About This Manual

This manual contains operating procedures for the DC-530 counting scale and provides the user with all the
information necessary for its setup and operation. It is organized based on the procedures you will likely follow
when setting up and using your counting scale. This manual applies to Version 2.01 of the DC-530 counting scale
series.

Some procedures described in this manual require work inside the scale base. These procedures are to

1.0 Introduction

The DC-530 is high-precision counting scale that offers practical solutions for a full range of counting
applications. With an internal counting resolution of 1/1,000,000, the UniBloc one-piece force cell design
provides quick response, stability against temperature change, and outstanding durability on top of maximum
counting precision and accuracy. Its high-visibility full dot color LCD display enables operators to easily see
weights and quantities. Counting and weighing operations are greatly speeded by the DC-530’s ability to store
and recall the item code, tare weight, unit weight, and three setpoint values for 200 of your pieces, parts, or items.
The RS-232 ports allow you to connect to a printer, PC, or barcode scanner, while the optional remote scale
channel lets you add another weighing platform.

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. This function works by performing a series of sampling
operations which the scale uses to plot the weight variances of the pieces being weighed. By then accumulating
counting results within the calculated safe quantity, the counting operation can be completed without a counting
error.

1.1 Capacities and Resolutions

Table 1-1 lists the scale capacities, minimum graduations, and tare ranges for all models of the DC-530 counting
scales. The internal count span and display resolution can be set by the user in the weight and measurement
specifications (See Section 3.X). Weight units can also be set between lb and kg using the scale’s weight and
measurement specifications.

2.4.2 Start-Up Screens

1. When powering up, the DC-530 will display the model number and firmware version.

2. Next, the scale tests the color modes of the display and says SEARCHING SCALE before bringing you to the
Normal Counting Mode screen

.

3. If there is anything on the platform(s) and it exceeds the scale start range, the display will show the error
message Out of start range. If this error appears, remove the weight from the platform and the scale
will continue its startup sequence.

2.5 Setting the Date and Time

Once the date and time have been set, the internal clock will be maintained by the main board battery even when
the DC-530 is not plugged in or turned off. The procedure below can also be used to adjust the time when
moving from Standard to Daylight Savings Time or when the scale is moved to a new facility in a different time
zone.

1. Press the MODE key until the display shows the Menu Screen.

2. Press the 3 key to enter the Date and Time Setting Screen.

(NOTE: The order in which the day/month/year fields appear on the screen may vary depending on how you scale is
programmed.).

3. Use the numeric keypad to enter the current date (2 digit format). Then press the + (Plus) key to move to
the setting of the month.

4. Use the numeric keypad to enter the current month (in 2 digit format). Continue forward to the other
fields by pressing the + (Plus) key. To move backwards to a modify a previous field, press the [-]

(minus)

key. To move to the next field without making any change, simply press the + (Plus) key

without entering data.

5. When all the date and time fields have been entered, press the * PRINT key to save the date and time
setting. To exit without saving the changes, press the TAR E key to return to the Mode Menu screen.

6. Press the [1] key to exit the menu and return to the Counting Mode Screen.

3.0 Configuration Settings

This section presents the setup and configuration of the DC-530 Counting Scale to be used specifically by
distributors and service technicians. Configuring these specifications allow you to tailor the DC-530 to your
specific applications.

Setting the specifications allows you to modify the functionality of the DC-530. Use the tables in this section to
view the options you can modify. For example, if you want to deactivate the DC-530’s ability to enter Tare
weights digitally, refer to the specification table and locate SPEC 35, Bit 2. The default for SPEC 35 is 1, which
means it is enabled. To turn it off or disable it, change the SPEC setting to 0: No.

The following tables list the DC-530 specifications and their corresponding default values. The default values are
automatically set when the scale’s memory is initally set by the dealer.

SPEC 00 through SPEC 12, and SPEC 51 through SPEC 55 (Table 3-1) are Customer Specifications while SPEC
20 through SPEC 49 (Tab le 3-2) are Weight and Measurement specifications. In programming specifications, the
+ (Plus) and – (minus) keys allow you to move to the next or previous specification while saving changes to the
SPEC code you were just in. To exit from a specification without saving your changes, press the TARE key. To
save the changes when exiting, press the

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. Then
every month or so put the same weight on the scale and verify that it still reads the same.

