2. FEATURES

2.1 Description

The Power & Energy Logger Model PEL 105 provides all the necessary functions and features for recording power/energy
data for most 50Hz, 60Hz, 400Hz, and DC distribution systems worldwide. The instrument is designed for full outdoor or
indoor use, resistant to both water (IP67) and sunlight (UL746C f1).

The instrument measures phase-to-phase (U12, U23, U31), phase-to-neutral (V1, V2, V3) and neutral-to-ground/earth (VNE)
voltage up to 1000V in measurement Category IV, with pollution degree 4 (IEC 61010-1 Ed3). The instrument also measures
phase (I1, I2, I3) and neutral (IN) current, using a variety of external current probes/sensors.

A total of 17 types of electrical hookups are supported, including single-phase, split-phase, 3-phase 3-wire, 3-phase
4-wire, open, and DC 2-, 3- and 4-wire.

This measurement data is then used to calculate:

■ Power (VA, W, and var )

■ Energy (VAh, Wh (source and load), and VArh (4 quadrants)

■ Power Factor (PF), Cos ϕ, and Tan ϕ

■ Crest Factor

■ Total Harmonic Distortion (THD) for voltages and currents

■ Harmonics from the fundamental signal up to the 50th order for 50/60Hz voltages and currents

■ Frequency measurements

■ RMS and DC measurements @ 128 samples/cycle (each phase simultaneously)

The instrument can be connected to a computer running DataView data analysis software via Wi-Fi, Bluetooth©, network,
USB, or point-to-point Ethernet cable. The DataView PEL Control Panel on the computer can view real-time data, start and
stop a recording session, download previously recorded sessions stored on the instrument for further analysis and report
generation, and set configuration variables.

Other features include:

■ Measurements are sampled every 200ms and 1s, and can be aggregated from 200ms to 1 hour and stored in
a removable SD card or SDHC card (up to 32GB). This provides high data resolution and detail, especially for
detecting short-term electrical phenomena. For 50 and 60Hz systems, 200ms aggregation is calculated every 10
or 12 cycles, respectively. For 400Hz systems, aggregation is performed every 80 cycles.

■ Aggregated harmonics represent the minimum and maximum values of aggregated quantities for a given
duration. These values can be displayed on the LCD front panel display, or on the computer via the DataView
PEL Control Panel

■ The instrument can be powered from line voltage terminals or an AC/DC power adapter.

2.3 Input Terminals

The instrument provides four current and five voltage input terminals for connecting to the electrical network under test.
These terminals are threaded to provide IP67 water-tight connections.

The instrument ships with five female “banana” voltage terminals that can be screwed onto the threaded voltage terminals.

3. Voltage terminals

The number and configuration of probes and voltage leads depend on the hookup type. To help organize these connections,
12 sets of color-coded rings and inserts are supplied with your instrument. Use these ID markers to identify the leads and
terminals.

■ Detach the appropriate inserts and place them in the holes provided over the terminals (larger inserts for current
terminals, smaller inserts for voltage terminals).

■ Clip the rings of the same color to the ends of the lead you will connect to the terminal.

3. SET UP & CONFIGURATION

Before using the instrument for the first time, ensure the battery is fully charged (see § 3.2) and that the instrument is ready
for operation. You must also configure the instrument for the hookup type appropriate for the electrical distribution system
under test.

NOTE: Before changing any setup or configuration setting, ensure that no recording is active or pending on the
instrument.

3.1 Powering the Instrument

The instrument can operate on three different sources of power:

■ External power provided by plugging into an AC outlet with the AC adapter. When you connect the instrument to

an AC outlet, it automatically turns ON. The instrument will always run on external AC power when plugged in,
even if phase power and/or battery power are also available.

■ Phase power provided through line voltage at the terminals. If AC wall power is disconnected, the instrument

runs on phase voltage power if it is available and enabled.

■ Battery backup power. If neither external AC power nor phase voltage is available, the instrument runs on battery

power.

3.1.1 Phase Voltage Power

Powering the instrument through phase voltage power requires no special preparation or equipment; simply connect two
voltage leads to an AC power line, connect the leads to the instrument using any available voltage terminals (see § 3), and
unplug the external AC adapter if connected. By default, the instrument will immediately begin drawing phase power from
the line.

