  • Page 7: Section 1. General Information

    General Information 1.1 Instrument Function The LI-3100C Area Meter is designed for biological, industrial, and other applications requiring rapid, precise area (length or width) measurements. Samples are placed between the guides on the lower transparent belt and allowed to pass through the instrument. As items...

  • Page 8: Operational Features

    General Information 1.2 Operational Features The LI-3100C features interchangeable 1.0 mm and 0.1 mm resolution capability that is furnished with a single 28 mm camera lens. A 25 cm wide sample guide is provided for both 1.0 mm 0.1 mm resolution configurations.

  • Page 9: Section 2. Pre-Operation

    Pre-operation The following procedures must be performed before using the LI-3100C for the first time: Tighten the transparent belts Install the 15 watt fluorescent tube Install the camera lens Set the voltage selector at the proper position and check to see if the correct fuse is installed Each of these procedures is discussed below.

    Preoperation Procedure 2.5 Voltage Selector Operation and Characteristics The voltage selector is located in the power connector module (Figure 1). The selector is inspected for proper voltage by sliding the clear plastic window to a position over the power connector. The visible number on the small printed circuit board located under the fuse indicates the selected voltage as follows: either 100 or 120 V for 105-126 VAC operation...

  • Page 14: Section 3. Operation

    Operation 3.1 Instrument Activation After reading and performing the procedures in Section 2, the following steps should be taken to activate the instrument: Connect the supplied power cord to the power input connector at the rear of the instrument. A grounded three prong wall connector is required for electrical service.

  • Page 15: Belt Tension And Tracking Adjustment

    Operation 3.3 Belt Tension and Tracking Adjustment Belt tracking is adjusted by moving the sliding pulley bearing blocks (Figures 1 and 2). The belts likely will not maintain alignment without some adjustment. If a belt progresses toward one end of a pulley, then tighten that side of the belt.

    Operation opposite effect. In addition, incorrect calibration resulted in larger errors with these samples. The LI-3100C now uses the entire 25 cm measurement width for high resolution (0.1 mm ) mode, so it is important to compensate for the above-mentioned edge effect for the calibration procedure. While...

  • Page 20: Section 4. Changing Measurement Resolution

    Changing Measurement Resolution 4.1 Choosing Measurement Resolution The LI-3100C utilizes the full measurement width at all times, for both 0.1 and 1.0 mm resolution. The 0.1 mm resolution may be preferable , since it provides the best accuracy, particularly with small or complex shaped objects to 0.5 mm in width.

    Maintenance 5.6 Cleaning the Motor and Belt Drive System The motor and belt drive system requires no routine service or lubrication. If excessive debris becomes embedded into the belt, it can be removed with a small stiff brush.

  • Page 29: Section 6. Removing The Upper Belt Assembly

    Removing the Upper Belt Assembly 6.1 Purpose Some sampling requirements are better served by single belt operation. Under some conditions, the upper belt pressure may damage samples, or the upper belt rocking idler may cause undesirable mechanical pressure. Removing the upper belt pulley, drive pulley, and rocking idler will provide a more obstruction-free path through the sensitive area.

Be certain that all pulleys and idlers remain in place, resting on the support brackets (Figure 8). This is accomplished by repeatedly pressing the pulleys and idlers back into their rear plate bearings.
