Stress Test Effectiveness
The stress test identifies capacitive imbalances
(i.e., unequal conductor lengths) and DC problems
(i.e., crosses and grounds) anywhere along the length
of a dry or idle-working pair.
The STRESS measurement on the Sidekick
®
Plus test
set is more sensitive to pair imbalance problems than
noise metallic and ordinary longitudinal balance tests.
Series faults that cause static noise, however, need
305 m (1000 ft) of pair beyond the fault to cause a bad
stress reading.
The closer the technician is to a fault, the higher the
stress reading will be.
Note: The STRESS measurement does not identify
shorts because a shorted pair is balanced and pro-
duces good stressed noise readings. Use the LEAKAGE
measurement to identify shorts.
STRESS Measurement
To perform the STRESS measurement:
1. Connect the black lead to tip, the red lead to ring,
and the green lead to ground.
2. Move the rotary knob to the STRESS position.
To exit the STRESS function, move the rotary knob to
any other position.
The following is a guideline for pair performance:
• Scale: 0 to 82 dBrnC
• Acceptable: 20 dBrnC and lower
• Marginal: 20 to 30 dBrnC
• Unacceptable: above 30 dBrnC
Specifications for this measurement are as follows:
• Range: 0 to 82 dBrnC
• Resolution: 0.1 dBrnC
• Accuracy: ±5 dBrnC overall;
±2 dBrnC from 10 to 50 dBrnC
• Longitudinal excitation: +90 dBrnC; ±6 dBrnC