The Power button glows green when the instrument is running on phase power. In this situation, the instrument cannot
be turned OFF via the button.

Note that you cannot power the instrument from a DC network. Also note that if the AC adapter is plugged in, the instru­ment will use this source instead of phase power.

You can disable the phase power feature by pressing and simultaneously for two seconds. When you do this,
blinks red once every two seconds, indicating the instrument cannot run on phase power. Pressing and simulta-

neously for two seconds re-enables this feature. You can also disable and enable this feature through the DataView PEL
Control Panel (see § 6).

Figure 5

3.3 Turning the Instrument ON/OFF

■ Connect the supplied power cord to the instrument
and AC power. The device will automatically turn ON.

■ The LED lights; it will go out only when the
battery is fully
charged.

■ A low battery charging takes approximately 5 hours.

Fully charging the battery may take up to 5 hours if the
battery is at or near complete discharge. If after 5 hours
the LED does not turn OFF, operate the instrument on
battery power until the battery runs low, and then repeat the
charging procedure.

In normal operation, a fully charged battery will provide
power for up to one hour before requiring another charging
session (although this period may be shorter if the instru­ment is actively using Bluetooth or Wi-Fi to communicate).
The LED glows red when the battery is low and in need
of charging.

3.3.1 Turning the Instrument ON

3.3.2 Turning the Instrument OFF

The procedure for turning OFF the instrument depends upon the power source. First check to see whether or not a record­ing is scheduled or in progress (the LED blinks twice every five seconds when a recording is active). If so, either stop
the recording, or wait until it is finished. Then do one of the following:

In addition, the instrument includes a feature that automatically turns it OFF after a period of inactivity when running on
battery power. This period, which is defined through the PEL Control Panel, can be set to 3, 10, or 15 minutes. It can also
be disabled.

■ On AC power or phase voltage power, the instrument automatically turns ON when you connect it.

■ On battery power, you must press for two seconds to turn ON the instrument.

■ AC power (indicated when the LED is lit): Unplug the AC power adapter, and then press for two

seconds. When all LEDs light up simultaneously, release .

■ Phase voltage power (indicated when glows green): Disconnect the voltage terminal leads from the
instrument, then press for two seconds and release it when all LEDs light up simultaneously.

■ Battery power: Press for two seconds and release it when all LEDs light up simultaneously.

4. OPERATION

4.1 Hooking Up to the Distribution System

The Model PEL 105 works with a variety of current probes and sensors. Choosing which type to use depends on the cur­rent to be measured and the diameter of the electrical cables. Each probe and sensor comes with its own documentation,
which you should consult before connecting to the instrument.

The instrument may be supplied with four water-tight AmpFlex® Model A196-24-BK current probes. This 24” flexible probe
measures the current in a cable without opening the circuit. The probe also comes in a 36” length (A193-36-BK). Their
performance specifications are otherwise identical; although the A193-36-BK is not water-tight.

To connect the probe to the electrical network under measurement, do the following:

1. Connect the probe lead onto the appropriate current terminal. Which terminal to use depends on the hookup
type, as explained later in this section. Note: When using AmpFlex A196-24-BK probe, be sure to screw the lead
onto the threaded terminal to ensure water-tight (IP67) operation.

2. Open the probe by pressing the release levers on the side of the coupling and pulling out the end.

3. Wrap the probe around the electrical cable to be measured.

4. Close the probe by inserting the end back into the coupling.

This is the basic connection procedure for flexible loop probes. Clamp-on probes require a similar connection process.

The following table provides measurement specifications for supported probes and sensors. For detailed probe/sensor
specifications, see § 7.9.

labels identify the input terminals functions. For example, I1 connects a current probe/sensor to line 1; I2 connects to line
2, and so on.

The following instructions assume you will use the neutral current terminal and the ground/earth voltage terminal. Use of
these terminals is not strictly required; however they provide a higher level of accuracy when used.

For all hookups, ensure that the arrow on the probe is directed towards the load (for example, see Figure 13). This provides
proper phase angle for power measurements and other phase-sensitive measurements.

