Note:
This method may also be used to set the clamping force of the rollers on the cable. Initially,
the clamp arm lever should be set so that the rollers press very lightly onto the cable.
Carry out the test outlined above (drive the cable into the closed end of a sample tube). The
rollers will slip. Repeat this procedure, each time increasing slightly, the pressure the rollers
apply to the cable. Eventually the rollers will stop turning because the torque limit has been
reached. It is worth noting at this stage that this approach may result in a great deal of force
being applied to the cable. More than the cable can withstand without sustaining damage,
sometimes it may be that the cable may be protected from buckling by a combination of
torque control setting and slip. The main purpose of the exercise is to install the cable as far
as possible without causing damage to the outer sheath, in some circumstances a compro-
mise may be found that uses a degree of torque control and slip.
