Calibrating the belt speed
Aftercalling DISPENSER PARA > Encoder Diameter the following is displayed:
• x.x = diameter of measuring wheel
• yy.y = belt speed according to current measurement
• var = indicates
variable belt speed
If the actual belt speed is known, the measured speed can be synchronised with it as
follows:
 Increase or decrease the diameter of the measuring wheel until the belt speed dis-
played matches the actual speed.

The file „APSF.xls“ contains a calculation sheet for the purpose of calculating or
checking encoder data [34].
Using the calculation
sheet

Open the file „APSF.xls“ [34].
Requires Microsoft Excel or a compatible spread sheet program.
The file is contained on the labeller documentation CD in the folder „/utilities“.

Enter the parameters of the configuration into the input fields [34A].