4.2 Viewing Data

The PEL 105 provides four data viewing modes:

■ Measurement mode displays real-time data currently being measured by the probes/sensors. This includes
voltage, current, power, frequency, power factor, and tangent angle.

■ Energy mode displays energy use, including reactive energy, apparent energy, and kilowatt hour.

■ Harmonics mode displays harmonics for currents and voltages.

■ Maximum mode displays the maximum values for measurement and energy values.

Press ◄ or ► to navigate to the desired mode. When a mode is selected, a box appears around its icon at the bottom of
the display screen (Figure 5). Each mode provides a set of screens for viewing data. Press ▲ or ▼ to navigate through
these screens. Some of these screens include additional information which you can view by pressing . For example,
several Measurement mode screens display phase angle information when you press . Pressing ▲ or▼ while viewing
an additional information screen returns to the previous screen.

The sequence of screens, and the information each one shows, is dependent on the electrical hookup setting.

The following tables list the screens available in Measurement, Energy, Harmonics, and Maximum modes. For each screen,
the following information is displayed:

■ Image of the screen.

■ Title of screen, summarizing the information it displays.

■ Button to push to view the screen, shown to the left of the screen shot.

■ A list of the variables displayed on the screen, shown to the right of the screen image. These variables are
defined in the Glossary.

5. RECORDING DATA

The instrument can record measurement data and store the results. You can start a recording immediately, or (using the
DataView PEL Control Panel) schedule one with a defined start date/time and duration. The session can then be down­loaded for viewing, analysis, and distribution.

5.1 Recording Session Overview

Recording sessions are configured through the PEL Control Panel. This provides a number of recording options, such
as selecting which data to include in the recording, the demand (aggregation) period, and recording schedule. This also
includes changing the instrument’s date and time, if required (see § 6.3). After you complete a recording session, you can
add information such as session name, the operator who conducted the recording, and the location where it took place. In
addition, the PEL Control Panel enables you to download recordings and clear them from the instrument.

Typically, recording sessions are started, stopped, and scheduled through the PEL Control Panel. You can also start and
stop a recording session on the instrument itself (see § 5.2). You can also set the aggregation period for a recording, as
explained in § 3.6.4.

Recording sessions are stored in the instrument’s SD card. The memory required for a recording session primarily depends
upon the duration of the recording and the storage period. Recording rates for the different types of session data are as
follows:

■ 200ms trends: 92MB per day

■ 1-second harmonics: 91MB per day.

■ 1-second trends: 36MB per day.

■ Aggregated trend: 1.7MB per day for 1 minute periods. For longer periods, this rate is divided by the period in
minutes. For example, for an aggregation period of 10 minutes, the rate will be 0.17MB per day; for 15 minute
periods this is 0.113MB per day, and so on.

■ Aggregated harmonics: 1.6MB per day for 1 minute periods. (For longer periods, use the same formula
described above for aggregated trend data.)

For instance, a five-day session recording aggregated trends and harmonics with a 15 minute demand period, 1 second
trends, and 1 second harmonics would consume approximately 636MB of storage.

The recommended maximum recording times for a single session on an instrument are:

■ 21 days when recording 200-ms trends and 1-minute aggregated data (trend and harmonics).

■ One month when recording 1-minute aggregated data, 1-second trends, and 1-second harmonics.

■ 15 weeks when recording 1-minute aggregated data and 1-second trend data but not harmonics.

■ Three years when recording only 1 minute aggregated data (including aggregated harmonics).

■ Multiple years when recording only 15-minute aggregated data (without aggregated harmonics).

Other recommendations include:

■ Do not store more than 32 recording sessions on the SD card.

■ For recordings with harmonics or with a duration longer than one week, use class 4 or higher SDHC cards.

■ Avoid downloading large sessions via Bluetooth, because this may require many hours to finish. If Bluetooth is
the only communication method available, you can reduce the amount of data to be downloaded by selectively
excluding 200ms trends, 1 second trends, and harmonics from the download. Doing so reduces the data
downloaded from a 30 day recording with 15-minute aggregation to 3.4MB. (You can choose which recorded
data to include/exclude in the download via the PEL Control Panel.)

