7. MAINS ANALYSIS
7.1. PWR: REAL TIME MEASUREMENT OF THE MAINS PARAMETERS
This function allows measuring the voltage of the electrical mains and of the relevant
harmonics. Using an external clamp, it is also possible to measure the current and the
relevant harmonics as well as other electrical parameters such as power, power factor, etc.
The following operating modes are available:
 PAR measurement of electrical parameters such as current, voltage, power, power
factor, etc.
 HRM V measurement of voltage harmonics
 HRM I measurement of current harmonics

Press the MENU key, move the cursor to PWR
in the main menu by means of the arrow keys
(,) and confirm with ENTER. The
instrument measures in real time and displays,
in a screen similar to the one reported here to
the side, the instant value of the input
parameters, and RUN appears on the right
bottom part of the display

Use the ,  keys to select the parameter to be modified, and the ,  keys
to modify the parameter value.
It is not necessary to confirm the selection with ENTER.
Func
The virtual Func key allows setting the measuring mode of the
instrument, which may be: PAR, HRM V, HRM I
FS
The virtual FS key, active only when the PAR mode has been
selected with the Func key, allows selecting the clamp full scale
among the values: 1A, 10A, 30A, 100A, 200A, 300A, 400A,
1000A, 2000A, 3000A. The changes made to the FS value will also
be applied to the LEAK function (§ 6.9). If the FS 100A has been
set, it's possible to select the clamp model: Type = "4005"
(HT4005) or "STD" (Standard clamp).
PAG
The virtual FS key, active only when the HRM V or the HRM I
mode has been selected with the Func key, allows scrolling down
the bar graph of the harmonics window by window. Following
options are available: h02÷h08, h09÷h15, h16÷h22, h23÷h29,
h30÷h36, h37÷h43, h44÷h50
