Principal parameters measured:
- TRMS AC+DC voltage: single voltage up to 480 V; phase-phase
voltage up to 600 V
- TRMS AC, AC+DC current up to 3000 A (according to sensors used)
- Peak voltage and current
- Frequency from 40 to 70 Hz
- Active, reactive and apparent power per phase and their
summation
- Active, reactive, consumed and produced energy.
- Harmonics for voltage, current or power up to the 50th order
Regardless of the screen, the synergy between the display and the
keyboard is very efficient.

Along with its high-performance
measurements, the PA8332 P8334 is ergonomic and offers a
user-friendly operating mode.
A keyboard divided into easily
identifiable zones
The keys, which are clearly
identifiable
by their shapes, positioning and
pictogram,
make mastering the instrument's
functions
rapid and easy.

Very structured display modes for 3 distinct stages
"Observation" stage:
In this mode, three types of
representations are possible: graphic, table, vectoral. RMS measurements
in U and I. PEAK, MIN, MAX, AVG, KF, Pst, CF, phase shift, unbalance
measurements...
|
"Diagnosis" stage:
Power / Energy Mode
This mode displays all of the values relative to the power and
energy. The Start and Stop keys activate and deactivate the summation of
energy.
Measurements for:
W, VAr, VA
Wh, VArh, VAh
PF, DPF or cos and tan
Harmonics Mode
Global THD and phase by phase in V, I, VA as % or RMS value and
harmonics phase shift.
Only the PA8334 model
offers the harmonics function in VA and the "
expert mode" . This mode provides an
analysis of harmonics influence on neutral heating or rotating machines.

With the
around-the-neck
holder, making measurements is
easy: operating
the instrument and
reading the displays
at the same time.

"Monitoring" stage:
Alarms Mode
The alarms are defined during the instrument's configuration. The
alarm mode displays all threshold events which occur during the
measurement period. Automatic time and date recording of the alarm, the
maximum corresponding value, and the duration of the event.
Recording Mode
All desired parameters are saved with their visual graphics during a
recording. Note that a bar graph located at the top of the window gives
the total recording period, programmable recording period and storing
rate.
Transient Mode
The transient mode captures changes of the voltage and current with
triggers on thresholds. Representation over 4 periods of the captured
event at 256 counts / period, also available with zoom.

Direct Function Keys:
Configuration
The simplicity of the instrument's set-up is enhanced by the use of
graphic representations: type of clamp, connection, color of phases,
parameters to record…
Printing
The PA8332 can be connected directly to a printer for immediate
screen printing.
Screen Shot
Press this key to make a copy of the screen. Storing the viewed
screen is automatic with date and time recording. Up to 12 screen
recordings (PA 8334).
Help
