1
Raise centre pulley by turning handle anti-clockwise until the instrument can be placed on the rope.
2
Lower centre pulley, turning handle clockwise, until all three pulleys are in contact with the rope. Ensure the rope is centrally located in the pulley grooves, deflection reads zero.
3
Continue turning handwheel until deflection (factor) gauge needle reaches required factor (typically 10 and /or deflection 3 degrees)
4
Read the value off the load gauge
5
The rope tension is then calculated from: Tension = Load gauge reading x Factor gauge reading
6
DO NOT allow either gauge needle to go beyond the scale end as it will damage the instrument
7
To remove the instrument, turn the handle anti-clockwise until both gauges read zero and the pulleys are free of the rope. The instrument can then be removed.
8
On open lay ropes ensure the deflection pad is in contact with a crest before taking readings.
 
Notes:  
a)
For use as a comparator only. Suitable for ropes from 6-26 mm diameter
b)
Model 'A' centre distance between pulleys = 305 mm
c)
Before deflecting the rope, the deflection gauge should read zero with both outer pulleys in contact with the ropes
d)
The amount of deflection should always be as large a spossible to reduce the factor
e)
Normal accuracy is ±5% when used on flexible wire ropes. The accuracy can be improved by calibrating the instrument using a similar rope sample in a tensile testing arrangement. We recommend this is carried out.
