Turning the Instrument ON/OFF
The instrument can operate on three di󰀨erent sources of power:
■External power provided by plugging into an AC outlet with the AC adapter.
The instrument will always run on external AC power when plugged in, even
if phase voltage 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.
Turning the Instrument ON
■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.
Turning the Instrument OFF
The procedure for turning OFF the instrument depends upon the power source.
■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.

Wi-Fi Direct Connection
Before you can connect through the PEL Control Panel, you must create a
Wi-Fi connection between the computer and instrument in Microsoft Windows. A
direct Wi-Fi connection requires the instrument’s SSID number and (if required)
password, which you can dene by connecting the instrument via USB cable,
opening the Control Panel, and displaying the Congure dialog box, as instructed
by the Control Panel Help. The Congure dialog box includes elds for setting
Wi-Fi connection options.

For this type of connection, the instrument must be connected to a network
accessible to the computer. The network connection can be either via LAN or
Wi-Fi router. Consult your network administrator if you need assistance with this.
When this connection is established, open the PEL Control Panel and do the
following:
1. In the menu bar at the top of the screen, select Instrument.
2. In the drop-down menu that appears, click the option Add an Instrument.
3. Select Ethernet (LAN or Wi-Fi) as the connection type, and complete the Add
and Instrument dialog. If you need assistance, press the Help button.

14 Power & Energy Logger Model PEL 105 - Quick Start Guide
Network via IRD Server
An IRD server allows you to connect your computer to instruments on di󰀨erent
networks. You must rst connect the instrument to a network that can access
the internet. Consult your network administrator if you need assistance with this.
When this connection is established, open the PEL Control Panel and do the
following:
1. In the menu bar at the top of the screen, select Instrument.
2. In the drop-down menu that appears, click the option Add an Instrument.
3. Select IRD server as the connection type, and complete the Add and
Instrument dialog. If you need assistance, press the Help button.

connected with the computer. Click Close to exit the screen.
5. Open the PEL Control Panel. In the menu bar at the top of the screen, select
Instrument.
6. In the drop-down menu that appears, click the option Add an Instrument. This
opens the Add an Instrument Wizard dialog box.
7. Select Bluetooth as the connection type, and complete the Add and
Instrument dialog. If you need assistance, press the Help button.
Installing the SD-Card
Data recording sessions are stored in the included 8 GB SD card, which also
accepts FAT32 SDHC cards up to 32 GB capacity. If the SD card is unformatted,
you will need to format it before use. Formatting can be done through a Microsoft
Windows command or through the DataView®PEL Control Panel.
To install the SD card:
1. Locate the card slot on the front panel.
2. Ensure that the write-protect sliding tab on the card is in the “unlock” position
(towards the metal contacts).
3. Insert the SD card into the slot, with the metal contacts facing up (towards the
top of the instrument).
4. Press the SD card into the slot until it clicks in place.
5. Press the attached cap into the card slot to ensure water resistance.
6. If the SD Card is not formatted, the LED glows red. To format the
installed card, open the PEL Control Panel. Click Instrument in the menu bar
and select Congure. Then click Format SD-Card in the General tab of the
Congure Instrument dialog box, and click Yes to conrm.
7. When the card is installed and ready for use, the LED glows steady
green. To remove a card, press down on it until the card unclicks. It will pop
up, allowing you to pull it from the slot.

Power & Energy Logger Model PEL 105 - Quick Start Guide 15
Setting the Instrument Clock
Before using the instrument, you should ensure the instrument clock is set to
the correct time zone. By default the PEL 105 is set to Universal (UTC) time. To
change this to another time zone, do the following:
1. Open the PEL Control Panel and connect to the instrument, as instructed in
the preceding section “Connecting to the Computer.”
2. Select Instrument in the menu bar, and select Congure. This opens the
Congure dialog box.
3. In the General tab, click the Set Clock button to display the Date/Time dialog
box.
4. You can synchronize the instrument’s clock with the computer’s clock, or use
the Date and Time elds to select another date and time. You can click the
Set Time Zone eld to select a time zone adjustment. This denes the number
of hours by which the instrument’s local time di󰀨ers from UTC time. For
example, if you set the adjustment to -4, the PEL 105 will display its local time
as 4 hours “behind” UTC (e.g. when local time is 12:00 PM, UTC is 4:00 PM)
NOTE: This adjustment also applies when you select Synchronize
with PC Clock.
When you do this:
■The Control Panel reads your computer’s time and time zone information.
■The time is converted to UTC.
■The instrument’s UTC time is set to the computer’s UTC time.
■The time zone adjustment is applied to the UTC time to derive the
instrument’s local time.
5. Complete the Date/Time dialog box and click OK. Then click OK in the
Congure dialog box to set the clock on the instrument.

16 Power & Energy Logger Model PEL 105 - Quick Start Guide
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 Conguration mode). The instrument
cannot begin a recording when it is locked. The instrument is locked when:
■Being congured via the PEL Control Panel.
■Disabled through an option in the PEL Control Panel.
■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 e󰀨ect, 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.
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.
■If the LED blinks orange, 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 ve 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
the PEL Control Panel, open the Help system, and follow the instructions for
downloading and viewing recordings.

Distribution Systems and Hook-ups
The following hookup diagrams and connection instructions are for distribution
systems supported by the PEL 105. The instrument must be appropriately
congured for the hookup type. Most conguration is performed through the PEL
Control Panel, as described in the Help. Some conguration can also be done
via the instrument’s front panel, as described in the user manual. Ensure that the
current arrow on the sensor is directed towards the load. This ensures proper
phase angle for power measurements and other phase-sensitive measurements.
