TrueBlend™ Operation
Edition: February 2008 63
7.7.2.2 Calibrating material throughput
The material throughput calibration is automatically run on startup and is self-
optimizing during production.
The respective dispensing valve(s) are run with reduced batch weight(s) at
startup. The optimum working point is set after several batches. A high mix-
ing precision is quickly reached with a small quantity of material. Finally it
is switched to the preset batch weight.
NOTE
Conair recommends performing a manual calibration at start-up or material
change with a dramatic change in the bulk density of the material being
blended. This allows the blender to reach its optimal working point more
quickly.
