Internal Resoultion in Counting Scales
In today's world more than ever, companies are trying to account for smaller components in their inventory. You can do the count by hand, however it is an extremely tedious task and takes up tremendous amounts of time and effort. One great way to do parts inventory is with a digital counting scale. When attempting to purchase a counting scale, often times the consumer can easily be confused by all the terminology in the marketplace. In this article, with the help of our friends at Rice Lake, we discuss internal resolution and external resolution.
The internal resolution of a counting scale is the number of divisions into which it divides the total capacity of the scale.
Example: A 50 lb counting scale with 1 million count resolution divides up the 50 lb into 1,000,000 parts. This means each internal resolution is translated to 50/1,000,000 or 0.00005 lb.All of the weights are calculated on this basis. For example, if some parts were placed on the counting scale, and the internal calculation was 210 internal counts, the weight to be displayed would be 210 times 0.00005 lb = 0.01050 lb. Since the weight display might only be five digits, then the weight display would be 0.01 lb. This is the external resolution. (rounded off).
The operator can key in the sample quantity—for example, ten pieces. The scale still "knows" how many internal counts are being used (210) and now divides that number by 10 to get the number of internal counts per piece (210/10 = 21).
Next the scale needs to convert the piece weight into pounds, by simply multiplying the weight per count times the number of counts (0.00005 times 21) = 0.00105. This is displayed in the Unit or Piece Weight window.At this point the scale need only watch for a change in the weight and redo the calculation in reverse, using the number of internal resolutions per piece as the divisor. For example, more pieces are placed on the scale and the number of internal resolutions is now 187091. So 187091 / 21 = 8909.09 which is rounded to 8909 pieces.
Somewhat related, the external resolution is what is displayed in the weight window of a scale. It is also called display resolution and is calculated by taking the capacity of the scale and dividing by the resolution. In most load cell based counting scales, the external resolution will be one part in 10,000 also expressed as 1/10,000.The displayed resolution is not as important in a counting scale since the calculations are all made using internal resolution. The only time the external resolution comes into play is when a tare weight is being manually or digitally introduced. If the value of the tare container is rounded, this can result in a less accurate count. All this is sure to make your task easier and more productive. Parts counters also come at very affordable prices. To learn more about the counting scale you can visit www.centralcarolinascale.com

when counting calories do you include drinks?
the scale says that i'm losing weight and i feel better but i'm worried about the calories that are in grape juice and apple juice.
I drink alot of water during the summer
but the winter i drink allot of motts apple juice and grape juice
do u include these extra calories?
i'm going to the bathroom like crazy lol
there is no corn syrup in apple juice
You must count your drinks like apple juice and grape juice in your calorie totals.
You would be wise to eat your apples and grapes fresh and cut out the apple and grape juice. They have lots of high fructose corn syrup in them and the calories in those drinks can add up to a lot.
