TM 5-3895-374-24-1 *To check a parameter,  press  the number for that parameter followed by the [SELECT] key.  For example: To check graduation size (Parameter 3)   Press [3]  [SELECT]. To check push to zero window (Parameter 21):   Press [2] [1] [SELECT]. When you have accessed a parameter via the above procedure,  the indicator will then display the current value for that parameter.  If you wish to change the value, check the Parameter List, Section IV, and enter a new value by pressing the appropriate numbers  followed by the [ENTER] key.  Examples of this procedure will be given in the following steps. [1] [SELECT] Reload Factory Values.  A  set of factory values for all parameters is available to make the indicator easier to use initially.  After you have selected this function, press [ENTER] and the factory values will be loaded.  Note this will clear any previous calibration. [2] [SELECT] Decimal Point Position.  Set the decimal point position to correspond with the graduation size.  For example, for a .05 lb. Graduation size, press [2]  [ENTER]:  for a 10 lb. graduation size, press [0] [ENTER]. [3] [SELECT] Graduation Size. Set the graduation size from the Parameter List, Section IV, making sure that the displayed units  (LB/KG) are appropriate for the graduation size you select.  (To change the displayed units, LB/KG.  select Parameter 7.) For example: For .05 lb.  grad size, press  [ . ] [0] [5] [ENTER]. For 10 lb.  grad size, press [1] [0] [ENTER]. [4] [SELECT] Overweight.  Set to one graduation  over  the maximum  capacity of the scale.  This  number must be less than 5000 displayed graduations. For example: For 2 lb.  grad size and a maximum capacity of 5000 lbs., press [5] [0] [0] [2] [ENTER]. [5] [SELECT] Motion Window.  Set to two times the graduation size.  Note this value is automatically set when you set the graduation size.  For example: For .05  lb. grad size, press [ . ] [1] [ENTER] For 10 lb.  grad size, press [2] [0] [ENTER]. [6]  [SELECT] Power On Units.  Set to the units (LB/KG) that you wish the unit to be in whenever it is powered up.  For example To power up in KG mode, press [1] ENTER To power up in LB mode, press [0] ENTER. [8]  [SELECT] USA  Display Flag.  Set this parameter to ’0’  for Canada and to ’1’ for the USA   For example: To make  the indicator  legal for trade in the U S.A.  press [1] [ENTER]. [9] [SELECT] Power On Reset Warning.  This parameter should be set to ’1’ for a "Legal for Trade" scale [21]  [SELECT] Push  to Zero Window.  Set this parameter ’2’ for a ’Legal for Trade’ scale.  This value represents the percentage of scale capacity that can be zeroed by the Push to Zero key [22] [SELECT] Auto Zero On-Off.  If you wish to turn off the automatic zero tracking   function, press [5]  [ENTER]. To restore auto zero press [1] [ENTER]. [23] [SELECT] Auto Zero Window.   Set this parameter to ‘60’ for a "Legal for Trade" scale.  This value represents a percentage of one graduation.  The maximum amount of weight change per 1/4 second, that will be automatically zeroed. [24] [SELECT] Motion Settle Time.    Enter  the number of .25 second  intervals for which motion will remain asserted after the scale stabilizes to within the Motion Window (Parameter 5).  Factory set 16 (4 seconds).  For example To set to 2 seconds, press [8]  [ENTER] (page 3-63)