Many facilities have a technician come in and check their units with certified test weights four times a year. If
you are ISO certified, you will want to check to see if your certification specifies more stringent requirements in
order to stay in compliance. Your Rice Lake Weighing Systems scale dealer has the calibrated test weights,
expertise and experience to perform this task for you as well as to check other operating parameters of your scale
and help you effectively integrate scales into your operations. If you do not know who your local Rice Lake
Weighing Systems dealer is, call us at 1-715-736-0002 and we will help you find someone who can provide you
with on-site support.

Follow the instructions below to calibrate your DC-530 scale to ensure its continued accuracy.

NOTE: You can exit the Maintenance Mode and return to the Counting Mode at any time by pressing the TAR E key.

1. Ensure that there is no weight on the platter and turn the scale on. It will display the model number and
current firmware version number.

2. With the scale in the Counting Mode, press the MODE key to go to the Mode Menu.

3. While at the Mode Menu, press and hold the REZERO key while entering 8715 from the numeric
keypad to enter the calibration mode.

4. You can select which scale you are calibrating, Scale 1 or Scale 2, by pressing the SCALE key. (If a 2nd
scale is not installed and set in the specifications, pressing the

5. The scale display will ask you to make sure that there is no weight on the platter then press the #
[CODE] key to set the zero point..

6. The scale will briefly flash the message ZERO POINT SETTING, please WAIT...Once the zero point is set, the
display returns to the Calibration Screen.. Press the * PRINT key to move to the span weight calibration.
The display will change to the following:

7. Place a reference weight on the platform. It is preferable to calibrate the scale using a weight equal to the

20 DC-530 Operation Manual

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. The display will flash briefly again as the span settings for calibration of the scale are being saved, then
the display will return to Mode Menu.

9. Press 1 exit the Mode Menu and return to the Counting Mode.

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.
The scale will indicate that the weight reading or count is stable by illuminating the Stable indicator lamp. If you
press a function key when the scale is not stable you will hear a double beep indicating that the function cannot
be performed yet. Once the Stable indicator lamp is lit, then perform the function.

Figure 5-1. DC-530 Counting Scale

5.1 Factors Affecting Counting Scale Accuracy

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 and 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. For some applications, a dual-platform scale utilizing the DC-530’s optional
capability to connect a second scale may be the best selection.

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 will greatly improve accuracy. This can be
accomplished by:

• Isolating the sample used to calculate the unit weight and use the same sample to re-check the scale.

• Recalculating the unit weight from lot to lot of parts. Parts manufactured on one machine may vary
slightly from another machine relative to weight.

• Tightening the manufacturing tolerances on the parts reduces piece weight variations and increases
count accuracy.

22 DC-530 Operation Manual

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. This function works by performing a series of sampling
operations which the scale uses to plot the weight variances of the pieces being weighed. By then accumulating
counting results within the calculated safe quantity, the counting operation can be completed without a counting
error. Although the TEP Function can be used at any time the scale owner or operator deems it appropriate, the
extra sampling involved to derive the plot make it most logical for high-value items.

Coupled with the DC-530’s internal counting resolution of 1/1,000,000, the TEP Function assures your precise
counting of high-value items.

5.3 The Mode Menu Screen

The starting point for using the DC-530 scale is the Mode Menu Screen. From this screen you have four options
to choose from:

1. Counting Mode - to enter the Counting Mode Screen on which weights and counts are displayed;
2 - Program Mode - to enter the Program Mode Screen where you will be able to further choose between

editing and deleting items in memory;
3 - Date and Time - to enter the Date and Time Setting Screen; and
4 - Set Point Settings - to enter the General Set Point Setting Screen in which you can establish set points

not associated with specific items in memory.

Figure 5-2. Mode Menu Screen

To select the option desired, simply press the number key for the corresponding number on the numeric keypad.
The display will change to the screen for that option.

5.4 Tare Operation

Tare weights can be entered in the scale by one of two methods: one-touch tare or digital tare. Digital tare is used
when the tare weight is already known, while one-touch tare is used when the tare weight is unknown. If you call
up an Item Code already programmed into the DC-530’s memory and you have a Tare Weight stored for that
Item Code, the Tare Weight stored with the Item Code will override one entered digitally or by using the TARE
key. The procedures illustrated below are the same for the Normal Counting Mode and the TEP Counting Mode
although only Normal Counting Mode displays are shown in the examples.