5.2 Starting and Stopping a Recording

Before starting a recording, ensure that the instrument is not currently locked (the word LOCK appears on the screen in
Configuration mode). The instrument cannot begin a recording when it is locked. The instrument is locked when:

■ Being configured via the PEL Control Panel.

■ Disabled through an option in the PEL Control Panel (see § 3.6).

■ A recording session is already in progress. Note that in this case the button remains active so you can stop
the recording. However, you cannot start a new recording if one is in progress.

If any of these situations is in effect, take appropriate action as necessary to unlock the instrument. Then check the SD
card LED.

■ If the LED is green, the SD card is ready to store recordings.

■ If the LED glows steady red, ensure that:

- The SD card is installed. If not, consult § 2.7.

- The write-protect sliding tab on the card is in the “unlock” position (towards the metal contacts).

- The SD card is formatted. Formatting can be performed either through the PEL Control Panel, or through a
Windows command on your computer.

Note that the LED briefly blinks red when the card is initializing.

■ If the LED blinks alternately red and green, the SD card is full. Download any data you want to save to your
computer, then erase the content of the card through the PEL Control Panel.

When the LED indicates the SD card is ready, you can begin recording. To do this through the PEL Control Panel,
follow the instructions provided in the PEL Control Panel Help system. To record through the instrument user interface, do
the following:

1. Press and hold it down until the LED lights. Then release .

2. The LED should now blink twice every five seconds, indicating a recording is in progress.

3. To stop a recording, press and hold it down until the LED lights up, then release .

To view the recording session, connect the instrument to your computer running DataView (see § 6).

6. DATAVIEW® & PEL CONTROL PANEL

DataView enables a computer to connect to and interact with a variety of AEMC instruments, including the Model PEL

105. As its name implies, the primary purpose of DataView is to view data that has been recorded by the instrument and
display it as a report.

With DataView, you can:

■ Connect the instrument to a computer. This connection can be through USB cable, LAN network, direct Ethernet
connection, Wi-Fi, or Bluetooth.

■ Display and analyze real-time data on the computer via a frames style interface.

■ Download previously recorded data from the instrument. You need DataView to view recording sessions, since
these sessions cannot be displayed through the instrument’s interface.

■ Start, schedule, stop, and cancel a recording session.

■ Configure a wide variety of instrument settings.

■ Perform instrument maintenance such as formatting the SD card and erasing its content.

■ Generate reports for viewing and printing the data, using standard templates or ones you customize to your
requirements.

DataView includes a core set of features used by all instruments. These features are designed for viewing data, and for
opening, creating, and saving reports. DataView also includes components called Control Panels for interacting with the
instrument. A Control Panel lets you connect to the instrument, download data, and configure the instrument’s settings.
Each AEMC product family has its own dedicated Control Panel; you select the one(s) you need during DataView installation.

For example, DataView includes the PEL Control Panel specifically designed for working with Model PEL Series instruments.
The PEL Control Panel provides all the features available in the instrument’s user interface, as well as many additional
features.

8. MAINTENANCE & TROUBLESHOOTING

There are several routine maintenance tasks you should perform periodically to ensure optimal operation of your instru­ment. In addition, the instrument may exhibit unexpected behavior that requires troubleshooting.

This chapter explains procedures you can perform to maintain the instrument and correct issues you may encounter.

8.1 Maintenance

Instrument maintenance tasks include:

■ Erasing and upgrading the SD card

■ Upgrading to the latest firmware revision

■ Maintaining the batteries

■ Cleaning the instrument

The following sections explain how to perform these tasks.

8.1.1 Erasing and Upgrading Memory

When the SD card LED either (1) blinks alternately red and green, or (2) blinks green once per second, the SD card
is either full or does not have enough remaining space to store the scheduled or in-progress recording session. In either
case, you must erase the SD card to ensure sufficient storage capacity for future recordings. This is done via an option in
the PEL Control Panel.

NOTE: Erasing the SD card deletes all the records stored in memory. To save one or more recording sessions, you
must download the session(s) to the computer.

You can remove the 8GB SD card that comes with the instrument and replace it with an SD card with up to 32GB storage.
To do this:

1. Remove the existing SD card from the instrument by pressing down and then releasing it. The card will pop up,
allowing you to pull it from the card slot.

