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.

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.
