Using Control Knob 
The control knob is located to the right of the softkeys. The control knob accesses the 
on-screen switches and manually inputs data. The available on-screen switches are 
dependent upon the setup configuration of the balancer. 
Pushing in on the control knob cycles through the available on-screen switches on the 
current primary screen. Rotating the control knob clockwise or counter-clockwise 
changes the setting for the selected on-screen switch. 
For example, in the “Balance” primary screen, pushing in on the control knob will cycle 
through the grams to ounces, the static and dynamic, and the SmartWeight/Standard 
balance screen switches. After selecting an on-screen switch, the setting may be 
selected by rotating the control knob. The “selected” switch is the one showing the 
hand.