NOTES:

• SPEC 35, Bit 2 DIGITAL TARE SETTING must be a “1: YES” to allow digital tare.

• SPEC 35, Bits 1 and 0 TARE RANGE must be set to the appropriate tare range value. The default is “00: 100 PERCENT OF
FULL SCALE”.

• SPEC 37, Bits 3 an 2 DIGITAL TARE ROUNDING determines if a digital tare is stored as entered or rounded to the nearest
increment. The default is “01: Round to Nearest Increment.”

• SPEC 47, Bit 1 ZERO LAMP CONDITION determines whether the zero indicator lamp lights when a gross weight is being
displayed or a net weight. The default is “0: GROSS”.

5.4.1 One-Touch Tare, Tare Unknown

1. Press the REZERO key to zero the scale.

2. If the tare weight value is not known, place the container, box, or item to be tared on the scale and press

Scale Operations 23

the TA R E 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. The weight display should show a negative weight
value (weight of the tared container, box, or item).

4. To clear the tare weight, press the TARE key. The Net indicator lamp will no longer be illuminated.

5.4.2 Digital Tare, Tare Weight Known

1. Press the REZERO key to zero the scale.

2. If the tare weight value is known, use the numeric keypad to key in the value and then press the TARE
key. The Tare Weight value must be entered without a decimal point. The Weight field is 5 digits long
and the placement of the decimal point is determined by Bits 2, 1, and 0 of Specification 21 - Weight
Decimal Point Position. The digits you enter for the tare weight will fill the field starting from the right.
(Example: if the decimal point is set as 0.0000 and you enter the digits 125, the net weight will show as

0.0125.) The Net indicator lamp will illuminate.

3. To reset the tare to zero, press the TARE key again.

5.4.3 Tare Value Accumulation and Subtraction

Tare weights can be accumulated or subtracted using the TARE key by the One Touch Tare method. Tare
weights can also be accumulated using the Digital Tare method, but not subtracted.

NOTES:

• SPEC 35, Bit 2 DIGITAL TARE SETTING must be a “1: YES” to allow digital tare.

• SPEC 35, Bits 1 and 0 TARE RANGE must be set to the appropriate tare range value. The default is “00: 100 PERCENT OF
FULL SCALE”.

• SPEC 37, Bits 3 an 2 DIGITAL TARE ROUNDING determines if a digital tare is stored as entered or rounded to the nearest
increment. The default is “01: Round to Nearest Increment.”

• SPEC 38, Bit 3 DIGITAL TARE WHEN LOADED must be set to “1: YES” in order for bo t h O n e To u c h Ta r e a n d D i g it a l Ta r e
functions to be used at the same time.

• SPEC 46, Bit 3 TARE INCREASE and SPEC 46, Bit 1 OVERWRITE THE TARE must both be set to “1: YES” to allow

24 DC-530 Operation Manual

accumulation of tare values. To allow Tare Subtraction, SPEC 45, Bit 3 TARE DECREASE must be set to “1: YES”.

5.4.4 Tare Accumulation

1. Press the REZERO key to zero the scale.

2. At the Counting Mode Screen, place the container, box or item to be tared on the platform and press the

TARE key. The Weight Display should now show 0 and the NET indicator lamp will illuminate. If you
enter the Tare Weight digitally and press the TARE key, the Tare Weight will show in the Weight
Display with a minus sign in front of it and the NET indicator lamp will illuminate.

3. Place another item to be tared on the platform and press the TA R E key again. This will add the two tare

weights together (Tare Accumulation). When using Digital Tare entry, the next tare weight value should
not be lower than the previous one. If you enter another tare weight digitally and press the TARE key,
the Weight Display will show the accumulated Tare Weight.

4. Repeat Step 2 until you have accumulated all the tare weights necessary for your weighing and counting
operation.

5. If you remove all the tare weights from the platter, the Weight Display will show the accumulated Tare
Weight.

6. To clear the accumulated tare weights, press the TARE key after removing all the tare weights from the
platter. The NET indicator lamp will no longer be illuminated.

