 Use caution when working in potentially hazardous locations such as an elevated
location on a ladder or roof top, especially if work is occurring in proximity to a
lightning storm. Also use caution if external communication cables are run at
length in parallel to electrical power installation cables. These types of
installations can expose communication cables to coupled electrical transients
that could be accessible on exposed conductive parts of the equipment during
operation. While in general these transients are not expected to be an electric
shock hazard, startled reaction from these transients could lead to a secondary
hazard such as loss of balance and lead to a fall or other injury. To reduce risk of
exposure, limit contact to accessible conductive parts of I/O terminals during
operation.
Cable Tests
In a twisted pair cable test, the Product performs a series of radio frequency (RF) tests to
determine the transmission parameters of the cable. The parameters are compared to the test
limits specified by IEEE 802.3 for Ethernet. Unlike transmission testers that pass bits across
the cable, the Product evaluates the physical qualities of the cable.
 Measures length up to 304.8 m (1000 feet)
 Delay skew between pairs
 Transmission parameters used to qualify the cable:
 Cable qualification to IEEE 802.3 standards:
 Uses wire maps to show:
 Insertion loss
