Introduction

The 3540 FC 3 Phase Power Monitor (the Monitor or
Product) is a compact device to monitor 3 phase systems
and stream data to the Fluke Connect® Cloud. The
measurement data from the Fluke Connect Cloud is
available on any connected device using the Fluke
Connect mobile app or web interface. Graphs are available
to show the trends and fluctuations of the measurements
during the monitoring period. Optional alarm settings can
notify users immediately when measurement values are
outside specified thresholds.

The Monitor includes a mode to log measurements when
no connection to the Fluke Connect Cloud is available.
You can sync Logged data with the Fluke Connect mobile
app to the Fluke Connect Cloud.

The Monitor makes these measurements:

 Voltage (V)
 Current (A)
 Frequency (Hz)
 Power (W)
 Apparent Power (VA)
 Non-active Power (var)
 Power Factor (-)
 Total Harmonic Distortion Voltage (%)
 Total Harmonic Distortion Current (%)
 Harmonic Content Current (A)
 Harmonic Content Voltage (V)

The total number of measurements depends on the
selected topology (wiring configurations), like Wye, Delta,
or Split Phase.

iFlex Current Probe

The iFlex Current Probe works on the Rogowski coil (R­coil) principle that is a toroid of wire used to measure an
alternating current through a wire encircled by the toroid.

The R-coil has many advantages over other types of
current transformers:

• It is not a closed loop. The second terminal is passed

back through the center of the toroid core (commonly a
plastic or rubber tube) and connected along the first
terminal. This allows the coil to be open-ended,
flexible, and able to be wrapped around a live
conductor without disturbing it.

• It has an air core rather than an iron core. It has a low

inductance and can respond to fast-changing currents.

• Because it has no iron core to saturate, it is highly

linear even when subjected to large currents, such as
those used in electric power transmission or pulsed­power applications.

A correctly formed R-coil, with equally spaced windings, is
largely immune to electromagnetic interference.

Use the color clips for easy identification of the current
probes. Apply the clips that are appropriate for your local
wiring codes on both ends of the current probe cable. See
Figure 3.

Kensington Lock

A Kensington Security Slot (also called a K-Slot or
Kensington lock) is part of a built-in anti-theft system. It is
a small, metal-reinforced, oval hole found on the right side
of the Monitor (see item 6 in Table 3). It is used for
attaching a lock-and-cable apparatus. The lock is secured
in place with a key or combination lock attached to a
plastic-cover metal cable. The end of the cable has a small
loop that allows the cable to be looped around a
permanent object, such as a cabinet door, to secure it in
place. This lock is available from most electronics and
computer suppliers.

Storage

When not in use, keep the Monitor in a protected storage
space. If the Monitor is stored for an extended period of
time or is not in use for a long time, you must charge the
battery at least once every six months.

Tilt Stand

The power supply includes a tilt stand. When used, the tilt
stand positions the display at a good angle for use on a
tabletop surface. To use, attach the power supply to the
Monitor and open the tilt stand.

Power Supply

The Monitor includes a power supply, see Figure 4.
Connect the power supply externally in locations where the
Monitor with the power supply attached is too big to fit in a
cabinet between the door and panel.

When the power supply is connected to the Monitor and
line power, it:

• converts line power to dc power and is used directly by

the Monitor

• automatically turns on the Monitor and continuously

powers the Monitor from the external source (after
initial power on, the power button turns on and turns
off the Monitor)

• recharges the battery

XW Warning

To prevent possible electrical shock, fire, or
personal injury, do not use the power supply if
the mains power cable/measurement line slide­cover is missing.
