Page 3: Introduction
Introduction Thank you for purchasing a Setra Easy Count scale. Its ease of operation and durable construction should provide years of convenient and reliable ser- vice. While your scale is easy to operate, it is advisable to read this manual carefully before use. -
Page 4: Section One
Section One Installing Your Scale SETUP 1. Locating your scale... You should treat your scale as you would any piece of precision equip- ment, locating it on a clean, dry surface; away from extremes of draft and vibration. 2. Leveling your scale... The bubble level is located underneath the loading pan. -
Page 5: Experimentation
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. -
Page 6: Section Two
Section Two Understanding Your Scale KEYBOARD FUNCTIONS EZ6: zero Assigns the pan and whatever is currently being weighed or counted a value of zero. While the scale is determining a stable zero reading, the display will indicate “bUSY”. sample size Displays the preprogrammed sample sizes (10, 25, 50 or 100 pieces). -
Page 7: Display Symbols
DISPLAY SYMBOLS EZ2/EZ6: Reading shown is stable. Reading shown is given in number of pieces. Reading shown is given in grams. EZ6: Reading shown is given in ounces. Reading shown is given in pounds. Reading shown is given in user programmable units (fac- tory default is pennyweights) MESSAGES C nnn... -
Page 8: Section Three
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 - EZ6 MODEL ONLY Your Easy Count (EZ6) scale is capable of weighing in any of the units listed in the DISPLAY SYMBOLS portion of this guide. -

BASIC COUNTING USING THE COUNT KEY (EZ2) To count a number of like objects on the scale, use the following procedure: zero 0.00 count 1. Place an empty container on the scale. Press the zero key. zero count Add 10 2. -
Page 11: Using The Minimum Sample Size And Minimum Accuracy Feature
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 en- sures that the scale will calculate an average piece weight which is nearly equal to the average piece weight of the entire lot. -
Page 12: Reverse Counting Or Kitting
(The sample size requirement can be increased by pressing the sample size (EZ6) or count (EZ2) key repeatedly. The predetermined sample sizes are: 10, 25, 50 and 100 pcs. A custom sample size may be preset using the minimum sample size setup. If preset, the scale will never request a sample size less than the preset minimum sample size.) 3. -
Page 13: Locked Sample Size
5. When you reach the desired sample size, REMOVE the requested num- ber of pieces from the container. 6. Press the count key. If the sample size is not large enough to satisfy the minimum accuracy requirement the display will read “Sub nnn” PC. -
Page 14: Unlocking The Sample Size
UNLOCKING THE SAMPLE SIZE To unlock the sample size, follow this procedure: 1. Remove all weight from the pan and press zero. “0.00” is displayed. 2. Press the sample size key (EZ6) or the count key (EZ2). The scale will display “Add XX.”, where XX is the locked sample size. -
Page 15: Interfacing With A Computer
INTERFACING WITH A COMPUTER Your Setra Easy Count scale is designed to interface with a wide variety of computer equipment. For information on how to connect your scale to a computer and transmit data ask your local authorized Setra dealer for the Setra Easy Count Technician’s Guide, or request a copy from the factory. -
Page 16: Set-Up Functions
Appendix I Set-Up Functions Your Setra Easy Count scale was programmed at the factory to operate in a prescribed manner. Many of the factory settings can be altered by an autho- rized Setra dealer to optimize scale performance for your counting or weigh- ing operation. - Page 17 Printer Settings: Default: Average Piece Weight formatted for bar code printing on a CoStar SETRA250. Print Device Type: CoStar SETRA250 receipt/label printer - English only or APW only in bar code. Auto Count 200 - English/Bar Code on CoStar SETRA250 or dot matrix printer. To print a copy of the scale’s current setup information use the following procedure.
-
Page 18: Print Output Setup
Print Output Setup There are five different print formats that can be selected through the keypad. These print formats are designed for the CoStar SETRA250 receipt/ label printer, an ASCII printer or even another Setra scale (dual scale fea- ture). To select one of the five default print formats, follow the steps below. For more advanced formatting to either an ASCII printer or PC, refer to the Easy Count Technician’s Guide. - Page 19 12. Press the zero key to print an English label with the Net Weight, APW, and Piece Count on a CoStar SETRA250 printer or, press the count key to move to the next selection. 13. The scale will next display “dUAL” for sending the APW to another Setra scale (called dual scale feature).

Page 20: Calibration
Appendix II Calibration Your Setra Easy Count scale is highly stable, and requires infrequent calibra- tion. While it may be span calibrated as often as desired, the factory calibra- tion is adequate for most counting applications. For precise weighing appli- cations more periodic calibrations may be desirable. -
Page 21: Glossary Of Terms
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. -
Page 22: Rs-232 Serial Data Communications
Appendix II RS-232 Serial Data Communications Your Setra Easy Count comes equipped with a bidirectional RS-232 interface using a default baud rate of 2400 and no parity. Users who are interfacing a scale to the Auto Count 200 or to an optional serial printer should follow the installation instructions in the Easy Count Technician’s Guide or the Auto Count 200 manual. - Page 23 Shielded cables must be used with this unit to ensure compliance with the Class A FCC limits. Computers which require handshaking need a connection between two pins on the computer’s connector named DTR and DSR (Data Terminal Ready and Data Set Ready). CTS may also need to be jumpered to RTS at your computer interface (Clear To Send and Request To Send).

Page 25: In Case Of Difficulty
Appendix IV In Case of Difficulty Setra Easy 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. - Page 26 If the scale displays any unusual messages during the warm-up period, or does not return to normal operation, contact an Authorized Setra Service Center or Setra Systems, Inc., as service may be required. If the scale displays the “bUSY” message for an extended period of time, or the displayed reading is unstable, too much vibration or draft may be present.
