4) Measuring tension
(1) Lower indicator arm (1) into the scale.
Apply tester to belt at a point
midway between two pulleys so
that edge of contact surface (2) is
flush with the V- belt.
Slowly depress pad (3) until the
spring can be heard to disengage.
This will cause the indicator to
move upwards.
If pressure is maintained after the
spring has disengaged a false
reading will be obtained!
(2) Reading of tension
Read of the tensioning force of the
belt at the point where the top
surface of the indicator arm (1)
intersects with the scale.
Before taking readings make ensure
that the indicator arm remains in its
position.
