The most common Probe Mounting Fixture
for use with the BriteSpot™ system is based on
industry standard ring-style cable termination
lugs. These lugs have proven to be reliable,
easy to install, and virtually maintenance
free. In addition, if installed at locations
with existing hardware, no modifications to
hardware lengths or specifications are needed.
The fiber probe has a special feature, called the
Probe-Lock which secures the Probe to the lug
without crimping, allowing lugs to be installed
first, then the attachment of the probe.

1. Select the proper lug of the application
based on the existing hardware (if present)
or planned hardware. Any #6 AWG
Tyco/Amp Solistrand™ ring-style lug should
be compatible, however not all have been
tested. If purchased in kit form, 1/2 inch
lugs have been included. Other sizes are
also available as seen in Figure 10 . When
selecting the lug for a given location,
ensure that the lug with the tightest fit
around the hardware is selected – this aids
in proper thermal conduction and will
result in more accurate readings.

2. To make probe installation easier,
consideration must first be given to
the rotational orientation of the lug
before it is mounted. When the probe is
eventually installed, the fiber will need
to have a relatively unobstructed path
to be inserted into the lug. For example,
in some situations protective boots are
placed over bolted connections, posing
an inconvenience when routing the fiber.
Align the fixture to allow the fiber to be
threaded through existing seams in the
dielectric boot. The lug must also be placed
such that the Probe-Lock is accessible to an
Allen Key for tightening.
3. Mount the lug so that it is directly
contacting the surface to be measured.
Washers should NOT be placed between
the lug and the surface to be measured;
instead they should be placed on the other
side of the lug, as shown in Figure 11 .
Figure 12 shows the proper installation
when Belleville washers are used.
Absolutely no greases and / or pastes
should be used between the lug and
the surface it is contacting. Ensure the
orientation of the lug is such that the probe
and fibre run parallel to the bus.
