Page 7: Operations
CW250, Users Rev M, April 2018 Operations CW250 Scale Display Description The display is a Liquid Crystal Display unit (shown below) providing one line of 5 1/2 digits. The screen displays the weights read from the pad. Information displayed includes indicators for "lb" and "kg" unit of measure, a segment bar to show battery charge level, error conditions, and set-point indicators that show when set-point thresholds are reached. -
Page 8: Control Functions
If a problem is detected during self-test, the screen will display an error message. To turn the scale off, press the On/Off key. The CW250 retains the setup information and calibration in a special memory device (non-volatile memory) that is not affected by power loss or battery condition. - Page 9 CW250, Users Rev M, April 2018 ZERO The ZERO key will reset the weight on a scale to read zero (either lb or kg unit of measure). If the ZERO key is pressed when a pad holds weight, the current weight becomes the zero condition for the pad.

Page 10: Totalizing Setup
Rev M, April 2018 Totalizing Setup The CW250 scale must be setup correctly in order to communicate with other scales in the system. If the system is not setup correctly, an "error icon" and message “ “will be displayed when attempting to view the total weight. - Page 11 CW250, Users Rev M, April 2018 ACCUMULATE NOTE: The scale will not accumulate when the weight is negative, zero, or if the weight is in motion. The protections are added to ensure only valid readings are accumulated into the total. An error message "." will be displayed when any of the three conditions are present.