5.4.5 Tare Subtraction

1. Press the REZERO key to zero the scale.

2. At the Counting Mode Screen, place the container, box or item to be tared on the platform and press the
TARE key. The weight display should now show 0 and the NET indicator lamp will illuminate. Tare
subtraction cannot be done digitally.

3. Remove the amount of the tare that you want to subtract and press the TAR E key to subtract it.

4. Repeat Step 3 to subtract more tare weights until you have the desired tare weight.

5. To clear all the tare weight, remove all tare weights from the platter and press the TARE key. The NET
indicator lamp will no longer be illuminated

5.5 Operations in Normal Counting Mode

Unit Weight Entry, Counting Operations, and Accumulation and Subtraction can be done either in Normal
Counting Mode or in TEP (Teraoka Error Prediction) Mode. This section (
the Normal Counting Mode. For operations under TEP Mode, see Section 5.6.

5.5.1 Normal Counting Mode - Unit Weight Operation by Sampling

Entering unit weights can be done either by sampling, as presented in Section 5.5.1, or by manual key entry as
described in Section 5.5.2.

NOTE: SPEC 53, Bit 2 NORMAL COUNTING MODE AUTO-RECOMPUTING controls whether or not you have to push the PCS
key to recompute the Unit Weight after resampling. The default is “1: Auto” 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 10 piece sample on the scale and then pressing

PCS key. The scale calculates a Unit Weight based on the capacity of the scale compared to the weight of the

the
sample.

1. Press REZERO to zero the scale.

2. Place a number of pieces of the item to be sampled on the scale. The DC-530 assumes that you are using
a 10 piece sample unless you indicate otherwise in the next step. For maximum accuracy, count the
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.

3. If you are using a 10 piece sample, simply press the PCS key. The scale will display the total Weight,
Unit Weight, and number of Pieces. If you are using a sample size other than 10 pieces, enter the sample

Section 5.5) will cover operations in

Scale Operations 25

side of the display, you have reached the maximum. Remove some of the pieces in the second sample until the number
of pieces is below that of the first sample.

will appear. You can also tell if you are under the maximum recomputing sample size by observing

MAX marker on the bottom right-hand

If you place too small a sample on the platform for the scale to accurately calculate a Unit Weight, the
INSUFF indicator lamp will illuminate and the display will indicate how many more pieces have to be
added to the sample in order to be able to calculate the Unit Weight. Add the necessary pieces to the
sample until the scale returns you to the Normal Counting Mode screen. The screen will then show

RECOMPUTING before showing the Unit Weight.

5. If you wish to continue to refine the Unit Weight, repeat Step 4, adding another sample.

6. When done with calculating the Unit Weight you can 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 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.

7. To clear the Unit Weight, remove all weight from the scale platter and press the C (Clear) key.

5.5.2 Normal Counting Mode - Unit Weight Operation by Key Entry

Unit weight operation by key entry is accomplished by using the numeric keypad to enter the known value of the
Unit Weight and then pressing the

UNIT WEIGHT key. An example of Unit Weight operation by key entry is

shown below:

1. Press the REZERO key to zero the scale.

2. With the display in the Normal Counting Mode, enter the known Unit Weight using the keyboard, for
example, 200.00.

(NOTE: the Unit Weight is entered and displayed per 1000 pieces. To enter a Unit Weight of 0.0125 lbs, for example,
multiply 0.0125 x 1000 = 12.5. For a Unit Weight of 0.0125, therefore, you would enter 12.5 on the numeric keypad.
When entering Unit Weights you must enter the decimal point where appropriate.)

3. Press UNIT WEIGHT key to enter the Unit Weight.

26 DC-530 Operation Manual

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.

5.5.3 Normal Counting Mode - Part Accumulation and Part Subtraction

Once a Unit Weight has been established for an part, the DC-530 Counting Scale has the capability to
accumulate and subtract total item quantities by using its accumulation memory.

5.5.4 Normal Counting Mode - Part Accumulation

To find the total accumulated quantity of similar containers filled with parts, use the accumulation procedure
detailed below.

1. Conduct a sampling process (Section 5.5.1) to determine the Unit Weight of the pieces and enter a
known tare weight, or place the empty container on the scale to perform the tare function ().
Alternatively, you can enter the Item Code of an item previously programmed into memory and press the
# [CODE] key to recall the data. If you enter an Item Code that is not currently programmed into the
scale’s memory, the message ITEM NOT FOUND will appear at the bottom of the display. For more
information on how to program item data into the DC-530’s memory, see Section 6.1.

