Sidekick

Plus Test Set
Measuring Cable Length
The LENGTH selection measures the distance to an
open, mutual capacitance as well as the conductor to
ground capacitance of the pair.
Note: This Sidekick
®
Plus test set can subtract the test
lead length from the LENGTH measurement. Refer to
“Cord Calibration’” in the “Tools Menu” section.
To measure cable length, perform the following steps:
1. Connect the test leads: black to tip, red to ring, and
green to ground.
2. Move the rotary knob to the LENGTH position.
A single pair measurement in feet (or meters) appears
on the LCD screen.
To change the single pair measured or make another
choice, use the following function keys:
•
F1 T-G
displays tip-to-ground; “T-G” now in the
upper left corner and “T-G” button is highlighted.
To return to tip-to-ring, press
F1
again.
•
F2 R-G
displays ring-to-ground; “R-G” now in the
upper left corner and “R-G” button is highlighted.
To return to tip-to-ring, press
F2
again.
•
F3 3-Lead
accesses the 3-lead screen.
•
F4 Setup
shows the measurement configuration. The
measurement unit, mutual capacitance, and ground
capacitance is set on this page. Press the
O
(
Back)
key to return to the measurement.
To exit the LENGTH function, move the rotary knob to
any other position.
Changing Capacitance per Distance
Use the up (
2
) and down (
8
) keys to adjust capacitance
per unit length displayed in the upper right of the
screen. Adjust the capacitance per distance value to
match a known length of cable or a known capacitance
per distance for a given cable.
Note that there are two capacitance per distance
values. One is for the T-G and R-G capacitance, while
the other is for T-R.
