Counting scales have become an essential tool for accurately counting large quantities of small parts. The DIGI® DC-782 Counting Scale available from Central Carolina Scale is a low cost solution for many parts counting needs. While withstanding frequent movement, the DIGI® DC-782 also maintains the incredible resolution and accuracy needed for dependable parts counting. This electronic counting scale can be programmed to store information for up to 25 separate parts, as well as interface with a PC using its RS-232 output. Use the DIGI® DC-782 for up to 300 hours of continuous use on its optional rechargeable battery. For mobile workstations, outdoor applications, warehouses, or rental scales, be certain your count is correct using the DIGI® DC-782.
The DC-782 is a low cost counting scale that offers practical solutions for a full range of counting applications. Its counting resolution of 1/500,000 gives you maximum counting precision and accuracy. Its backlit LCD display enables operators to easily see weights and quantities. The DC-782 can also store an item code, tare weight, unit weight, and setpoint value for 25 of your pieces, parts, or items and recall 10 of them with the pressing of a single preprogrammed key. The DC-782 digital counting scale is rugged enough to operate reliably in many environments and withstand transport from one area of the plant to another or from one business to the next.
Counting scale accuracy is primarily determined by the following factors:
•Sample size (number of pieces)
•Total sample size as a percentage of full scale capacity
•Piece-to-piece weight variation
As a general rule when determining sample size of fairly uniform pieces, the larger the sample size the greater the total sample weight, therefore, the better the counting accuracy. Selecting the smallest capacity scale that can obtain the highest counting resolution should be considered, but should not sacrifice the capacity required for the heaviest container of parts. There is a direct relationship between piece-to-piece weight variation (non-uniformity) and counting accuracy. Therefore, elimination of the piece-to-piece weight variations can be accomplished by:
1.Isolating the sample used to calculate the unit weight and use the same sample to re-check the scale.
2.Recalculating the unit weight from lot-to-lot of parts. Parts manufactured on one machine may vary slightly from another machine relative to weight.
3.Tightening the manufacturing tolerances on the parts reduces piece weight variations and increases count accuracy.
Parts can vary greatly in their value. With parts of lesser value per piece, the extra sampling and time involved in trying to achieve 100% accuracy as opposed to 99.5% may not be cost-effective. However, with high value items, 100% accuracy is vital. DC-782 Counting Scales have the precision to help you with both situations.
The DC-782 is available in the following capacities:
6 lb x 0.001 lb
15 lb x 0.002 lb
30 lb x 0.005 lb
60 lb x 0.01 lb
