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.

III Model 8435
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 2GB of 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 different 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 ( ) displays 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 ( ) 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
channel for up to 8 channels, can be captured. Inrush current is measured when the power is rst turned on. Depending
on the type of load, the Inrush current may be very high for some time when compared with steady state current later on.
Trend ( ) records and displays trend data at user selectable sample rates from 1/sec to 1/15 minutes and user
programmable recording periods into 2GB of memory.
Alarm Events ( ) provides a list of the alarms recorded according to the thresholds programmed during conguration.
Power/Energy ( ) records and displays power levels and associated parameters (power factor, displacement, and
tangent).
Recordings can only be downloaded through the USB port. Extremely long recordings will take a long time to download (> 2H
per 100MB).
