Page 11: Scale Overview
SCALE OVERVIEW SYSTEM OVERVIEW The LP600 Low-Profile Scale is comprised of the active weighing platform and control panel. The Control Panel, located at the front of the scale houses the system electronics, LCD display screen and a solar panel for powering the scale.
Page 12: Display Description
7005056 Rev J, August 2023 SCALE OVERVIEW DISPLAY DESCRIPTION The LP600 control panel uses a Liquid Crystal Display (LCD) unit (shown below) providing one line of 5 1/2 digits. The screen displays the weight read from the scale. Other information displayed...
Page 13: Control Panel Functions
To turn the scale off, press the ON/OFF button. The LP600 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 14: Scale Operation
LOCAL / TOTAL The LOCAL/TOTAL function is used when the LP600 is cabled directly to the scales and not connected to a central CPU or indicator. The Local Weight refers to the weight on a specific scale.
Page 15: Zero
The ZERO function can also be used when a non-zero value is displayed with no weight on the scale. ATTENTION: The LP600 scale has an integrated Auto Zero Tracking (AZT) feature that corrects for slight zero changes that may occur during normal operation.