2. Check the replacement card to ensure its write-protect sliding tab is in the “unlock” position (towards the metal
contacts).

3. Insert the SD card into the slot, with the metal contacts facing towards the top of the card.

4. Press the SD card into the slot until it clicks in place.

5. If necessary, format the card by connecting the instrument to a computer running the PEL Control Panel and
selecting the Format SD Card option.

8.1.2 Upgrading Firmware

Periodically AEMC may release new firmware for the PEL 105. This firmware controls the features and functionality of the
instrument.

We recommend checking for firmware upgrades on a regular basis, to ensure your instrument has the most current version.
The easiest way to do this is from the PEL Control Panel. The Help menu in the Control Panel includes the option Update.
When you click this option, the Control Panel automatically checks to ensure you have the latest version of firmware, and
displays a message informing you whether or not your firmware is up to date.

Another way to see the firmware irevision number is to open Information mode and press ▼ to navigate to the Firm­ware screen:

Figure 35

To check the firmware revision and download a newer version, connect the instrument to your computer with the USB
cable, and ensure the instrument is powered ON. (A USB connection is required; you cannot update firmware using any
other connection type.) Then proceed as follows:

1. From the computer, open the AEMC Instruments web site (http://www.aemc.com) and click the link labeled
Software and Firmware Updates.

2. In the Firmware Downloads section of the Downloads page, find the entry for PEL 105 firmware. This entry
includes a link to the firmware, along with the firmware revision number and its release date. Compare this
revision number to the one listed in the Firmware screen. If the revision numbers are the same, you do not need
to upgrade. If the revision number listed in the Downloads page is more recent than the number listed on the
instrument, click the PEL 105 firmware link.

3. The PEL 105 Firmware page appears. This lists the latest released version of the firmware. Firmware can be
downloaded in either .exe or .zip format. The .zip version is for systems whose anti-virus software prevents the
downloading of .exe files. If you download the .zip version, you may need to extract the .exe file from it before
you can use it to upgrade your firmware.

Download the selected file. The exact steps for downloading are browser-specific. For example, in Microsoft
Internet Explorer you are given the option of opening or saving the file (for .zip) or running or saving the file (for
.exe). In either case, click Save.

4. After the file is downloaded, open and run it. This process is also browser-specific. For example, if you use
Microsoft Internet Explorer Windows to download the file in .exe format, click Run. Then skip the remainder of
this step and go to step 5 below. If you use IE to download the file in .zip format, click Open and double-click the
file PEL_Firmware.exe. (You may see a security warning; if so click Run.)

5. The Flash Upgrade Utility opens. Select the language from the drop-down list and click Next.

6. The next screen that appears enables you to select the instrument in which you want to upgrade the firmware. If
the instrument does not appear in the list, ensure that it is powered ON and connected to the computer via USB
cable. Then click Refresh. When the instrument’s name appears in the drop-down list, select it and click Next.

7. Click the Program button to initiate the update. A status bar in the Flash Upgrade Utility screen tracks the
progress of the update.

8. When the update is complete, a message appears in the Flash Upgrade Utility screen informing you of this.

8.1.3 Battery Maintenance

The instrument is equipped with a NiMH battery, which provides approximately one hour of power. After prolonged stor­age, the battery may be completely discharged. If so, it must be completely charged. This requires approximately 5 hours.
(See § 3.2.)

To make the best possible use of your battery and extend its effective service life:

■ Only charge the battery at temperatures between -20° and 55°C (-4° and 140°F).

■ Comply with the instrument usage and storage conditions defined in § 1.

Note that you cannot change the battery. This must be done at an authorized AEMC Service Center as part of the instru­ment’s regular maintenance.

8.1.4 Cleaning the Instrument

The instrument should be cleaned periodically. This keeps the LCD clear and easily viewable, and also prevents dirt and
grease buildup around the instrument’s buttons and input terminals.

The body of the instrument should be cleaned with a damp and soapy cloth. Do not submerge the instrument in water. Do
not use solvent.

Before cleaning, disconnect all input(s) to prevent possible electric shock.

CAUTION! Risk of Electric Shock.

