3. If the Logger is able to determine a better phase map or polarity,
click on Auto Correct to apply the new settings.
Auto Correct is not available if the algorithm is not able to
detect a better phase map or when no errors are detected.
It is impossible to detect all incorrect hook-ups automatically.
You must verify the suggested modifications carefully before
you apply the digital correction. Applications with single-
phase energy generation can deliver the wrong results when
you apply the Auto Correct feature.
The algorithm creates a sequence with a clockwise phase
rotation.

Instrument Setup

This setup section is about the requirements to perform a power or
power quality study. The setup will verify that the details of the study
are correct and that useful, actionable data is collected for reports.

Instrument Name

You can assign a name to the Logger. This name is attached to the
measurement files when you review these files in Energy Analyze
Plus software. The default name is FLUKE174x<serial number>, for
example: FLUKE1748<12345678>.
User credentials. This allows to configure custom user credentials
to permit access to the device configuration. The factory defaults are:
User name: admin
Password: admin
If you do not know the credentials, download recorded data from the
Logger and perform a factory reset with the Start/Stop button during
power-on. See Reset to Factory Defaults for more information.

Time Synchronization

Set one of the available clock sources:
Manual. Manually synchronize the Logger clock with the clock of the
remote client. In Energy Analyze, it is also called "PC Time".
The clock meets the requirements defined in IEC 61000-4-30 Class A
to allow a maximum deviation of 1 s/day when the synchronization is
unavailable.
Internet Time. The Logger will contact a time server on the Internet
(NTP) and keeps the real-time clock synchronized during long logging
sessions. This setting requires a connection to the Internet. See
Network configuration for details. Time stamps of resulting logging
data will be more accurate than using the manual time
synchronization mode also over longer periods, but may not comply
with IEC 61000-4-30 Class A requirements.
GPS. Set this option when using the GPS receiver FLUKE-174X
GPS-REC. Refer also to GPS Time Synchronization Input for details.
For IEC 61000-4-30 Class A measurements Fluke recommends that
you use this setting for the best real time accuracy of less than
±1 cycle.

Ethernet Configuration

Use the Ethernet port to configure the Logger and download
measurement data with Energy Analyze Plus software. The Ethernet
port is also used for the Network Time Protocol (NTP) to periodically
synchronize the real-time clock when Internet Time is configured. You
can either enter a specific address or indicate that the address is
found automatically over the network.
An automatic address is assigned by a DHCP server if one is
available on the network. Otherwise, contact the networking
or IT department to get access to fixed IP address.
