    BASIC WEIGHING To weigh a sample on your scale, use the following procedure: 1. Press the zero key. 2. Place the object(s) to be weighed on the pan. 3. Wait for the “OK” symbol, then read the weight from the display. WEIGHING WITH THE TARE FUNCTION To weigh objects (or liquids) in a container without including the weight of the container, use the tare function.

  • Page 14: Net Totalizing By Weight

    6. Press the gross key. 7. Wait for the “OK” symbol, then read the gross weight from the display. Note: Pressing the gross key adds the tare (container) weight to the net (contents) weight to provide the gross (combined) weight. Pressing the gross key again ( or pressing clear ) will return the display to net weight.

  • Page 15: Basic Counting

    BASIC COUNTING To count the number of like objects placed on your scale, use the following proce- dure: 1. Press the zero key. 2. Place a known number of pieces on the pan. 3. Enter the number of pieces you have placed on the pan. 4.

  • Page 16: Counting With The Gross Function

    COUNTING WITH THE GROSS FUNCTION You can use your scale to count the number of pieces being placed in a container, find the net weight of the pieces, and find the gross (combined) weight of the pieces and the container. To do so, use the following procedure: 1.

  • Page 17: Counting With Accuracy Enhancement

    COUNTING WITH ACCURACY ENHANCEMENT When counting parts that are not uniform in weight, you can periodically update the average piece weight (APW) and thereby increase the accuracy. Each time the count key is pressed, the scale will update the APW as long as the additional weight is less than or equal to the previous sample weight.

  • Page 18: Net Totalized Counting

    6. Remove pieces until the display reads the number of parts you wish to count out or kit. 7. Press the zero key. 8. Repeat Steps 6 and 7 as many times as needed. Note: If the average piece weight (APW) is known, you may press the — key, enter the APW, and press the apw key in place of Steps 3, 4, and 5.

  • Page 19: Using The Minimum Sample Size Feature

    USING THE MINIMUM SAMPLE SIZE FEATURE Similar looking pieces often may vary in weight, so it is necessary to use a “signifi- cant” sample size when using your scale to count pieces. To count when your scale has been setup to require a minimum sample size (see Appendix II), use the following procedure: 1.

  • Page 20: Accumulating Results

    minimum weight necessary has been placed on the scale, it will instruct you to add the necessary number of pieces to the pan. To count, continue by following Steps 6-8. 6. Add the exact number of pieces requested by the scale. 7.

    6. Press the accum key. 7. Press the count key and remove the pieces. 8. Repeat Steps 1-7 (or Steps 5-7 for pieces from the same lot) anytime you wish to add to the accumulated count. 9. Press the ./rcl key. 10.

  • Page 22: Printing Out Information

    PRINTING OUT INFORMATION Your Setra scale is designed to print out requested or available information regard- ing a given batch when connected to a Setra Model 240P or 340P printer (see Appendix II). To print, use the following procedure: 1. Connect the printer’s AC adaptor to a 110-volt outlet. 2.

  • Page 23: Section Four

    Section Four Dual Scale Operation Dual platform, or dual scale, operations yield excellent counting accuracy for large counts using small sample sizes. It involves connecting two Setra scales together, sampling on one scale, and bulk counting on the other. The lighter capacity scale calculates the average piece weight using a very small sample size.

  • Page 24: Using A Dual Scale System

    higher capacity scale must be in the normal mode (see Step #5 above). (Contact your Authorized Setra Dealer or the factory for more cabling information.) The dual scale system is now set up. Test the system by following the procedure below.

  • Page 25: User-Definable Units

    Appendix I User-Definable Units USER-DEFINABLE UNITS User-definable units are units of measure whose conversion factors are determined by the user. Setra scales have two user-definable units of measure: X and T units. These units may be used to weigh in dollars (given the weight of one dollar of substance), length (given the weight of a known length of material), or volume (given the weight of a known volume of material).

  • Page 26: T Units

    T UNITS T units are tamperproof user-definable units which are indirectly changed by enter- ing a factor or divisor. To change T units, proceed as follows: 1. Calculate the ratio you wish to enter. If your ratio is in grams per T unit, ounces per T unit, etc., you will enter a divisor.