8.2 Troubleshooting

This section describes how to correct several potential issues you may encounter. These include:

■ The instrument does not turn ON when you press the Power button.

■ The instrument turns ON but does not function.

■ You cannot configure settings through the instrument’s front panel interface.

■ You cannot start a recording session.

■ Recording sessions end before the specified end date and time.

■ You cannot connect to a computer.

■ The instrument does not turn OFF when you press .

The following sections explain some of the possible causes for these issues and how you can address them. If you perform
these troubleshooting actions but the issue still persists, or if you encounter a problem not covered in this section, please
contact AEMC Technical Support.

8.2.1 Instrument Does Not Turn ON

The most common cause of failure to power ON is a completely discharged battery. Connect the instrument to an external
power source, either external AC power or phase power. The instrument should immediately turn ON, and the Battery
LED should glow yellow and blink indicating the battery is recovering from a full discharge.

If the instrument does not turn ON when connected to external power, contact AEMC Technical Support.

Power & Energy Logger Model PEL 105

8.2.2 Instrument Turns ON but Does Not Function

If the instrument has been stored in a cold and damp environment, condensation may form inside. This can short internal
circuitry, preventing the instrument from operating normally. In this case, turn OFF the instrument and place it in a warm,
dry environment for several hours. Then turn the instrument ON and try navigating through the screen interface to deter­mine whether or not it has been restored to normal functionality.

8.2.3 Cannot Configure the Instrument

Several conditions may cause some or all configuration options to appear disabled, or function in unexpected ways. For
example, when the instrument is locked or when it is recording data, none of the Configuration mode options is enabled.
Instead, the word LOCK appears on the LCD when you enter Configuration mode.

The instrument is locked when it is being configured through the PEL Control Panel Configure Instrument dialog box. It
can also be locked through a configuration option in the PEL Control Panel. When this option is enabled, the instrument
remains locked even when disconnected from the computer.

To return local control to the instrument, ensure that the “Lock out the Control button on the instrument front panel” option
in the PEL Control Panel is unchecked (see § 3.6). Then disconnect the instrument from the PEL Control Panel. If the instru­ment remains locked, check whether or not a recording is in progress. (The LED blinks twice every five seconds when
a recording is active.) If so, either stop the recording or wait until it completes (see § 5.2).

If some configuration screens are active, while others are inactive (or don’t appear at all), you may have the wrong hookup

type selected. Hookup settings can affect which configuration screens are available. In this case, enter Information
mode and ensure the appropriate hookup type is selected.

8.2.4 Recording Sessions Do Not Start

If you attempt to start a recording either by pressing or via the PEL Control Panel and the session does not start, check
whether or not a recording is already in progress on the instrument (the LED blinks twice per second). To start a new
recording, either wait for the in-progress recording to finish, or stop the recording.

Also check that the SD card is installed, operational, and has sufficient space to save the recording. If the LED glows
red, it is write-protected, not installed, or not recognized. If it blinks alternately red and green, it is full. If it blinks green once
per second, it does not have enough space for the recording you are attempting to start.

Another condition that could prevent a recording session from starting is if the start and/or end times and dates are config­ured incorrectly, such as a stop date/time that has already passed. If the instrument has sufficient memory for the recording
but it still will not start, check the recording’s start and stop times/dates to ensure they are configured properly.

See § 5.2 for information about configuring a recording session.

8.2.5 Recording Sessions End Prematurely

If a recording session terminates before its scheduled stop time, a likely cause is that the SD card memory has become
full. When this happens, the LED glows red. Download any data you want to save, then erase the contents of the SD
card through the PEL Control Panel (see § 8.1.1).

8.2.6 Cannot Connect to a Computer

If you cannot connect the computer via Wi-Fi or Bluetooth, ensure that the communication protocol through which you

are attempting to connect is enabled. Check the appropriate LED: for Wi-Fi, for Bluetooth. If it is OFF (indicating the
protocol is disabled) enable it as instructed in § 3.

Power & Energy Logger Model PEL 105

www.GlobalTestSupply.com

81

If the LED is blinking, the instrument is actively communicating with a computer. Only one Bluetooth connection at a
time is supported; so ensure no other Bluetooth connection is active before attempting to connect to the instrument via
Bluetooth.

