics as a
percentage with respect to the fundamental
(order 1).
Order 0: DC component.
Order (1 to 25): order of the harmonics. As soon
as the cursor goes past order 25, the range from
26 to 50 appears.
Note: the
icon to the right of harmonic 25
indicates the presence of harmonics of order
higher than 25.
7. Use
to select a tool.
: sub-menu selection tool.
: bar chart cursor management tool. Use the
keys to move the cursor from harmonic to
harmonic. The measurement zone (item 3) is
refreshed. A long press on the
or
key
causes a shift to rapid motion.
: 'zoom out' tool. Each press on increases
the vertical scale.
: 'zoom in' tool. Each press on decreases
the vertical scale.
7.3 Current
This sub-menu displays the harmonics of the
current. The information displayed is read as
follows.

Item Function
1. Reminder of the mode used.
2. Instantaneous frequency.
3.
This information concerns the harmonic located
under the cursor (see item 7).
Ah xx: number of the harmonic.
%: level of the harmonic with respect to the
fundamental (order 1).
A: RMS current of the harmonic in question
+000: phase shift with respect to the
fundamental (order 1).
Max – Min: indicators of the maximum and
minimum of the level of the harmonic in question
(reset at each change of harmonic number).
THD: total harmonic distortion (also called THD-
F).
4. Current date and time.
5. Battery charge level.
6.
The horizontal axis indicates the orders of the
harmonics.
Display of the levels of the harmonics as a
percentage with respect to the fundamental
(order 1).
Order 0: DC component (with PAC clip only).
Order (1 to 25): order of the harmonics. As soon
as the cursor goes past order 25, the range from
26 to 50 appears.
Note: the
icon to the right of harmonic 25
indicates the presence of harmonics of order
higher than 25.
