TM 5-3895-374-24-1 Load Cell Full Scale Output. (14 mv) This parameter represents the output of the load cell, in millivolts, at maximum scale capacity The range of entries allowed is from 8 (mv) to 35 {mv). This entry acts as a coarse span or span range adjustment for the Indicator, matching It with the working range of the load cell Note: In order to achieve the rated performance from the indicator. This parameter must be set accurately. Please refer to Section III Calibration for Information on how to determine the value of this parameter for your scale 12. Set Dead Load The DF2000 now features an automatic compensation for the scale deadload When you have selected this function, press [ENTER]. The indicator will then enter a routine to zero the deadload. While this routine is in progress, a flashing ’d’ will replace the flashing ’I’ in the leftmost display digit. Upon completion of the deadload routine, the flashing ’I’ will return and the weight display will be at or near zero. Note The automatic deadload routine will not work if the deadload is greater than the value entered for Load Cell Full Scale Output (Parameter 11). 13. Set Span. This function is used to set the fine span for the indicator. Please refer to Section III Calibration for information on how to set the span. 14. Reset Dead Load. Returns the indicator to the factory deadload setting. When you have selected this function, press [1 I[ENTER] to perform this operation. 15. Reset Span Table. Clears the span table except for the first entry. Do this before calibrating the indicator. When you have selected this function, press [11 (ENTERI. Note this will clear any previous calibration. 16. Increment Span Pointer Allows you to make a second span adjustment to correct a scale linearity error. When you have selected this function, press (II IENTERI. See Appendix [I for information on how to use the second span adjustment. Note 1: The span pointer cannot be incremented past 2. Note 2: Unlike the DF1000, the DF2000 span pointer is not incremented automatically each time Set Span (Parameter 13) is selected. 17. Decrement Span Pointer. Brings the span pointer back to the first span adjustment. When you have selected this function, press I11 [ENTER]. Note: The span pointer cannot be decremented past 1. 21. Push to Zero Window. (2) Represents the percentage of scale capacity that can be zeroed by the Push to Zero key. The allowable range is 0 to 99 (%) of overweight value. This should be set to 2 1%) in most cases. 22. Auto Zero On-Off. (1) Controls the automatic zero tracking function. Set to (1) to enable auto zero, set to {0) to disable auto zero. When this function is enabled, the ’ZERO’ light will be on when the scale is at zero. Note: You must disable the auto zero to accurately check scale sensitivity at zero. 23. Auto Zero Window. (60) Determines the amount of change that can be tracked by the Auto Zero function. The allowable range is from 0 to 99 1%) of I graduation per 0.25 seconds. This should be set to 60 I%) in most cases. (page 3-67)
