4.0 Calibration The DC-530 Counting Scale is a high-precision instrument. Although the scale needs very little maintenance, you may want to check the calibration after every month or so of normal usage. To do this you will need to have a test weight of approximately the total capacity of the scale (i.e. a 10 lb weight if you have a 10 lb capacity scale). After the scale is initially installed, put the weight on the platform and record the weight displayed.
full capacity of the scale (i.e. a 10 lb weight for 10 lb capacity scale, etc.) If the reference weight is not equal to the full capacity of the scale, it must at least be greater than 10% of the full scale capacity. Enter the value of the weight placed on the platter using the numeric keys before pressing the # [CODE] key. The weight you enter will appear at the bottom of the display. Press the # [CODE] key. 8.
5.0 Scale Operations The following sections contain detailed operator instructions for the DC-530 counting scale. Included are instructions on how to enter tare weights, accumulate tare weights, establish unit weights, accumulate item counts, perform negative counting, and count parts in both Normal Counting Mode and TEP (Teraoka Error Prediction) Mode. When performing all weighing and counting operations, the scale must be stable before it will accept an entry.
5.2 Teraoka Error Prediction (TEP) Function The DC-530 counting scale includes the DIGI TEP (Teraoka Error Prediction) Function which detects weight variances in sample quantities and calculates the maximum quantity of that piece that can be counted without introducing error. To make the operator’s job easier, the scale’s display will change from green to yellow or red when the maximum safe quantity has been exceeded.
the TARE key. The weight display will now show 0 and the Net and Zero indicator lamps will illuminate. 3. Remove the container, box, or item from the scale.

quantity using the numeric keypad before pressing the PCS key. 4. To improve the accuracy of the Unit Weight calculation, add another sample of the same pieces. This second sample should be of a number of pieces equal to or fewer than the first one. Press the PCS key. (NOTE: If Specification 53, Bit 2 is set to the default setting of 1: Automatic, the scale will automatically begin recomputing.
4. You can now begin counting operations by placing a quantity of the pieces to be counted on the platform. The scale will display the number of pieces as well as the Total Weight, based on the Unit Weight you keyed in. To store this Unit Weight in the DC-530’s memory associated with an Item Code so that you can recall it in the future, see Section 6.2.1. 5. To clear the Unit Weight, remove all weight from the scale platter and press the C (Clear) key. 5.5.
7. To print a label showing the total, press the * PRINT key. Figure 5-1. Total Accumulation Label Sample 8. This will also clear the accumulation register. The ACC (Accumulation) indicator lamp will no longer be illuminated. 9. To clear the Unit Weight, remove all weight from the scale platter and press the C (Clear) key. 5.5.
3. Remove Container 1 from the platform. 4. Place Container 2 (full of parts) on the scale. 5. Press the - (Minus) key to subtract the new quantity from the total. The display will show the total which will be the difference between Container 1 and Container 2, then return to the Normal Counting Mode screen. 6. Repeat steps 4 and 5 for all the containers to be subtracted from the total. 7. To print a label showing the total after all the subtractions, press the * PRINT key. Figure 5-2.
NOTE: To perform Negative Counting, SPEC 52, Bit 1 must be set to 1: Yes. This is the default setting. 5.5.7 Counting Out of a Full Container - See Total Amount Remaining in the Container To carry out this operation you must know the tare weight ahead of time. 1. Press the REZERO key to zero the scale. 2. Place the full container on the scale. Press the TARE key. 3. Remove a 10 piece sample from the container and press the PCS key.
1. Press REZERO to zero the scale. 2. Press the TEP key to enter the Teraoka Error Prediction Mode. 3. Count out a number of parts to be sampled and place them on the scale (for example 10 pieces). For maximum accuracy, count the 10 piece sample into your hand and then add the entire sample to the bin at one time, instead of adding them one or two at a time. 4. Enter the sample quantity using the numeric keypad, then press the PCS key.
6. When the sample weight is within the required range, the scale will recompute the Unit Weight and return to the TEP Sampling screen. The scale display will show the new total Weight, Unit Weight, and number of Pieces. It will also now indicate that you have been SAMPLING 2 TIMES. 7. Continue resampling by repeating Step 5, adding another sample below the amount shown on the TEP Mode display.
platform. The scale will display the number of pieces as well as the Total Weight, based on the Unit Weight established by the sampling process. To store this Unit Weight in the DC-530’s memory associated with an Item Code so that you can recall it in the future, see Section 6.2.1.
without error. 2. Press the REZERO key to zero the scale. 3. Place on the platter a quantity of parts to be counted. 4. If the quantity is less than the accuracy limit, the scale will display the count of the number of pieces and reduce the maximum limit to how many more can be counted under the limit. Add pieces up until the quantity limit is reached, then remove the parts from the platter and begin counting again. 5.
5.6.5 TEP Mode - Negative Counting Negative Counting in TEP Mode follows the same procedure as in Normal Counting Mode but you must first establish a Unit Weight by sampling in the TEP Mode. For more information on establishing TEP unit weights, please see Section 5.6.1. For information on negative counting procedures, please see Section 5.5.6 5.6.6 TEP Mode - Clearing Accumulated Data To clear accumulated data, press the * PRINT key. 5.
