8.3. ANALYZER FUNCTIONS
For a simple usage, the main working mode of the ANALYZER mode can be
selected by means of F3 and F4.
"
VOLTAGE" function:
to be used to display
voltage and corresponding
harmonics (see paragraph 8.4)
"
CURRENT" function:
to be used to display
current and corresponding
harmonics (see paragraph 8.5)
" POWER" function: it permits to display all the parameters measurable by
the instrument: voltage, current, active, reactive and
apparent power, power factor, cos
ϕ and energy (see
paragraph 8.6)
" ENERGY" function: to be used to display active, reactive and apparent
power, power factor, cos ϕ and energy (see paragraph
8.7)
More practically, we may schematise the right procedure of use the
ANALYZER function
as follows:
1. Check and eventually modify the "ANALYZER CONFIG" settings of the instrument
2. Using
F3 and F4, select the type of measurement to be taken
3. Connect the instrument to the electrical system to be tested
4. Evaluate the values of the parameters under test
5. If you want to record:
a) Decide what to record
b) Press
MENU and check if the "RECORDER CONFIG" settings meet your
requirements.
c) Consider Typical Configuration recording (see paragraph 10.2).
6. Connect the External Power Supply A0050 (optional)
7. Start the recording by pressing START/STOP.
8.4. "VOLTAGE"
FUNCTION
This function permits you to display in real time the RMS value of AC/DC voltage,
the peak, the Thd value (see paragraph 16.11), the waveform and the harmonic
spectrum of the voltage.
8.4.1. Symbols
The VOLTAGE position has three working modes:
METER
WAVE
HARM
These modes will be described in detail in the next paragraphs.
The used symbols are described below:
Symbol Description
V1
Voltage RMS value
Vpk1 Peak value of the voltage
h01
÷ h49
Harmonic 01
÷ Harmonic 49.
ThdV Factor of total harmonic distortion of the voltage (see paragraph 16.11).
freq Network frequency
