ANALYSER FUNCTIONS
For a simple usage, the main working mode of the ANALYSER mode can be
selected by means of F3 and F4.
"VOLTAGE" function:
"CURRENT" function:
"POWER" function:
"ENERGY" function:
More practically, we may schematise the right procedure of use for the ANALYSER
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 MAR#### (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 REF _Ref530398168 \r \h 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 symbols used 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
to be used to display voltage and corresponding
harmonics (see paragraph 8.4)
to be used to display current and corresponding
harmonics (see paragraph 8.5)
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)
to be used to display active, reactive and apparent
power, power factor, cos ϕ and energy (see paragraph
8.7)
