7. POWER QUALITY
This function allows the following operations:
 display in real time the electrical parameters of a single phase system or a three
phase system (with and without neutral wire) and the harmonic analysis of voltage and
current.
 conduct a direct Energy measurement (without memorizing).
 memorize (pressing SAVE key) the sampled values of the Parameters present at
instrument input generating a "Smp" record inside instrument memory. It will be
possible to analyse the memorized data ONLY by transferring it to a PC.
 record simultaneously (pressing the START key after a proper setting): RMS values
of voltage, current, corresponding harmonics, active, reactive and apparent powers,
power factors and cos

, active, reactive and apparent energies, voltage anomalies
(voltage sag and surge) with 10ms resolution. It will be possible to analyse the
recorded data ONLY by transferring them to a PC.
It's fundamental the Instrument settings correspond to the Installation type under test and
accessories is use. For this we recommend you to check instrument's setting before
execute an ANALYSIS measurement.
Select the POWER QUALITY rotary switch position. By pressing the MENU key the
following screen will be displayed:

It’s not possible to enter the MENU during a recording or a Real Time Energy
measurement.
Generally to check instrument's settings you must check "ANALYZER CONFIG" and
"RECORDER CONFIG" items.
