Introduction Thank you for purchasing a Setra Quick Count scale. Its ease of operation and durable construction should provide years of convenient and reliable service. While your scale is easy to operate, it is advisable to read this manual carefully before use. It is designed to help you perform weighing, counting, and related operations quickly and accurately. This manual is divided into four sections. Section One, “ Installing Your Scale,” explains the proper installation of your scale.

Components and features of the Setra Quick Count.
Section One Installing Your Scale SETUP 1. Locating your scale The rugged design of your Setra Quick Count scale ensures that it will operate well in typical factory or office environments. Nonetheless, you should treat your scale as you would any piece of precision equipment, locating it on a clean, dry surface; protected, where possible, from extremes of draft and vibration. 2. Leveling your scale a. Retract the right rear foot completely into the scale. b.
power up the scale. The scale draws very little current from an outlet and may be left connected. This keeps your scale ready to use with no “ warm-up” time.
EXPERIMENTATION 1. Display test When your scale is first powered on, it automatically runs through a display test; lasting about six seconds. The scale next displays “ C nnn g” where nnn equals the full scale capacity in grams), performs self-diagnostics to ensure proper operation and then sets itself to zero. A wake up message is always transmitted upon power up. (If a printer is connected to the scale, the scale model, capacity and software version will be printed.
Section Two Understanding Your Scale KEYBOARD FUNCTIONS zero sample size Assigns the pan and whatever is currently being weighed a value of zero. While the scale is determining a stable zero reading, the display will indicate “ bUSY” . Displays pieces). preprogrammed sample sizes (10, 25, 50 or 100 count Instructs the scale to begin or resume counting. This key may also be used to “ update” the average piece weight for increased counting accuracy.
DISPLAY The weight on the pan exceeds the capacity of the scale; the pan is not properly seated or the scale is under loaded. OFLO The displayed count exceeds six digits (999,999). UPdAtE The scale is recalculating the average piece weight to enhance counting accuracy. Add nnn.PC The scale is requesting an additional number of pieces (nnn) to satisfy any minimum accuracy setup requirements. Sub nnn.
Section Three Using Your Scale 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. CONVERTING THE WEIGHING UNITS Your Quick Count scale is capable of weighing in any of the units listed in the DISPLAY SYMBOLS portion of this guide. To convert from one unit to another, simply press the units key.
BASIC COUNTING USING THE SAMPLE SIZE KEY To count a number of like objects on the scale, use the following procedure: zero sample count size print clear 0.00 g 1. Place an empty container on the scale. Press the zero key. -----------------------------------------------------------------------zero sample count size print clear Add 10 Pc 2. Press the sample size key. Each time the key is pressed the requested sample size will increase (i.e., Add 10, 25, 50, 100 PCs).
USING THE MINIMUM SAMPLE SIZE AND MINIMUM ACCURACY FEATURE Counting errors can be caused by non-uniformity in the parts being counted or by insufficient sample weight. To reduce these errors your scale has been designed with two special features. The minimum sample size feature ensures that the scale will calculate an average piece weight from a large enough sample which is nearly equal to the average piece weight of the entire lot.
NOTE: The accuracy enhancement feature is disabled if the average piece weight has been scanned in from a bar code or entered via a computer.
REVERSE COUNTING OR KITTING Using this feature, you can place a container full of pieces on your scale and count the number of pieces removed. This is especially helpful when kitting (counting out a certain number of pieces to be packed together). To perform reverse counting or kitting, use the following procedure: 1. Place a container full of pieces you wish to count on the pan. 2. Press the zero key. 3. Press the sample size key. 4. The scale display will say “ Add 10. PC” .
PRINTING OUT INFORMATION Your Setra Quick Count scale is designed to print out requested or stored information regarding a given batch when connected to an optional serial printer (see Appendix I). To print out information using the Setra Model 240P or 340P dot matrix printer, use the following procedure: 1. Connect the printer’s AC adaptor to a 110-volt outlet. 2. Connect the other end of the adaptor to the printer. 3. Connect the appropriate end of the printer connection cord to the printer. 4.
Appendix I Set-Up Functions Your Setra Quick Count scale was programmed at the factory to operate in a prescribed manner. Many of the factory settings can be altered by an authorized Setra dealer to optimize scale performance for your counting or weighing operation. For example, the scale is factory preset to request a minimum of 10 pieces to initiate the counting process. Your dealer can alter the minimum to a smaller or larger sample, such as 5 or 25 pieces.
Appendix II Calibration Your Setra Quick Count scale is highly stable, and requires infrequent calibration. While it may be span calibrated as often as desired, the factory calibration is adequate for most counting applications. For precise weighing applications more periodic calibrations may be desirable. To perform a span calibration on Quick Count scales with operating program version 1.3 or higher, use the following procedure: 1. Remove all objects from the pan. 2. Make certain the scale is level. 3.
Appendix III Glossary of Terms ACCURACY The degree of conformity of a measured value to the true value. AVERAGE PIECE WEIGHT The average weight in a sample of like pieces. BAUD RATE The rate at which your scale transmits or receives information to or from a computer or peripheral device. DISPLAY HYSTERESIS The tendency of a scale with a fluctuating reading to stabilize on the higher value. KITTING Repeatedly removing a given number of pieces for inclusion in a kit; e.g.
Appendix IV RS-232 Serial Data Communications Your Setra Quick Count comes equipped with a bidirectional RS-232 interface using a default baud rate of 2400 and no parity. Users who have purchased a Setra 240P or 340P printer may simply follow the directions under “ Printing Out Information” to connect it to the scale.
For further information, obtain a copy of the Setra Quick Count Technician's Guide by contacting your local authorized Setra dealer.
Appendix V Accessories and Options The following accessories are available for the Setra Quick Count. Ask your dealer for current price information and/or a demonstration. Part Number Description 401150 240P PRINTER - 40 column dot matrix tape printer comes preinterfaced to Setra scales and balances. Printer has an RS232 serial asynchronous interface with 1.5 kilobyte data buffer and user selectable baud rate. Printing is bidirectional at 2 lines per second, and baud rate is selectable.
Appendix VI In Case of Difficulty Setra Quick Count scales are designed to be easy to use. If, however, you have reached a state in which the scale will no longer follow your instructions, you may wish to “ reset” the scale. It is possible to do so by following this sequence. 1. Remove all weights from the pan. 2. Press the clear key. 3. Press the zero key. If this procedure does not solve the problem, try briefly unplugging the unit from its power source then plug the unit in again.
If the scale displays “ d-noS” , it may have been subjected to an extreme discharge of static electricity or power line fluctuations. The scale can be easily restored to operation by following the procedures outlined in steps #4 and #5 above. Note, the user setups will be restored to the original factory defaults. If the RS-232 interface does not function correctly, first make certain that you are using the correct RS-232 cable, and that it is securely fastened to both the scale and the peripheral device.
Appendix VII Battery Option INSTALLATION Disassembly of the entire scale is not required when installing the battery option kit. 1. Position the back of the scale so it overhangs the rear of a work bench (see Figure 2). 2. Remove the (2) Phillips head screws (marked “ A” the rear panel. in Figure 2) and 3. Next remove the (2) hex head screws and washers marked “ D” Figure 2. in 4. Disconnect the ribbon cable and remove the power circuit board. 5.
BATTERY USE FOR PORTABLE SCALE OPERATION A fully charged battery will allow a Setra scale to operate for approximately 24 hours before recharging is needed. The battery will last one-half as long or about 12 hours if the scale is equipped with an Auto Count 200. The “ low bat” indicating light on the front panel of the scale will light up approximately one hour before recharging is necessary.
