  • Page 6: Scale Annunciators

    Fig. 1: Model 4300 Front Panel Layout The operational controls for the Model 4300 consist of the ZERO, PRINT, UNITS, OVER and UNDER buttons. A six digit LED display is used to display weight and operator messages during scale operation. Three lights, above the LED display indicate checkweighing status.

  • Page 7: Power Up

    Motion indicator. This symbol represents motion or instability of the weight. The annunciator will illuminate when motion is sensed on the platform. Changes in weight, vibration or air currents can cause the scale to go into motion. Under illuminates to indicate weight is below the Under target and above the Low target or flashes if below the Low target.

  • Page 8: Over

    There are many parameters that customize the control of manual and automatic transmission of data. Data can be transmitted via standard RS232, Ethernet, WiFi, Bluetooth or USB. Contact Doran Tech Support at tech@doranscales.com for support. OVER OVER allows entry of the upper checkweighing limits. It is also used to increment a checkweighing value that is being modified.

  • Page 9: Battery Operation

    Battery Operation The 4300 can be optionally configured with a self-contained Rechargeable Sealed Lead-Acid battery and charging circuit, both internal. The scale is designed to run continuously for up to 60 hours with a single 350 ohm load cell. To maximize battery life, leave the auto-off timer enabled which will automatically power down the scale after a period of non-use.
