    5.2.4 Date Entry (A13) If your indicator was ordered with the Time and Date option, it will keep track of the current date for you, which can then be printed on the print ticket. Use this procedure to set the current date, which must be set in mm/dd/yy format. For example, for January 7, 1998, you would enter 010798.

  • Page 27: Chapter 6: Calibration

    CHAPTER 6: CALIBRATION CALIBRATION OVERVIEW The indicator is calibrated by following the procedures embedded in F16 (Zero) and F17 (Span) of the Setup Menu. Each procedure enters a value into the indicator's non-volatile memory - F16 the zero value (deadweight) and F17 the span value (test weight). The minimum test weight that can be used is 1% of full-scale capacity.

  • Page 28: View Calibration Values (F18)

    4. After setting the exact value, press the NET/GROSS key to save the value. 5. If the calibration was successful, the display will show "EndC1" momentarily, then revert back up to F17. At this time it is suggested that the calibration values be recorded for future use (see Section 6.4).

  • Page 29: Key-In Span Calibration Value (F20)

    KEY-IN SPAN CALIBRATION VALUE (F20) Note: This procedure is intended for emergency use only in the case of non-volatile memory loss. A valid span calibration value, obtained from a successful F17 calibration procedure, must be used. 1. While in the Setup mode, scroll to "F 20", then scroll down once using the ZERO key. 2.

  • Page 30: Chapter 7: Operation

    CHAPTER 7: OPERATION 7.1 DISPLAY The Model S750-8/S750S-8 indicator utilizes a 6 digit LCD (Liquid Crystal Display) to display the weight and system information while the Model S750/S750S indicator utilizes a 6- digit LED (Light Emitting Diode) display. Typically, LCD’s are used for outdoor applications while LED’s are used indoors where brightness is needed.
