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.
• Significantly 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 defined in the operating manual.
• Comply with the storage conditions specified in the operating
manual.
NiMH technology allows a limited number of charge/discharge cycles depending
significantly on:
• The conditions of use.
• The charging conditions.
Please refer to § 7 for correct replacement of the battery.
Do not dispose of the battery pack with other solid waste. Used batteries
must be entrusted to a qualified recycling company or to a company
specialized in processing hazardous materials.

3.2.4 Accuracy Specifications of the Current Probes
These characteristics are stated after linearization. The errors of the sensors are
compensated by a typical correction inside the instrument. This typical correction
is in phase and in amplitude according to the type of sensor connected (detected
automatically) and the gain of the current acquisition chain used.
The measurement error in RMS current and the phase error are additional errors
(they must therefore be added to those of the instrument alone) stated as influences on the calculations performed by the analyzer (powers, energies, power
factors, tangent, etc.).

5.7 Inrush Mode (starting current)
This mode is used to record the waveform of the current on 229,376 samples, at
256 samples per period (17.92s of recording for a 50Hz signal).
Recording is triggered automatically when the starting of a motor is detected. The
beginning of the motor starting search can be triggered in delayed mode (starting
date and time programmed by the user). The search can be stopped manually if
desired.
Once the recording has been done, the PowerPad® Jr. displays the waveform of
the current. The user can then move along the curve using a cursor and zoom in
on features of interest.
The following information is available:
• Instantaneous value of the current at the time indicated by the cursor.
• Maximum instantaneous value of the current (over the entire start).
• RMS value of the half-period (or lobe) of the current on which the cursor
is placed.
• Maximum half-period RMS value of the current (over the entire start).
• Starting time and duration of the starting of the motor.
WARNING: The voltage must be present before the motor is switched ON in order
to have a stable and correct frequency synchronization.

6.3.4 Alarm Conditions Configuration
The Alarm Conditions window allows you to set up 10 alarm configurations.
Figure 6-8
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: If the alarm threshold is 100V 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.
Schedule Alarm Search: When this check box is checked, an alarm is ready to be
scheduled. Once checked, the End Alarm Search button will appear.
End Alarm Search: This button will stop all alarms in progress.
Capture Parameter: The alarm will be triggered based on the value of the selected
parameter.
Choices include:
•
•
•
•
•
•
None: no alarm
Vrms: voltage root mean squared
Arms: current root mean squared
VPST: voltage short term flicker
Vcf: voltage crest factor
Acf: current crest factor

1.877.766.
Once a parameter is selected, a threshold window will open allowing you to set
the trigger value.
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 or Arms not using neutral current, can
also be in hundredths of a second.
For Vrms 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.
NOTE: It is possible to check for alarms, records and search for transients at the
same time.
6.3.5 Recordings Configuration
The Recording window shows the dialog box used to configure the parameters for
a recording session.
Figure 6-9
Four different configurations are available. More configurations can be saved by
pressing “Save to File” and recalled later by pressing “Load From File”.
1. Check the configuration you wish to set up: 1, 2, 3 or 4.

2. Check all the parameters you wish to record by clicking on each one.
3. Configure the harmonic values to be recorded, if desired.
It is also possible to record up to 2 of 3 types of harmonic data, voltage (Vh),
current (Ah) and power (VAh).
For each selected harmonic data type, you can choose a range of harmonics
to record from the 1st to 50th. You can further limit that range to only include
odd numbers by checking the box for “Odd Harmonics Only”.
End Recording: Ends any recording in progress or any future recording.
Clear Entries: Clears the data entered in the new recording window. It does not
cause any changes to the PowerPad® Jr.
Write Changes and Start New Recording: Causes the PowerPad® Jr. to schedule a new recording.
NOTE: The PowerPad® Jr. loses its scheduled memory 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 first letter of its name changed to “@”. The start
and end times requested for the recording might be adjusted by the PowerPad®
Jr. to be in even multiples of the averaging period. For instance, if an integration
period of 10 minutes were requested, and the start time was 9:03, the recording
might not actually begin until 9:10.
If OK or Apply is pressed, the following screen appears:

