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.
● Signicantly 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 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.

2. INTRODUCTION
2.1 DESCRIPTION
The PowerPad® III Model 8333 is a 3-phase network analyzer with a color graphic display and built-in rechargeable
battery. This instrument can be used to:
● Measure the RMS values, powers, and perturbations on electric distribution networks
● Deliver a snapshot of the principal characteristics of a 3-phase network
● Track the variations of various parameters over time
The measurement accuracy of the instrument is better than 1% (not counting the accuracy due to the current sensors).
The instrument is also very exible, with a choice of sensors allowing measurements ranging from a few milliamperes

The screen denes the current probes and ratios.
This menu enables you to dene
■ Current probes (press A)
■ Current ratios (press V or U, depending on set-up)
Figure 4-11
Press A to dene the current probes and ratios. This displays the current probe models detected by the instrument. If a
probe is detected but not managed, an error message is displayed.
For a 3-wire 3-phase set-up where only two of the three current sensors required are connected, if these two sensors are
of the same type and have the same ratio, the instrument simulates the third sensor by assuming the same characteristics
as for the two others. The third sensor will be shown in the list as either being simulated, or impossible to simulate.
The current probe choices that are available are:
MN93 clamp: 200AAC
MN193 clamp: 100 or 5AAC
SR193 clamp: 1000AAC
J93 clamp: 3500A/5000AAC/DC
AmpFlex® A193: 100A/6500A/10,000AAC
MiniFlex® MA193: 100A/
MR193 clamp: 1000A/1200AAC/DC
SL261 clamp: 100A (sensitivity 10mV/AAC/DC)
SL261 clamp: 10A (sensitivity 100mV/AAC/DC)
Three phase adapter: 5AAC
6500AC
If an MN193 clamp (5A range) or an adapter is used, the current ratio setting is proposed automatically. If an MN193
clamp (5A range), an Adapter, an AmpFlex®, a MiniFlex®, J93 or an SL261 clamp is used; adjustment of the ratio, range,
or sensitivity is proposed automatically.

■ Phases: Options are 3L, N, and 4L.
■ < or >: Determines whether the alarm condition is triggered when the measurement exceeds or falls below the
threshold alarm setting.
■ Threshold: The value that must be reached to start an alarm. For “>” alarms, the value or higher must be reached. For
“<” alarms, the value or lower must be reached. To the right of this setting is a button that displays a drop-down menu
from which you can select the appropriate unit of measurement.
■ Duration: The alarm will only be recorded if the duration of the parameter meeting the threshold criteria exceeds the
duration. The minimum alarm duration can be in minutes or seconds. In the case of Vrms, Urms, or Arms not using
neutral current, this setting can also be in hundredths of a second. For Vrms, Urms, and Arms, it can be useful to set a
duration of 0 seconds. In that case an event as short as a half cycle can be detected (8 milliseconds at 60Hz). For all
other parameters, the minimum duration that can be detected is 1 second.
■ Hysteresis: This value for alarms is set to prevent multiple recordings of an event that goes above the threshold and a
certain percentage below it at times.
Example: Alarm threshold is 100 Volts or higher, hysteresis is 1%. When the voltage goes up to 100V, the alarm condition
starts. When it goes back down to 99V, the alarm condition stops.
NOTE: You can congure alarms, recordings, Inrush, and transient searches while testing is in progress.
6.4.5 RECORDINGS
The Recordings tab shows the parameters for a recording session.
Figure 6-11
Four different congurations are available. More congurations can be saved by pressing Save to File and recalled later
by pressing Load From File.
1. Select the conguration to set up: 1, 2, 3, or 4.
2. Check the box for each parameter desired in the Data to Record section.
3. Congure the harmonic values to be recorded, if desired.
4. Choose an Aggregation Period for the recording, which sets how often the recording updates while it is running.
The Model 8333 loses its scheduled recording if it is powered OFF before the recording begins. If it is powered OFF
during the recording, a partial recording will usually still exist but with the rst letter of its name changed to “@”. The
start and end times requested for the recording might be adjusted by the Model 8333 to be in even multiples of the
averaging period. For instance, if an integration period of 10 minutes was requested, and the start time was 9:03, the
recording might not actually begin until 9:10.