2. Place Container 1 (full of parts) on the scale.

3. Press the + (Plus) key to store the total in Container 1. The Acc (Accumulation) indicator lamp will now
be illuminated. The display will show the total quantity of pieces accumulated for 3 seconds, then return
to the Counting Mode screen.

4. Remove Container 1 and place Container 2 (full of parts) on the scale.

5. Press the + (Plus) key (the total displayed is equal to Container 1 plus Container 2, etc).

6. Continue with the remainder of the containers to be counted. The total number of parts stored in all the
containers will be stored in the accumulation register.

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.

5.5.5 Normal Counting Mode - Part Subtraction

Just as you can accumulate total quantities by adding parts to the scale, you can also count by removing parts
from the scale, subtracting them from the total you began with.

1. Conduct a sampling process (Section 5.5.1) to determine the Unit Weight of the pieces and enter a
known tare weight, or place the empty container on the scale to perform the tare function (Section 5.4).
Alternatively, you can enter the Item Code of an item previously programmed into memory and press the
# [CODE] key to recall the data. If you enter an Item Code that is not currently programmed into the
scale’s memory, the message

ITEM NOT FOUND will appear at the bottom of the display. For more

information on how to program item data into the DC-530’s memory, see Section 6.1.

2. Place Container 1 (full of parts) on the scale and press the + (Plus) key to store the total in Container 1.
The Acc (Accumulation) indicator lamp will now be illuminated. The display will show the total
quantity of pieces accumulated for 3 seconds, then return to the Normal Counting Mode screen.

This will also clear the accumulation register. The ACC (Accumulation) indicator lamp will no longer be
illuminated.

8. To clear the Unit Weight, remove all weight from the scale platter and press the C (Clear) key.

5.5.6 Normal Counting Mode - Negative Counting

There are two ways to do this depending on whether at the end you want to see the total amount remaining in the
container or the total amount removed from the container.

Scale Operations 29

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 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 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 TA RE 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

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 TA RE 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

TAR E 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 (
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.

Section 5.6) will cover operations in TEP Mode.

30 DC-530 Operation Manual

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. (Unlike in Normal
Counting Mode, the scale does not assume that the sample size is 10 pieces. You must enter the sample
quantity.) The scale will display the total Weight, Unit Weight, and number of Pieces and will indicate
that you have performed

SAMPLING 1 TIMES.

5. To improve the accuracy of the Unit Weight calculation, add another sample of the same pieces
according to the number indicated on the display (10 Pcs and below in the example above). Press the
PCS key. (If the Auto-Recomputing SPEC is set to 1: Auto, the scale will automatically begin
recomputing.)

As you add parts for the next sample, the scale display will indicate how many more pieces can be added
before reaching the maximum allowable for the resampling. If you add more pieces in the next sample
than the scale requests for its resampling, the scale display will turn red and the message

ITEMS

will appear, along with the number of items it suggests that you remove from the sample.

PLEASE REDUCE

If you add too few items for the scale to recompute the Unit Weight, the display will not change. Once
you add enough parts for another sample, the recomputing will take place. You can also gauge whether
your sample size is too small or too large by watching the bar graph at the bottom of the scale display. If
you add a sample and it does not register on the graph, it is too small. If you add a sample and the bar
graph goes all the way to the

MAX marker on the bottom right-hand side of the display you have exceeded

the maximum and need to remove some parts.

Scale Operations 31

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. If the Auto-Recomputing SPEC is not set to 1: Auto, you will need to press the PCS key
to recompute the Unit Weight after each sample is added. Repeat the procedure until the scale reads

SAMPLING 9 TIMES.

8. As you continue sampling, at the bottom of the display the DC-530 will show a bar graph of the Unit
Weight curve it is developing. After the ninth sample, the scale’s display will turn red indicating that the
sampling operation is complete.

9. Remove all the sample parts from the platter. The DC-530 will now calculate and display the maximum
Safe Quantity Limit that can be counted without error in the Limit field.

10. You can now begin counting operations by placing a quantity of the pieces to be counted on the

32 DC-530 Operation Manual

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.

