TM 5-3895-374-24-1 The next internal count reading is 1413 counts.  The difference between it and the current average (1330) is 73 counts.  This value falls between Average Shift 1 (4) and Average shift 2 (500) Therefore the new value is shifted in once. 3rd Cycle new reading 1 2 3 4 5 6 7 8 9 10 1250 --? 1413* 1410 1410 1410 1410 1410 12501250   1250   1250   out -- (lost) -  average of 10 registers = 1346 counts = 134 lb.  (disp.  wt.) - - -  The next 4 new readings all fall within the same range as the scale has reached stability after the application of the weight. After 4 more cycles and  4 more shifts the register looks like this: 7th Cycle 1 2 3 4 5 6 7 8 9 10 1411 1412 1411 1412 1413*1410 1410 1410 1410 1410 - Average of 10 registers = 1411 counts = 141 lb.  (disp.  wt.) From the above example note the rapid change in the average counts reading over the first two cycles and the slower change over the subsequent cycles as the average counts approaches the correct reading. If a change in weight on  the scale is  large enough to make  the difference between the current average and the new internal counts reading to be greater than 1000 counts (Average Shift Value 3) then the new reading is shifted into the averaging register 10 times in  one cycle (full update).  In this mode no averaging takes place since all 10 registers record the same reading.  This full update mode will continue until the change in the internal counts reading falls into the range of values below that set by Average Shift Value 3.  Then the averaging system will take over and the weight display will update more slowly as it approaches the correct reading. In Summary RATE OF CHANGE OF DISPLAYED WEIGHT --- NO REGISTERS LOADED NO UPDATE Average Shift Value 1 ---LOAD 1 REGISTER AVERAGING Average Shift Value 2 --- LOAD ½ OF REGISTERS 12 UPDATE Average Shift Value 3 --- LOAD ALL REGISTERS FULL UPDATE Guidelines for setting Average Shift Value 1, 2 and 3 Parameters 41, 42 and 43 Average Shift Value 1 (Parameter 41) - factory set at 3 counts. This parameter should be set for no more than 1/2 of a graduation.  i.e.  If a scale has been met for 5000 graduations at 60,000 counts  then 12 counts = 1 graduation.  In this case Average shift Value 1 should be set for 4 or 5 counts.  If set too low then the scale display will appear unstable.  If set too high then the sensitivity will be reduced and the display may not respond to a one graduation change in applied weight. Average Shift Value 2 (Parameter 42) - factory set at 500 counts. This parameter should be set to two times the amount of change caused by normal motion while load is on the scale.   i.e.  for a livestock scale observe the amount of change in raw counts as the livestock are being weighed and set the value for this parameter to twice the observed change.  Other applications - change caused by liquid sloshing in tanker truck, change caused by truck engine running.
