A harmonic ANALYZER (option)
Harmonic analysis is a basic function for all users in the fields of
power distribution, electrical engineering, and power electronics.
The instrument can display the first 32 orders of signals having
fundamental frequencies between 40 Hz and 5 kHz. It is possible
to display the harmonic analyses of two or four channels
simultaneously.
A RECORDER (option)
For all professional users who must track variations of physical or
mechanical phenomena, a veritable high-speed digital recorder can
be incorporated in the instrument in the form of a software module.
It allows acquisition rates equivalent to as little as 500 µs between
two measurements, and the records can cover an entire month.
The users concerned will find features familiar from "Paper recorders"
and "Digital recorders", notably monitoring of thresholds and tolerance
windows with triggering of long-term storage of the phenomenon observed
(50,000 measurements) and the automatic capture of successive timestamped
faults (50 1,000-measurement windows).
The analysis can be performed on the instrument itself (even mathematical
calculations using values from more than one channel) or standard ".TXT" files
exported to a spreadsheet.
The result of the harmonic analysis is displayed in bargraph
form.
The status zone indicates:
• the total RMS voltage of the signal in V, the harmonic
factor in %
• for the selected harmonic or fundamental, the value in %
of the fundamental, the phase in ° with respect to the
fundamental, the frequency in Hz, the RMS voltage in V.
Thanks to the Probix system, the Instrument manages a great variety of sensors (voltage,
current, temperature, 0-10V, 4-20mA, etc.) and displays the signals in their original
physical magnitude (scale and unit).
The measurement cursors (the last acquisition and the mobile cursor) can be used with the
zoom to perform a fine analysis of the signals being acquired or already acquired.
RECORDER (option)