6.3.7Monitoring
The EN50160 standard defines limiting values and permissible variations of the
voltage quality for the European Community. It defines which parameters are
relevant, and how are they measured. Continuous or random sampling control
of the voltage quality provides the supplier of electric energy with a reliable basis
when dealing with network problems, and it contributes to quality assurance.
The purpose of the EN50160 standard “Voltage characteristics of electricity supplied by public distribution systems” is to specify the characteristics of the supply
voltage with regard to the course of the curve, the voltage level, the frequency and
symmetry of the three phase-network at the interconnecting point to the customer.
The goal is to determine limiting values for regular operating conditions.
However, facility defects may lead to major disturbances in the electricity distribution
supply network. Accordingly, the standard establishes these values as limiting
values, which are not allowed to be exceeded on the high or low side during 95%
of the controlled period, typically one week.
Figure 6-12
Configure and start an EN50160 test of line quality. It is recommended that a brief
test of 10 minutes or shorter be done first, to verify the connections and parameters of the test are correct. Only then should the 1-week test be done.
If neither of the voltage profiles are chosen, a field appears to enter the nominal
voltage. The frequency is not asked for, since it will be asked for when the test
result is downloaded.
Follow the instructions in the dialog box to set up and run this special test. Press
the Help button for further instructions.

6.5.6 Saving Real-time Measurements
Real-time data received from an instrument can be saved directly into a recording session database. This differs from the process of downloading and saving
recorded data in that the measurements are stored on the computer as the instrument measures them. These measurements are not necessarily being stored
within the instrument. However, the instrument may be configured to record at
the same time real-time measurements are being received from the instrument. In
which case, two copies of the measurements will be stored. One copy is stored on
the local computer and the other in memory within the instrument.
To Save a Real-time Measurement:
1. From the Realtime Trend window, check the “Rec to PC” checkbox.
2. In the Save As dialog box that appears, specify the type of file to save in the
“Save as Type” field. The choices are .dvb (DataView database), .xls (Excel
spreadsheet), or .csv (Comma Separated File). Specify the name of the file
by typing it into the File name field, select the desired location to save the file,
then click Save to save the file.
3. When the “Rec to PC” option is unchecked the file can be opened by selecting
Yes from the View Saved File dialog box.

The Session Properties dialog box allows you to specify the Operator, Site and
Custom parameters that are to be saved with recorded data. These parameters
are used when generating reports.
The Operator and Site tabs allow you to maintain lists of operators and sites,
saving you time when specifying parameters for reports.
On the left of the Operator and Site tabs is the list of previously defined Operators
and Sites. On the right of the Operator and Site tabs is the individual parameters
that will be saved in an associated database. Only a single set of operator and site
fields are saved in the recording database.
The Custom tab contains a list of user defined parameters. Along side each user
defined parameter is a check box. Items that are checked will be added to an
associated database. Only a single set of Custom parameters can be maintained
(unlike the Operator and Site lists). The Custom tab allows you to specify any user
defined parameters (in addition to the comments field of the Site tab) that are to be
used in displaying a report.
In addition to the pre-designed report templates, DataView® allows you to totally
configure reports to your needs. Refer to the DataView® HELP file on “Templates” to learn more about templates.

MATHEMATICAL FORMULAS FOR VARIOUS PARAMETERS
NOTE the following abbreviations used in this section:
NSHC = number of samples per half cycle (between two consecutive
zeros)
NSC = number of samples per cycle
NSS = number of samples in a second (multiple of NSC)
V = voltage phase to neutral
U = voltage phase to phase
Network Frequency
The sampling is locked to the network frequency so as to provide 256 samples per
period (NECHPER) from 40 to 70Hz. This locking is essential for the calculations
of the reactive powers, the calculations of levels and angles, and the calculations
giving the harmonic magnitudes.

Harmonic Calculations
These are done by 1024-point FFT (4 periods) without windowing (cf. IEC 1000-47). From the real and imaginary parts, the levels Vharm and Aharm are calculated
(with respect to the RMS value of the fundamental) and the angles Vph and Aph
are calculated (phase shift with respect to the fundamental).

Hysteresis
Hysteresis is a filtering principle, often used after the threshold detection has
occurred. A correct setting of hysteresis value will avoid repeated triggering when
the measure is varying close to the threshold.
The event detection is activated when the measure is going over the threshold but
it can only be deactivated if the measure goes under the threshold minus the value
of the hysteresis.
The default hysteresis value is 2% of the reference voltage but it may be set in the
range of [1%, 5%] depending of the voltage stability on the system.
