Belt Speed Compensation
To achieve optimum accuracy in the rate computation, the belt speed displayed must equal that
of the actual belt speed. As the speeds are likely to differ, a belt speed compensation should be
performed.
Run the conveyor with the belt empty.
View the belt speed.

V
0.60
For example: current speed of 0.6 m/s
Stop the conveyor and measure a length of the belt; marking the forward end (start time) and the
back end (stop time). Use the belt scale as the stationary reference.
Run the belt and measure the time for the belt length to pass over the scale.
speed = (belt length / time) m/s or ft/min.
Refer to the Start Up (Page 47) section for instructions on parameter selection and changing
values.
