  • Page 14: Theory Of Operation

    Theory of operation The method by which the LI-3000C measures area is best understood by examining the technique for manual area measurement. Manual area measurement requires tracing the outline of the sample on graph paper and methodically counting the squares where the sample covers fifty percent or more of the area of an individual grid cell.

  • Page 15: Instrument Calibration

    Section 1. General information sequentially pulsed. The scanning process begins only when the length encoding cord is pulled. Since 1 mm of cord travel is equivalent to the side of a grid cell, it is apparent that the length encoding cord must be pulled perpendicular to the row of 128 LEDs. When the LED light is blocked by a sample, the unit area (1 mm ) is accumulated on the display.

  • Page 17: Section 2. Preparations

    Operational check The following procedure can be used to connect the scanning head to the readout console and verify that the LI-3000C is working properly. Connect the scanning head to the readout console while the ON/OFF switch is OFF. Mate the cable connector with the connector on the back panel of the readout console, and then push in and turn the collar clockwise until it locks into place.

  • Page 18: Recharging The Battery

    Clear any logged area data by pressing the white reset button located on the scanning head handle. Recharging the battery The LI-3000C uses a sealed lead acid battery. This battery is rechargeable, and gives about 12 hours of use. The symbol appears on the display (as shown below) when approximately 1 hour of battery life remains.

    In many cases the LI-3050C Transparent Belt Conveyer Accessory will be the method of choice for measuring small objects and detached leaves. The com- bination of the LI-3050C and LI-3000C provides greater accuracy (±1%) than the LI-3000C alone (±2%).
