2. GENERAL DESCRIPTION 

2.1. INTRODUCTION 
The PQA400, PQA823 and PQA824 meters permits a completely new approach to the 
world of electrical measures on network quality. In fact the computer assisted instruments 
along with Windows CE technology permit an easy and widely fast analysis of a huge 
quantity of data, which would be impossible with any other system. 
This user’s manual is common to all meters, the PQA823 and PQA824 are indicated as 
“PQA82x” and the differences between meters’, if necessary, are clearly declared in 
manual. Each model is generically called “meter”. 
 
2.2. FUNCTIONS 
This meter are able to performs: 

  Real time visualization of numeric values of any electrical parameters of a single phase 

and three-phase 3-wire or 4-wire systems, harmonic analysis of voltages and currents 
up to 49

st

 order, Voltage anomalies (surge and dips) with 10ms resolution, Flicker (Pst, 

Plt) of input voltages, voltages unbalance, inrush current measurements (PQA82x 
models only) and fast voltage transients analysis with 5

s resolution (PQA824 only). 

  Real time display of any input signal waveform, histogram graphics of harmonics 

analysis and vectorial diagrams of mutual angles between voltages and currents. 

  Recording (by pressing GO/STOP  key) of this values: TRMS values of voltages, 

currents, corresponding harmonics, active, reactive and apparent powers, power 
factors and cosphi, active, reactive and apparent energies, voltage anomalies. It will 
be possible to analyze the recorded data ONLY by transferring them to a PC. 

 Saving (by pressing SAVE key) of a “Instant” sampled of instantaneous values of any 

parameters present at instrument input inside memory. It will be possible to analyze 
the memorized data ONLY by transferring them to a PC. 

 
2.3. INITIAL 

SCREEN 

When turning on the instrument by pressing ON/OFF key, this below screen will appear for 
a few seconds:
