PRECAUTIONS FOR USE
This instrument and its accessories comply with safety standards IEC 61010-1, IEC 61010-031, and IEC 61010-2-032 for
voltages of 600V in category IV or 1000V in category III.
Failure to observe the safety instructions may result in electric shock, re, explosion, and destruction of the instrument
and of the installations.
● The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be
taken in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.
● If you use this instrument other than as specied, the protection it provides may be compromised, thereby
endangering you.
● Do not use the instrument on networks of which the voltage or category exceeds those mentioned.
● Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.
● Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the
insulation is deteriorated (even partially) must be set aside for repair or scrapping.
● Use only the leads and accessories supplied. Using leads (or accessories) of a lower voltage or category reduces the
voltage or category of the combined instrument + leads (or accessories) to that of the leads (or accessories).
● Use personal protection equipment systematically.
● Keep your hands away from the terminals of the device.
● When handling the leads, test probes, and crocodile clips, keep your ngers behind the physical guard.
● Use only the mains power adaptor and battery pack supplied by the manufacturer. They include specic safety
features.
● Some current sensors must not be placed on or removed from bare conductors at hazardous voltages: refer to the
sensor manual and comply with the handling instructions.
READ CAREFULLY BEFORE
USING FOR THE FIRST TIME
Your instrument is equipped with a NiMH battery. This technology oers several advantages:
● Long battery charge life for a limited volume and weight.
● Possibility of quickly recharging your battery.
● Signicantly reduced memory eect: 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 eective 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 dened in the operating manual.
● Comply with the storage conditions specied in the operating manual.
NiMH technology allows a limited number of charge/discharge cycles depending signicantly 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 qualied recycling
company or to a company specialized in processing hazardous materials.

2. PRODUCT FEATURES
2.1 DESCRIPTION
The easy-to-use, compact and shock-resistant PowerPad® III Model 8435 is a three-phase power quality analyzer
equipped with four current inputs 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® III Model 8435 has SD Card memory for storing trend data, and internal Flash memory for storing
transient, alarms, and snapshot data. 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 dierent parameters. You can also record trend
data for days, weeks, or even months. The Model 8435 is IP67 rated.
Six access buttons quickly display the following functions. Note that these functions can be accessed during a recording.
Waveforms (
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 ( ) displays 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 ( ) sets, captures, and displays transients. You select the threshold and the number of
transients to capture. The Model 8435 then captures 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
