30 DC-530 Operation Manual
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. After the Unit Weight has been
calculated, return the 10 piece sample to the container.
4. Remove a number of parts from the container and press the + (Plus) key. The memory indicator lamp
(ACC) is illuminated and the display shows the quantity of parts taken out.
5. Remove a number of parts from the container and press the + (Plus) key again. The memory indicator
lamp (ACC) will be illuminated and the display shows the quantity of parts removed.
6. If at the end of the procedure, if you want to see how many parts are still in the bin you first have to know
the tare weight of the bin or container. After removing the parts you want to take out of the bin, simply
digitally enter the tare weight of the bin and press the TARE key. The scale will display how many parts
were left in the bin. To print a label to put on the bin showing the new, lower, total quantity in the bin ,
press the
+ (Plus) key.
5.5.8 Negative Counting - Total Removed Displayed at the End
With this procedure you can count accurately out of a full container for kitting, shipping, etc. without having to
know the tare weight of the container.
1. Press the REZERO key to zero the scale.
2. Place a full container on the scale and press the TAR E key.
3. Remove a 10 piece sample from the container and press the PCS key. After the Unit Weight has been
calculated, return the 10 piece sample to the container.
4. Remove the number of pieces you need for kitting, shipping, etc. The amount removed will be
displayed. If you need a label for each kit or container, press the + (Plus) key after removing each batch
of pieces. Then press the
TARE key.
5. When you have removed the last batch of pieces, press the * PRINT key to show the total number of
pieces you have counted out of the full container.
5.5.9 Normal Counting Mode - Clearing Accumulated Data
To clear accumulated data, press the * PRINT key.
5.6 Operations in TEP (Teraoka Error Prediction) Mode
Unit Weight Entry, Counting Operations, Accumulation and Subtraction can be done either in Normal Counting
Mode or in TEP (Teraoka Error Prediction) Mode. This section (
Section 5.6) will cover operations in TEP Mode.
For operations under Normal Counting Mode, see Section 5.5.
The TEP Counting Mode is generally used for high-value parts for which you want to avoid even the generally
very small counting errors introduced by sample variances. A repeated sampling procedure allows the DC-530
scale to develop weight variance plots and thereby calculate a maximum safe quantity that can be counted
without error. The extra sampling effort required has to be balanced against the need for the greatest possible
accuracy.
5.6.1 TEP Mode - Unit Weight Operation by Sampling
Entering unit weights can be done either by sampling, as presented in Section 5.6.1, or by manual key entry as
described in Section 5.6.2.
NOTE: SPEC 53, Bit 0 TEP SAMPLING METHOD controls whether or not you have to push the PCS key to recompute the Unit
Weight after resampling. The default is “1: Automatic” which means that you do not have to press the PCS key except after
placing the very first sample in the sampling process.
Unit Weight operation by sampling is accomplished by placing a sample on the scale, entering the sample
quantity, and then pressing the
PCS key. The scale calculates a Unit Weight based on the capacity of the scale
compared to the weight of the sample.