If you press the TEP key to exit the TEP Mode after having established a Unit Weight and Safe Limit
Quantity, the scale will display the following message:

Enter 1 to clear the Safe Limit Quantity that you have established and go to Normal Counting Mode.
Enter 9 to keep the Safe Limit Quantity and stay in TEP Mode.

11. To clear the Unit Weight, remove all weight from the scale platter and press the C (Clear) key.

5.6.2 TEP Mode - Unit Weight Operation by Key Entry

Unit Weight operation by key entry is accomplished by using the numeric keypad to enter the known value of the
Unit Weight and then pressing the

UNIT WEIGHT key. An example of Unit Weight operation by key entry is

shown below:

1. Press the REZERO key to zero the scale.

2. With the display in the weighing mode, enter the known Unit Weight using the keyboard, for example,

200.00.

3. Press UNIT WEIGHT key to enter the Unit Weight.

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.

5.6.3 TEP Mode - Parts Counting

After you have established the Unit Weight of the part to be counted either by sampling (See Section 5.6.1
above) or by digital entry (See Section 5.6.2 above) and have entered a Tare Weight, you are ready to carry out
counting operations for that part. Alternatively, you can call up the data for an Item Code previously
programmed into the DC-530’s memory by entering the Item Code number and pressing the

# [CODE] key. If

you enter an Item Code for which the Safe Quantity Limit has not yet been established, you will see the
following error message.

If you receive this error message, you must use the scale to calculate the Safe Quantity Limit and edit the Item
Code record to include it. For more on how to establish the Safe Quantity Limit, see

Section 5.6.1.

1. The TEP Counting Mode display will show the maximum safe quantity of the part that can be counted

Scale Operations 33

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

6.0 Scale Programming

The DC-530 can store information for up to 200 of the parts you count most frequently, eliminating the need for
re-entering data during parts counting and greatly speeding up your counting operations.

6.1 Programming a New Item Code (Item Registration)

Before beginning to enter data about an item, you need to know the Tare Weight and the Setpoints you want to
set for this Item Code. If you are going to store a Tare Weight, it must be known in advance because it cannot be
established from the scale platform during Item Registration mode, it must be entered digitally.

When programming the DC-530, you can use the following functions of its keyboard.

Key Function

To move the cursor to the next field without changing the value of the current field or to move to the
next field in Edit Item Mode after entering new data.

To move the cursor back to the previous field without changing the value of the current field.

To save the data entered and exit the Programming Mode. You will be prompted to confirm
whether or not you want to save any changes you have made to the data.

To exit the Programming Mode without saving the data entered.

This section details the procedure for storing the Unit Weight, Tare Weight, and Set Points to be associated with
an Item Code. You can enter all of this information for each Item Code or only the data pertinent to your
application. You can enter the Programming mode from either the Normal Counting Mode or the TEP Mode.

1. First establish a Unit Weight for the item by either a sampling process or manual entry and press the
UNIT WEIGHT key. (See Section 5.5 or Section 5.6). This will bring you to the Item Programming
screen. The upper right hand corner of the screen will show you how many of the 200 Item Codes the
DC-530’s can store have already been programmed.

2. Enter the three-digit Item Code for the item you want to store in memory and press the # key. The Item
Code will appear in the upper left of the Item Screen. The cursor will then move to the next field which
is entering the Tare Weight (The Unit Weight will have been already recorded by the scale from the
sampling operation or digital entry of the Unit Weight. If you started from the TEP Mode, the Limit
field will also have been automatically filled in).

Scale Programming 37

If you enter an Item Code that has already been programmed, the display will flash red and the error
message

ITEM XXX, EXISTING ITEM will appear. Then the screen will ask you if you are trying to update the

data associated with this item already existing in memory.

If you enter a 1 from the numeric keypad the screen will flash red and show the message:

You will then be returned to whichever Counting Mode screen you began with - Normal Counting Mode
or TEP Mode.

If you enter a 9 from the numeric keypad to indicate you do not want to take the data you are entering
and associate it with the Item Code already in memory, you will be returned to the Item Registration
screen where you can enter a new Item Code to save the data under.