If you are attempting to connect via USB or point-to-point Ethernet, ensure that the cable is securely connected to both
the instrument and the computer. If the connections are secure, close the PEL Control Panel, disconnect the cable, wait a
few seconds, then reconnect the cable. This resets the connection with the computer.

Also check the Communication settings in the PEL Control Panel, as explained in the PEL Control Panel Help system.

If you are attempting to connect via Bluetooth but you cannot connect the instrument via the PEL Control Panel – for exam­ple, the PEL 105 does not appear as available when you attempt to connect with it – the instrument may not be paired with
the computer. Different computers and operating systems have different processes for pairing Bluetooth devices; consult
the documentation that comes with your computer for instructions about how to do this.

8.2.7 Cannot Turn OFF the Instrument

The Power button is disabled if a recording is active or pending. In addition, you cannot turn OFF the instrument if it is
operating on external AC or phase power. Disconnect the power source, hold down until all the instrument’s LEDs light

up, then release the button to turn OFF the instrument.

APPENDIX A: THEORY OF OPERATION

The instrument calculates measurements in accordance with IEC 61557-12 and IEC 61010-4-30. The following is a graphic
representation of active and reactive power, in accordance with clauses 12 and 14 of IEC 60375.

Figure 36

In this diagram:

■ The current vector is fixed on the right-hand line.

■ The voltage vector V varies direction according to the phase angle ϕ.

■ The phase angle ϕ between voltage V and current I is considered mathematically positive (counter-clockwise).

A.1 Sampling

The sampling period is calculated every second, and varies according to the line frequency (50Hz, 60Hz, or 400Hz).

50Hz:

■ 42.5 to 57.5Hz (50Hz ±15%), sampling period is locked to the main frequency. There are 128 samples available
for each main cycle.

■ Outside 42.5 to 57.5Hz, sampling period is 128 x 50Hz.

60Hz:

■ 51 to 69Hz (60Hz ±15%), sampling period is locked to main frequency. 128 samples are available for each main
cycle.

■ Outside 51 to 69Hz, sampling period is 128 x 60Hz.

400Hz:

■ 340 to 460Hz (400Hz ±15%), sampling period is locked to main frequency. For each main cycle, 16 samples are
available.

■ Outside 340 to 460Hz, sampling period is 16 x 400Hz.

Note that DC is not a frequency parameter for sampling. A pure DC measured signal is considered to be outside the fre­quency ranges. In this case sampling frequency is 6.4kHz (50/400Hz) or 7.68kHz (60Hz). By default, sampling frequency is
locked on V1. If V1 is missing, the instrument attempts to lock sampling frequency V2, then V3, I1, I2, and I3.

83

A.1.1 Locking the Sampling Frequency

By default, the sampling frequency is locked to V1. If V1 is missing, the instrument attempts to lock to V2, then to V3, I1, I2,
and I3.

A.1.2 AC/DC

The PEL 105 makes AC and DC measurements for AC and DC distribution networks. AC or DC is selected by the user.

The AC + DC values are available via the DataView PEL Control Panel.

A.1.3 Neutral Current Measurement

Depending on the distribution network, if there is no current sensor on the IN terminal, the neutral current is calculated.

A.1.4 “200ms” Quantities

The instrument calculates the following quantities every 200ms based on measurements of 10 periods for 50Hz, 12 periods
for 60Hz, and 80 periods for 400Hz. The “200ms” quantities are used for:

■ Trends on the “1s” quantities

■ Aggregation of the values for the “1s” quantities (see § A.1.6).

All “200ms” quantities can be recorded on the SD card during the recording session.

A.1.5 “1s” Quantities (one second)

The instrument calculates the following quantities every 200ms based on measurements of 50 periods for 50Hz, 60 periods
for 60Hz, and 400 periods for 400Hz. The “1s” quantities are used for:

■ Real-time values

■ Trends

■ Aggregation of the values for the aggregated quantities (see § A.1.6).

■ Determination of the values and maximum/minimum for the values of the aggregated trends

All “1s” quantities can be recorded on the SD card during the recording session.

A.1.6 Aggregation

An aggregated quantity is a value calculated for a defined period. Aggregation periods always start on rounded hours/
minutes. The period is one of the following: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 minutes.

