If the values are correct press
to accept or
to reject the results
Before proceeding with other calibration procedures or normal operation verify that pulses are
turned back on to the controller.
Zeroing Procedure
The purpose of the Zeroing Procedure is to zero the load value when the belt is empty.
This procedure will measure the average load over the length and adjust the zero load
value accordingly. The Zeroing Procedure is accomplished by the controller recording
weight readings while the feeder is running empty. For a correct Zero Load value to be computed
the belt should be empty during the test. The controller will record load readings for a certain
amount of belt revolutions. The number of belt revolutions for the test is determined by the
parameter “# Proc Revs” (page 28). After the correct number of belt revolutions are reached, the
controller will display a difference value computed for the change in the zero load value. You will
then have the option of accepting or rejecting the new zero load value.
If you do not wish to run the Zeroing Procedure, press the
button to return to the
Calibration Menu. However, if you are ready to begin the Zeroing Procedure press
. The
display will show the percent of the test completed.