3. Enter the tare digitally using the numeric keypad. The Tare Weight value must be entered without a
decimal point. The Weight field is 5 digits long and the placement of the decimal point is determined by
Bits 2, 1, and 0 of Specification 21 - Weight Decimal Point Position. The digits you enter for the tare
weight will fill the field starting from the right. (Example: if the decimal point is set as 0.0000 and you
enter the digits 125, the net weight will show as 0.0125.) Note that you cannot establish the Tare Weight
from the scale during Item Registration mode, it must be entered manually.

Press the + (Plus) key. The cursor will move to the field for Set Point 1.

4. You cannot edit the Scale Number field in Item Registration mode. The DC-530 will automatically set
the Scale Number field to the scale the item sample was taken on. The Scale Number field can be edited
in the Edit Item mode (See

Section 6.2.3).

5. If Specification 01 Bits 3 and 2 are set to 00:No Operation or 01:Common Set Point then setpoints
cannot be entered for an individual Item Code here. If Bits 3 and 2 are set to 10: Item Set Point, then the
cursor will move to the field for Setpoint 1. Remember that Specification 02, Bit 2 - Setpoint Selection
sets whether the setpoint is programmed on the basis of pieces or weight. The default is 0: Pieces. Enter
a quantity for Setpoint 1 and press the + (Plus) key to move to Setpoint 2. Repeat for Setpoints 2 and 3.

6. When you have finished entering the data for this Item Code, press the * PRINT key to save it. The
display will confirm that the scale is saving the new Item Code to memory and then return you to
whichever Counting Mode screen you began with - Normal Counting Mode or TEP Mode..

6.4 Setting a General Setpoint

User Specifications 01 and 02 set the parameters of the DC-530’s use of any setpoints that are programmed.

User Specification 01, Bits 3 and 2 - Set Point Operation, establish whether setpoints will be associated with
individual Item Codes or be general or common setpoints applied to all items. The specification can also be set
to not allow any setpoints to be programmed.

• If Specification 01, Bits 3 and 2 are set to 10: Item Set Point, the setpoints must be programmed in

the Item Registration or Item Edit procedures (See Section 6.1 or Section 6.2). In this case Option 4
on the Mode Menu - Set Point Setting is disabled.

• If Specification 01, Bits 3 and 2 are set to 01: Common Set Point, the setpoints must be programmed

in the Set Point Setting screen as described below and the cursor will not move to the Setpoint fields
in the Item Registration and Edit Item modes.

• If Specification 01, Bits 3 and 2 are set to 00: No Operation, Option 4 on the Mode Menu - Set Point

Setting, is disabled and the cursor will not move to the Setpoint fields in the Item Registration and
Edit Item modes.

User Specification 02 sets the rest of the parameters of the DC-530’s use of the setpoints programmed:

• Specification 02, Bit 0 - Setpoint Range, sets whether the range is negative or positive. The default

is 1: Positive. If set to 0: Negative, the buzzer only sounds on negative numbers.

• Specification 02, Bit 1 - Setpoint Buzzer Output, sets whether the scale sounds an audible buzzer

when a setpoint is reached. The default is 1: Yes.

44 DC-530 Operation Manual

• Specification 02, Bit 2 - Setpoint Selection, sets whether the setpoint is programmed on the basis of
pieces or weight. The default is 0: Pieces.

• Specification 02, Bit 3 - Buzzer Output Type, sets whether the buzzer sounds as “Proper” or “Scare/
Over”. The default is 0: Proper. (Example: If the Buzzer Output Type is set to 0: Proper and you
have set point values of 50, 75, and 100, a fast beep will sound at 75 and turn off when you reach

100. If Buzzer Output Type is set to 1:Scare/Over, and you have the same set point values of 50, 75,
and 100, a slow beep will begin at 50 and stop when you reach 75. When you reach 100 there will be
a fast beep.)

1. While in the Counting Mode screen (either Normal Counting Mode or TEP Mode) press the MODE key

to go to the Mode Menu screen.

2. In the Mode Menu screen, press 4 to enter the Set Point Setting screen.

(NOTE: If Specification 01 Bits 3 and 2 are set to 10: Item Set Point or 00: No Operation, this menu option is disabled.)

General Data Format

All data values are in ASCII format.

ID Code

The ID Code data string is 12 digits.

