Note
Set the current range to Auto when you are not sure about
the maximum current during the logging session. A specific
application can require you to set the current range to a fixed
range rather than Auto. This can occur because the Auto
range is not gapless and may lose too much information in
the case of a highly fluctuating current.
Current Ratio
Configure a ratio factor for the current sensors when a current
transducer (CT) is used to measure the much higher level on the
primary side at a substation or step-down transformer that has a built-
in metering current transformer.
The current ratio can be used to increase the sensitivity of the iFlex
sensor. Wrap the iFlex sensor around the primary conductor, for
example 2X, and enter a ratio factor of 1:2 to get correct readings. The
default value is 1:1.
Auxiliary Input
The Logger supports up to two additional measurement channels with
either the wired AUX input or wireless radio signals from Fluke
Connect sensors.
Wireless Connection to Fluke Connect Modules
The Logger supports wireless radio communication with Fluke
3000-series modules to remotely monitor equipment. See Figure 6.
Wireless communication requires that the USB-1 FC WiFi-BLE
adapter is installed. See WiFi and WiFi/BLE-to-USB Adapter on
page 6 for more information.
To set up a module:
1. Turn on the module.
2. Push  on the module to turn on the radio. The display shows
.
3. On the Logger, select AUX 1 or AUX 2. Active FC sensors within
a 10 m range show in the selection list on the Logger. Highlight
the FC module and push
. The Logger assigns an ID number
to the module.
4. Verify on the module:
• ID number shows on the module
•  flashes to confirm the connection
Note
FC modules that are connected to another device are not
available and do not show in the selection list.
5. Verify that the Measurement Configuration screen shows the ID
number and module type in the AUX field.
If the module moves out of range, the ID number does not
show in the Measurement Configuration screen to indicate that
the connection is broken. The connection is re-established when
the module moves back into range.
6. On the Logger, go to the Meter screen to view the measurements
from the connected module.
Note
You cannot change the measurement parameter or unit on
the module during a logging session.
