OFLO The display is overloaded during counting. Remove some of the pieces, and weigh or count in smaller lots. FLASHING The weight on the pan exceeds the capacity of the scale. -
Page 9: Section Three
Section Three Using Y our Scale ENTERING A NUMBER OR FUNCTION To enter a number or function on your scale, simply press the key or keys which correspond to the numbers or functions you wish to enter. No key is necessary to request the weighing function, as it is automatically displayed when the scale is plugged in and something is placed on the pan. -
Page 10: Basic Weighing
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 11: 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 the net weight. -
Page 12: 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 13: 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 14: 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 15: 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 16: 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 17: 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. -
Page 18: Assigning An I.d. Number To A Batch
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 19: 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 adapter to a 110-volt outlet. 2. -
Page 20: 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 21: 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 22: 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 23: 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 24: 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 25: 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 27: 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 28: 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 29: 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 30: 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 31: 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 32 average weight of one microchip. Next you would press the apw key. You would then remove microchips until the scale reads 25. You would re-zero the scale and repeat the process until the desired number of kits has been completed. Counting Nonuniform Ball Bearings with Accuracy Enhancement Suppose you wish to accurately count nonuniform ball bearings using a small sample size.

Page 33: Glossary Of Terms
Appendix V Glossar y of Terms ACCURACY The degree of conformity of a measured value to the true value. AVERAGE PIECE WEIGHT The mean weight in a sample of like pieces; e.g., washers. BAUD RATE The rate at which your scale transmits or receives information to or from a computer or peripheral device. -
Page 34: Rs-232 Serial Data Communications
Appendix VI RS-232 Serial Data Communications Setra scales come equipped with a bidirectional RS-232 interface. Users who have purchased a Setra 240P or 340P printer may simply follow the directions under “Printing Out Information” in order to connect the scale with that unit. Users who are interfacing a scale to the Setra Auto Count 200 System should follow the installation instructions in the operator’s manual for that equipment. -

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 36: Receiving Data From The Scale
To enter an ID# from a computer, send the following string to the scale: / [string identifier] $S The ID START (or introducer), “/”, instructs the scale to ignore subsequent charac- ters as commands. The ID FINISH (or terminator), “$”, instructs the scale to interpret subsequent characters as commands. - Page 37 “c1” is the “mode” character. It describes what the number being transmitted represents. The following is a list of all possible characters sent in this digit: CHARACTER MEANING (space) Number field is a reading or message Reading is in the INT mode Number field represents GROSS weight Number field represents TARE weight Number field represents APW...

Page 38: Immediate And Continuous Print Modes
Immediate and Continuous Print Modes Two types of output modes are available on Setra scales - immediate and continuous print modes. The immediate print mode is enabled by transmitting a "P" over the RS-232 or by pressing print on the keypad when "string format" is selected. In this mode, the contents of the display are transmitted. -
Page 39: The Jump Function
To enable the verify function, transmit an ASCII "V". If the scale is functioning properly, a scale will send one of the following messages followed by carriage return and line feed: "Setra 12000C" "Setra 5000C" "Setra 2000C" "Setra 500C"... -
Page 40: Status After Power Is Applied
Status After Power is Applied All Setra scales have an internal nonvolatile memory for storing certain status informa- tion. This memory is not erased when the scale is powered down. All setup functions (such as print format, minimum pieces, minimum accuracy, baud rate, and tone enable/ disable) and user conversion factors are stored in this memory. - Page 41 Note: The "handshake" signals, such as "busy", are not implemented. This requires that the peripheral have a minimal buffer (15 characters). Some computers requiring handshaking will need a connection between two pins on the computer’s connector named DTR and DSR (Data Terminal Ready and Data Set Ready).
