1.0. GENERAL
1.1. Features
The DS-470SS Check Weighing Scale offers a practical solution to a wide
range of weighing applications. There are a variety of weight capacities and
increments available. The display resolution is selectable from 1/3,000 to
1/15,000. It features keyboard calibration with auto-span and ON/OFF,
REZERO, TARE, for one touch tare and a numeric keyboard for digital tare
and set point entry. For a list of platform sizes and available capacities see
page 2.
This instruction manual will provide the user with all the information necessary
to understand, set-up and operate the DS-470 scale. Included in this manual
are descriptions, specifications, drawings, and operating instructions.

Target range is determined by entering 2 set points (min and max range.) The value can be
entered by any method described in section (5.6.) on pages 13 - 15. Set points alert the operator
with both auditory and visual signals if weight is within the target range.
The graduation of LED is determined by dividing the target range by 5 (Max weight – Min weight /5)

3.0. INSTALLATION
This section provides the information required for installation of the DS-470 weight
indicator.
The following steps accomplish installation.
1. Unpacking
2. Set-up Procedure
3.1. Unpacking
Each component of the DS-470 is packed in a specially designed carton.
Remove each component from its carton, separate the component from its
polystyrene shell assembly and set aside. Inspect the carton interior to be
sure that all accessories have been removed from the carton. Inspect the
carton inner panels for accessories.
NOTE: Be sure to repack all materials within the carton set. Store the
cartons in a secure area so they can be available whenever shipment of the
scale is required.
3.2. Inspection
Immediately after unpacking, a visual inspection of the instrument should be
performed. If any damage has been incurred during transportation the
shipper and DIGI MATEX INC. should be notified immediately. Instructions
for assessment of damage and further procedures will then be determined.
3.3. Repackaging
If, at anytime, the DS-470 check weighing scale must be returned for
modification, calibration, or repair, be sure that it is properly packed with
sufficient cushioning materials.
Whenever possible, the original carton assembly should be retained for this
purpose. Any damage caused by improper packaging will not be covered by
warranty.
3.4. RS – 232 Cable Installation & Assembly
The DS-470 has RS-232 & set points as a standard feature and are spec
selectable, pole mounting kit comes with all the necessary hardware and
assembly is easy. See page 6 for details.
3.5. DS-470 SS Unlocking
The unlocking procedure is Included on page 6.

4.0. ELECTRICAL TEST
4.1. Set-Up Procedure
This part of the procedure is used to verify proper operation of the weighing scale.
Place the scale on a reasonably level surface. Level the scale using the adjustable
legs and the level bubble guide.
Connect the AC power source, and press the "ON/OFF " key, the display will
momentarily show all digits from 0 to 9 in a "count-up" mode. Then the display will
blank, show all "8's", and enter the regular operating display.
If at any time the scale displays erratic data, it may be caused by a power transient.
Turn the scale "off" and momentarily unplug it from the wall outlet. Then restart, by
plugging the scale back in and pressing the "ON/OFF " key.
4.2. Keyboard and Display Test
This part of the procedure is used to verify proper operation of the various switches
and displays.
The following functions will be tested in this procedure:
A. Re-Zero
A. Tare Entry
B. Digital Tare Entry
4.2.2. One Touch Tare
A. Press the "0" key and then the "TARE" key to reset any Tare.
B. Press “REZERO” key to re-zero the scale.
C. Place the empty container on the scale and press the "TARE" key
once. The weight display should now read zero with the empty container
on the scale.
4.2.3. Digital Tare Entry
A Press the "TARE" key.
B Press the "RE-ZERO" key. After resetting, the Displays will read zero.
C Enter the number 0.2 by using the keyboard. Then press the "TARE" key.
D The weight display will show the weight entered with a negative sign
indicating that the weight displayed is a Tare Weight.

6.1.4.2. MANUAL
Data is output by pressing [½½½½] key. User may select to transmit the data right away
or to hold the command until weight becomes stable (from Spec 59 bit 1). If weight
is not back to stable within a certain interval (from Spec 59 bit 0), TIME OUT ERROR
will appear on the display. The two communication methods may be selected in this
mode.

7.0. MAINTENANCE, CALIBRATION, TEST PROCEDURE & SERVICE
This section contains information and instructions concerning maintenance of the
DS-470 check weighing scale.
Preventive maintenance consists of periodically cleaning the external surfaces of
the instrument and should be performed as often as operating conditions warrant.
The calibration procedure is designed to be an aid in maintaining the scale accuracy
within specifications. The calibration procedure may also serve as a performance
test procedure.
CAUTION: DO NOT ATTEMPT ANY SERVICE WHILE THE INSTRUMENT IS
CONNECTED TO THE POWER LINES.
7.1. Maintenance Procedures
7.1.1. Exterior Maintenance
The exterior surfaces of the counting scale can be easily cleaned using
soap and water. However, extreme caution should be used so that there is
no possibility of water penetration into the scale electrical or mechanical
sections. A damp cloth or sponge is suggested. NEVER USE ACETONE,
MEK, OR SIMILAR SOLVENTS ON THE PLASTIC HOUSING AS THEY
WILL ETCH THESE SURFACES.
For grease or other difficult spots, a chlorothane or naptha based cleaner
may be used. Never use any solvents on the front or rear panels.
Accumulations of dust or direct particles between the pins of the
connectors may be removed by using dry forced air or a small dry brush.
7.1.2. Internal Maintenance
Internal maintenance is not normally required and if it is, should not be
attempted except by a qualified, authorized service technician.
7.1.3. Calibration
The following procedure should be followed periodically (every six to
twelve months is suggested) to determine that the scale is functioning in all
modes.
a. Electrical
Follow section 4.0 through all its steps
21
7.1.3 Continued
7.2. Service & Repair
No service or repair should be attempted except by qualified personnel, and
not until it has been positively determined that the counting scale requires
such service. All service should be done in a clean, dry, dust-proof area.
b. Accuracy
Weighing: The scale weighing accuracy can be determined by
applying various known weights to the platform. Because of the
scale's very high accuracy, only weights that are certifiably more
accurate than the scale's specifications should be used in testing
for accuracy. (NBS class "F" or higher)
Since the scale owner does not normally have such certifiable
weights available to him, it is suggested that the customer call
their authorized
DIGI dealer.
