CREEN
At the top of the screen you can see colors corresponding to the test leads. Ensure that the connection to
the faulty pair corresponds to these colors.
For single section testing (i.e. the length of circuit under test is the same gauge) the user needs to enter /
verify information about Cable Type, Resistance per length, Distance, Temperature and whether or not there
are load coils on the line.
CABLE TYPE:
The CABLE TYPE setting is used to select the appropriate cable type or more
appropriately the appropriate diameter. The available options for Imperial
Measurement Units are 19, 22, 24, and 26 AWG. For METRIC Measurement Units,
the options are 0.4 mm PE, 0.5 mm PE, 0.6 mm PE , and 0.8 mm PE. Note: AWG =
American Wire Gauge.
RESISTENCE
PER LENGTH
Allows the user to specify the cable’s resistance constant. See Appendix B for more
information on loop characteristics.
NOTE: When the Cable Type or Temperature changes, this value will automatically
change to reflect a new cable type or a lower or higher temperature. The initial setting
is based on nominal room temperature (68°F or 20°C).