All aggregated quantities are saved on the SD card during the recording session. They can be displayed in the PEL Control
Panel.

A.1.7 Minimum and Maximum

The Min and Max are the minimum and maximum values observed during the aggregation period. They are recorded with
their dates and times. The Max of some aggregated values are displayed directly on the instrument.

Power & Energy Logger Model PEL 105

A.1.8 Energy Calculations

Energies are calculated every second. Total energy is the demand during the recording session. Partial energy can be
determined for one of the following integration periods: 1h, 1 day, 1 week, or 1 month. The partial energy index is available
only in real time. It is not recorded.

Note that total energies are available with the data of the recorded session.

A.2 Phase Sequence

Every second, the instrument determines the phase sequence. If the phase sequence does not meet the criteria listed in

the tables below, the red Phase Sequence LED blinks. In addition, the Phase Sequence icon appears on the LCD.

To ensure proper phase sequence, the current phase sequence, voltage phase sequence, and current vs voltage phase
sequence for that hookup must all be correct. Note that:

■ Phase sequence for voltage channels is only displayed when voltages are displayed on the LCD.

■ Phase sequence for current channels only is displayed when currents are displayed.

■ Phase sequence for voltage and current channels is displayed when the other screens are displayed.

■ Load or source is set by the PEL Control Panel.

■ In some hookups (such as DC) the phase sequence does not always apply.

The following tables list the measurement ranges that ensure correct current phase sequence, voltage phase sequence,
and current vs voltage phase sequence respectively.

APPENDIX B: MEASUREMENT QUANTITIES

The following table lists all quantities measured or calculated by the instrument, organized by hookup type. Circles indicate
that the quantity is measured for the hookup.

For example, the first quantity listed in the table is V1 (line 1 voltage). Circles in the 1P-2W and 1P-3W columns indicate
V1 is measured for single-phase 2-wire and single-phase 3-wire hookups. The absence of a circle in the 3P-3W∆b column
indicates V1 is not measured for 3-phase 3-wire ∆ balanced hookups.

GLOSSARY

Symbol/Term Definition

Phase angle. For example:

ϕ (I1, I2) is the phase angle between line 1 current and line 2 current.

ϕ 

A (Amps or
Amperes)

AC Alternating current.

CF

Cos ϕ Cosine of the phase shift of the fundamental voltage with respect to the fundamental current.

DC Direct current.

E

F (Frequency) Number of AC voltage or current cycles in one second, measured in Hertz (Hz).

Fundamental
frequency

Harmonics

Harmonic Order

Hz (Hertz)

I

ϕ (I1, V1) is the phase angle between line 1 current and line 1 voltage.
ϕ (U31, U23) is the phase angle between phase 3-to-phase 1 voltage and phase 2-to-phase

3 voltage.

ϕ (V1, V2) is the phase angle between line 1 voltage and line 2 voltage.

Unit of measure for current. For example:

AAC is AC current.

ADC is DC current.

Crest factor in current or voltage. This is the ratio of the Peak value of a signal to the RMS value
(Peak/RMS).

Energy. For example:

EP is active energy.

EP+ is consumed active energy.

EP- is generated active energy.

EQ is reactive energy.

ES is apparent energy.

ES+ is consumed apparent energy.

ES- is generated apparent energy.

Primary frequency of the AC electrical network, typically 50Hz, 60Hz, or 400Hz.

Voltages and currents at frequencies that are multiples of the fundamental frequency. Harmon­ics distort the fundamental waveform and can affect the performance of electrical equipment
and components.

Ratio of the frequency of the harmonic to the fundamental frequency; expressed as a whole
number. For example, in a 60Hz system the 1st harmonic order = 60Hz, 3rd order = 180Hz, 5th
order = 300Hz, and so on.

Unit of measurement for frequency, representing the number of cycles per second. For exam­ple, 60Hz equals 60 cycles per second.

Current. For example:

I1 is line 1 current.

IN is neutral current.

I-CF crest factor of current (Peak/RMS).

I-THD total harmonic distortion of current.

L Line (phase). For example, L1 is line 1 or phase 1.

MAX

MIN Minimum value.
