Recommended Working Load for Rope
The recommended working load is determined by taking the average tensile strength of new
rope under laboratory conditions, and dividing by a factor to determine the maximum load that
should be applied to the rope. The factor varies with type of fiber and construction. This factor
usually is sufficient to assure you of a comfortable safety margin, however, there are exceptions.
Synthetic fibers are susceptible to degradation and damage in many ways that are controllable by
the manufacturer. Therefore, it is imperative that the rope be inspected before use, and if it shows
signs of excessive wear it should be replaced.

Calibration
!NOTE: The Condux Running Line Tensiometer, as with many measuring devices,
must be calibrated regularly to ensure its accuracy.
We recommend both the Mechanical Sensing Unit and the Electronic Control Box be returned to
Condux at least once a year for calibration.
Call Condux Customer Service for a Return Material Authorization number. Follow the
instructions on the RMA and ship both the Mechanical Sensing Unit and the Electronic
Control Box, freight prepaid, to:
Condux International, Inc.
145 Kingswood Drive
Mankato, MN 56001 USA
The running line tensiometer will be calibrated and shipped back within 48 hours of receipt.
There may be a nominal charge for the recalibration of your running line tensiometer.
