READ CAREFULLY BEFORE
USING FOR THE FIRST TIME
Your instrument is equipped with a NiMH battery. This technology offers several
advantages:
• Long battery charge life for a limited volume and weight.
• Possibility of quickly recharging your battery.
• Signicantlyreducedmemoryeffect:youcanrechargeyour
battery even if it is not fully discharged.
• Respectfortheenvironment:nopollutantmaterialssuchaslead
or cadmium, in compliance with the applicable regulations.
After prolonged storage, the battery may be completely discharged. If so, it must
be completely recharged.
Your instrument may not function during part of this recharging operation.
Full recharging of a completely discharged battery may take several hours.
NOTE: In this case, at least 5 charge/discharge cycles will be necessary
for your battery to recover 95% of its capacity.
To make the best possible use of your battery and extend its effective service life:
• Only use the charger supplied with your instrument. Use of
another charger may be dangerous.
• Only charge your instrument at temperatures between 0° and 40°C.
• Complywiththeconditionsofusedenedintheoperatingmanual.
• Complywiththestorageconditionsspeciedintheoperating
manual.
NiMH technology allows a limited number of charge/discharge cycles depending
signicantly on:
• The conditions of use.
• The charging conditions.
Do not dispose of the battery pack with other solid waste. Used batteries
must be entrusted to a qualied recycling company or to a company
specialized in processing hazardous materials.

CHAPTER 1
INTRODUCTION
Warning
These precautions for use are imperative when using the machine. Failure to
comply with these instructions may lead to electric shocks, explosions or re.
• The operator will consult these instructions whenever the symbol
is displayed.
• If you use this instrument in a way which is not specied, the
protection which it provides may be compromised, putting you in
danger.
• When removing or inserting the battery and/or SD card, ensure that
the measuring leads, sensors and power cord are disconnected. The
unit must be disconnected and powered down.
• The unit must not be used if the “battery/SD card” housing is absent,
damaged or incorrectly tted.
• The safety of any system incorporating this instrument is the
responsibility of the system assembler.
• For your safety, only use the leads and suitable accessories delivered
with the instrument: they comply with the norm IEC 61010-031 (2002).
When the sensors or accessories of lower voltage and/or category are
connected to the unit, these lower voltages and/or categories become
applicable to the entire set.
• Before using the PowerPad®always check that the leads, sensors and
accessories are in perfect condition. If anything appears damaged
(even partially) it must be repaired or scrapped.
• Comply with the specied environmental conditions.
• It is advisable to use individual protective safety devices when the
environment in which the unit is used require them.
• This unit must be used for CAT IV installations, for voltages that do not
exceed 600VAC/DC in relation to the ground (per IEC standard 61010-
1) or for voltages that do not exceed 1000V for CAT III installations.
Never use voltage networks or categories greater than those
mentioned.
• Only use power cords and battery packs supplied by the manufacturer.
They have specic security mechanisms.
• Comply with the limits of the accessory or sensor safety mechanisms.
Do not keep hands close to unused terminals.
• Certain current sensors cannot be inserted and removed from bare
conductors under a dangerous voltage: consult the sensor’s manual
and comply with handling instructions.

CHAPTER 2
PRODUCT FEATURES
2.1 Description
The easy-to-use, compact and shock-resistant PowerPad®Model 8335 is a three-
phase power quality analyzer equipped with four current probes and ve voltage
inputs. It is intended for technicians and engineers to measure and carry out
diagnostic work and power quality work on one, two or three phase low voltage
networks.
The PowerPad’s 2GB of memory is conveniently partitioned to let you store four
different types of data, synchronized or independent of each other. You can store
up to 50 screen snapshots, up to 210 captured transients that contain four cycles
for each active input, and 10,000 alarm events from up to 40 different parameters.
You can also record trend data for days, weeks or even months.
Six access buttons quickly display the following functions. Note that these func-
tions can be accessed during a recording.
Waveforms – Display Volts, Amps, THD and Crest Factor by phase or for all
phases. You can display all the voltage inputs on one screen, phase-to-phase
or phase-to-neutral. Real-time phasor diagrams can be displayed for volts and
amps, also by phase or for all phases including phase unbalance.
Harmonics – Display Harmonics out to the 50th for Volts, Amps and VA.
Individual Harmonics are displayed as a percentage and value for Volts, Amps
and VA. Harmonic direction and sequencing can also be displayed.
Transients or Inrush Current – Set, capture and display transients. You select
the threshold and the number of transients to capture. The PowerPad®then cap-
tures four waveforms for each transient; the triggering waveform as well as one
pre-triggered and two post-triggered waveforms. As many as 210 transients each
consisting of 4 waveforms per channel for up to 8 channels can be captured.
Trend Recording – Record and display trend data at user selectable sample
rates from 1/sec to 1/15 minutes and user programmable recording periods into
2GB of memory.
Recordings can only be downloaded through the USB port. Extremely long
recordings will take a long time to download (> 2H per 100MB). Also,
keep in mind that Microsoft®Excel is limited to 10,000 lines per spread-
sheet and Access has limitations as well.