  • Page 27: Setup Functions

    Appendix II Setup Functions PRINT FORMAT The print format function controls the printout of various measured and stored numbers. To format which functions are to be printed, use the following procedure: 1. Press the — key and enter 1111. 2. Press the setup/cal key. The display will read "CAL Pr." 3.

  • Page 28: Formatting Minimum Sample Size

    Note: Your printer is now formatted. To change the print format, simply repeat Steps 1-15 above. The factory default setting prints out all known and available information. If an I.D. number has been entered, it will always print. When connected to a computer, if all print formats have been selected to be off (0), the scale will output "string format"...

    higher). The scale will return to the normal weighing mode and the bar code print mode may be accessed by pressing the ./rcl and print keys. 4. Press the setup/cal key. Press clear if you do not wish to proceed. 5.

  • Page 30: Dual Scale Operation

    DUAL SCALE OPERATION The dual scale system involves connecting two Setra counting scales to achieve accurate bulk counts using small sample sizes. Dual scale operation is described in Section Four. For dual scale operation, follow this procedure for the sampling scale only: 1.

  • Page 31: Restoring The Factory Default Setups

    RESTORING THE FACTORY DEFAULT SETUPS The many features described in this section allow the user to customize the scale to suit a particular application. However, in doing this it is also possible to inadvertently setup the scale in such a way that it will not operate as expected. To reset the scale to the original factory defaults, follow the steps outlined below.

  • Page 32: Altering Display Update Rate

    ALTERING DISPLAY UPDATE RATE The INT Mode is factory preset to provide a fast display update (short integration time) for filling parts to a target count/weight. The use of this mode can be altered to provide a slow display update (long integration time) for weighing in the presence of draft or vibration.

  • Page 33: Calibration

    Appendix III Calibration Your Setra scale may be calibrated as often as desired. The scale should be span calibrated prior to initial use to correct for differences in gravity between your location and the factory. FULL SCALE SPAN CALIBRATION To calibrate your scale with a full scale weight (available from your dealer), use the following procedure: 1.

  • Page 34: Typical Uses Of Your Scale: Examples

    Appendix IV Typical Uses of Y our Scale: Examples Taring Out Box Weight Before Weighing Widgets Suppose you wish to fill an empty box with widgets and find the weight of the widgets in the box, not including the weight of the box. Using the tare function of your scale, you would place the empty box on the pan, tare out the box weight, and then load the widgets into the box.

  • Page 39: Sending Alphanumeric Id#S To The Scale

    Never include a carriage return or line feed in any command sequence. The scale uses any command character as a terminator for an input string. For example, if you wish to enter a tare weight of 1000 (in the units currently being displayed), simply send “1000T”.

  • Page 40: Receiving Data From The Scale

    Receiving Data From the Scale The print or output format for the scale is user selectable. When a scale is connected to a computer, it is suggested that "string format" be used. (This is selected through the Print Format setup function described in Appendix II.) When this format is selected, the scale will transmit whatever number or message appears on the scale display upon request.

  • Page 41: Immediate And Continuous Print Modes

    “c3” is the “stability” character. When a “ “ (space) is transmitted, the reading is not stable. When an “S” is transmitted, the reading is stable. This corresponds to the “ok” symbol on the display. The string format output is always transmitted with a carriage return and line feed. The following are some examples of string format output: “_ _ _12.3_GPS”...

  • Page 42: The Jump Function

    In the continuous print mode, any messages that appear in the display, including error messages such as "UnAbLE", will be transmitted over the RS-232. The continuous print mode always transmits "string format," regardless of which print format is selected. Note: When using the continuous print mode, it is recommended that the baud rate be set at 2400 or higher to ensure that the all scale output can be transmitted.

  • Page 43: The Verify Function

    The Verify Function When many scales or other peripherals are connected to a computer, it is sometimes useful for the computer to be able to check on the status of these devices. The verify function can be used to determine the model number of a scale and determine that the scale is functioning properly.
  • Page 44 DESCRIPTION Protective Ground Scale Receives Data Scale Transmits Data Protective Ground It is necessary for the receive data pin of the external device to be connected to pin 3 (transmit data pin) of the scale. Likewise, the transmit data pin of the external device must be connected to the receive data pin (pin 2) of the scale.
