How To Use A Counting Scale

One standard question that we receive quite often is, how to use a counting scale or how does a counting scale work? The easiest answer is to manually count out ten of the same parts and place them on the scale. Then let the scale determine the average piece weight and at that point you can add more of those same parts to the scale and the scale will automatically count them for you.

Sounds pretty simple doesn’t it? Sometimes it can be that simple, but there are other factors that develop which can cause some problems. First, as we’ve mentioned before in our counting scale reviews, some scales for counting parts are easier to use than other models. If a scale is hard to use it might lead to more potential user error or have a negative impact on counting scale accuracy. Every now and then a customer will ask what is the best counting scale? That can be tricky to answer since there are actually a number of pretty good scales in the market place.

If you’re having a tough time figuring out which scale will work best for you, we suggest taking a look at the user manual or instructions. This will give you some insight into the basic operation of the scale and give you a basic overview of how the scale works.

Counting scale sample size can be very important too. This is really the foundation for the accuracy of your parts counting efforts. Your parts need to be the same weight and you need to get a good average piece weight. One of the easiest ways to do that is by getting a good sample. It doesn’t matter if we’re talking about the Digi DC782 scale or the old Digi counting scale dc 80.  If you do this correctly, you will virtually eliminate error and establish excellent levels of accuracy on all your counts.

Basic Counting Procedures for the B130

Below is an overview on how to use the Brecknell B130 counting scale for basic counting of parts.

Counting by Sampling
Follow these steps to count items using the sampling method. For count accuracy all items should be uniform in weight. Errors in count will occur if
parts vary in weight.

1. Turn the scale on and zero the display, if necessary, using the Zero key. Be sure the scale is displaying weight in your preferred unit of measure. Change it
using the Units key, if necessary.
2. Place a known number of objects on the scale. This is the sample weight the scale will use to calculate a piece weight… Weight of the items is displayed in the WEIGHT window.
3. Key in the number of objects you placed on the scale… SPL.PCS is displayed in the PIECE WEIGHT window and the number you keyed in is displayed in the COUNT window.
4. Press the Enter key to accept the keyed in number. (If you make an error in keying in the number, press the Clear key to clear the count in the COUNT
window and re-key the correct number.)… The scale calculates the weight of each piece (the piece weight) and displays the count in the COUNT window.
5. Place the items to be counted on the scale… The total weight, piece weight and count of the items will be shown in the three display windows respectively.
6. Remove the items from the scale and repeat steps 5 and 6 to count items of the same piece weight.
7. Repeat steps 1-6 to count items of a different piece weight. Counting can also be done while using a tare. After you have set the piece weight
(step 4), place the item to be tared on the scale, press the Tare key and continue with counting as described in step 5.

Note: Piece weight is displayed in grams/decimal grams or LB/decimal pounds.

Note: The original piece weight will be held in memory until a new piece weight has been determined. Turn the scale off, then on to return to normal weighing mode.

Counting by Entering a Known Piece Weight
You can enter a known piece weight and begin counting without sampling. This can also be used with the tare function active. After you have set the piece weight, place the item to be tared on the scale, press the Tare key and continue with counting as described below.

Follow these steps:
1. Turn the scale on and zero the display, if necessary, using the Zero key. Be sure the scale is displaying weight in your preferred unit of measure.  Change it using the Units key, if necessary.
2. Press the Pcwt key… PC.t is displayed in the COUNT window and zeroes are displayed in the WEIGHT and PIECE WEIGHT windows.
3. There is a decimal point already in the PIECE WEIGHT window. Key in the known piece weight, in decimal pound or grams, using the numeric keypad so that the piece weight in the PIECE WEIGHT window is correct, then press the Enter key to accept this piece weight. (If you make an error in keying in the number, press the Clear key to clear the number and re-key the correct number.)
The counting mode activates using the entered piece weight.
4. Place the items to be counted on the scale… The total weight, piece weight and count of the items will be shown in the three display windows respectively.
5. Remove the items from the scale and repeat steps 4 and 5 to count items of the same piece weight.
6. Repeat steps 2-5 to count items of a different piece weight.  Counting can also be done while using a tare. After you have set the piece weight (step 3), place the item to be tared on the scale, press the Tare key and continue with counting as described in step 4.