Set Points

Item Set Points are transmitted when an Item Code is recalled from memory. When no Item Code has been
recalled from memory, General Set Point data is transmitted. The type of setpoint is determined by the header
code of Setpoint 1. When the output is set to include Header Codes, an “F” header indicates a weight setpoint
while a “G” header indicates a quantity setpoint. When the output is set to include Titles instead of Header
Codes, a “Q” title will indicate a quantity setpoint and a “W” title will indicate a weight setpoint. Setpoint data
can consist of either 7 digits or 6 digits plus a decimal point.

Weight Variables

Gross Weight, Unit Weight, Tare Weight, and Net Weight data can be either 7 digits or 6 digits plus a decimal
point.

Quantity Variables

Total Quantity and Quantity data can consist of up to 6 digits, with a range between -99999 and 999999.

Date and Time Variables

The data string for Date and Time variables is ordered as follows:

7.4 Setpoint Connector

Your DC-530 has a setpoint output that can be attached to output relays for setpoint control of external
equipment when setpoint conditions are satisfied. The device receiving the signal is connected to the DC-530’s
Setpoint Connector (see

Figure 7-1).

To set up the DC-530 to output when the setpoint conditions are satisfied, program the customer specifications as
detailed in

Section 6.4.

7.5 Bar Code Scanner

A laser scanner allows for instantaneous and accurate input of basic data for an item. The DC-530 has bar code
scanning capabilities by plugging the optional QS-6000 Bar Code Scanner (Part No. 65619) into the RS232C-1
port on the scale (see
Tare Weight, and the Item Code. In the Programming Mode you can scan in the Part Code, Unit Weight, Tare
Weight, and Setpoints.

To setup the necessary specifications for bar code scanning, set the DC-530’s specifications as follows:

• SPEC 04 - Bar Code Scanner to 0010

• SPEC 06 - RS232C Output to 1001

• SPEC 07 - RS232C1 Baud Rate to 0100

• SPEC 08 - RS232C2 Parity/Bit/Stop Bit/Data Length to 0000

• SPEC 55 - Scan Quantity Type must be set for either Item Quantity (the default) or Accumulation
Quantity.

7.6.1 Setting the Specifications for Scale 2

A scale connected to the Remote Scale Channel will be recognized by the DC-530 as Scale 2. The specifications
that need to be set to configure the communication with the second scale are as follows:

• SPEC 14, Bit 1 - Auto Scale Switching sets whether or not a Unit Weight established on the built-in
platform is automatically transferred to Scale 2. When Auto Scale Switching is enabled, the scale
also automatically switches to Scale 2 once a stable Unit Weight is calculated.

• SPEC 14, Bit 2 - Rezero When Swap Scale sets whether the scale is rezeroed automatically when the
SCALE key is pressed to move from weighing on one scale to weighing on the other

• SPEC 14, Bit 3 - Clear Unit Weight When Swap Scale sets whether the Unit Weight is cleared
automatically when the SCALE key is pressed to move from weighing on one scale to weighing on
the other.

• SPEC 21, Bits 1 and 0 - Minimum Display (Scale 2) sets the display divisions displayed for Scale 2.

• SPEC 24 - Selection of Resolution of 2nd Scale (Scale 2) sets the display resolution for Scale 2.

• SPEC 25, Bits 2 through 0 - Weight Decimal Point Position of 2nd Scale (Scale 2) sets which digit
the decimal point appears after in the Weight display.

• SPEC 26, Bit 1 - 2nd Scale sets whether or not the Remote Scale Channel is enabled. Please note
that the scale switch is not activated until the 2nd scale has been calibrated.

• SPEC 30 - Set the Tare and Unit Weight Auto Clear conditions.

• SPEC 34 - Loadcell Sensitivities Selection mV/V (2nd Scale) sets the loadcell sensitivity range for
Scale 2.

• SPEC 35, Bit 2 - 2nd Scale Weight Unit sets whether the basic weight units for Scale 2 will be lbs or
kgs.

For information on how to set the above User and Weight and Measurement specifications, see Section 3.0.

The scale was started while something was
on the platter and the weight was unstable.

The REZERO key was pressed while
something was on the platter and and the
weight was unstable.

The Unit Weight in use is too light (smaller
than the light range) for an accurate counting
operation.

You are trying to recall an Item Code from
