7.5 Load cell calibration

Two types of calibrations are available for the TrueFeed, depending on the selection made in

CONFIGURATIONS:

1. Automatic - The advantage of automatic calibration over manual calibration is that the automatic

calibration is self-calibrating and the probability of failures will be reduced. Also, the accuracy is higher

with changes of output because a complete material curve will be produced.

2. Manual - Running in RPM mode (external scale is required)

When using a TrueFeed for the first time, a load cell calibration must be performed:

• The unit must be mounted horizontally (water leveled)

• Avoid vibrations during the load cell calibration. This will effect the calibration.

• Do not touch the unit during load cell calibration.

• When using an optional slide frame the unit must be slid in against the throat adaptor and secured.

• Be sure that the load cell is connected to the control

• Navigate to the LOAD CELL menu

• In this menu it is possible to calibrate the load cell of TrueFeed

(a 1.1 lb {500 g}. calibration weight is required)

• Select “YES” to start the load cell calibration

[***] = Progress

• After a few minutes the following screen appears:

Place the calibration weight (1.1 lb {500 g}) on the hopper

and press the “START” button.

• After approximately one (1) minute the load cell calibration will be complete, press the “MENU” button to

continue.

• To check if the load cell calibration was correct, navigate to the WEIGHT CHECK menu.
