DS-470 OPERATING MANUAL 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.
2.0. SPECIFICATIONS This section includes a detailed listing of all pertinent specifications and parameters for each of the DS-470 weighing scales. The system weighing accuracy is 0.02 % for all models and they meet or exceed the requirements of OIML, Class III, and NIST Handbook, Number 44. Â 2.
2.2. Physical Dimensions 2.3. Color LED Bar Graph LEDs provide clear indication of weight condition between minimum and maximum besides the digital weight display. 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.
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.

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.

6.1.4. COMMUNICATION METHOD By specification setting (Spec 59 bit 2 & 3), the communication method may be selected from Stream (continuous output), Manual (output by pressing [½ ½] key, and Command (output by command from external device). 6.1.4.1. STREAM Data is transmitted to external device continuously. DATA STREAM: The SPEC to select whether weight stable status or not by specification setting (Spec 53 bit 3).
6.1.4.2. MANUAL Data is output by pressing [½ ½] 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. 6.1.4.2.1. MANUAL (METHOD 1) DATA FORMAT: Example: By pressing [½ ½] key.
6.1.4.2.2.
6.1.4.3. COMMAND Data is transmitted by receiving ENQ from external device. By specification setting (Spec 59, Bit 1), it is to select to transmit the data right away or to hold the command until weight becomes stable. If weight is not back to stable within a certain interval (by specification setting Spec 59 bit 0), TIME OUT ERROR will appear on the display.
6.2. Transmit Set-Point Data 6.0.1. Transmit Set-Point Data From External Device If Set-point data from an external device spec(spec 53 bit 2) is enabled and when MAX key is pressed without entering numeric data I Operation mode, the scale would send ENQ data and the external device would send the set-point data back.
6.0.2. Transmit Set-Point Data To External Device If Set-point data to an external device spec (spec 53 bit 2 ) is enabled and when MAX key or MIN key is pressed in the in Operation mode, the scale would send DC2 or DC4 and the external device would receive the set-point data.
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.
7.1.3 Continued 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. 7.2.
