The CAS PD-II Scale is a versatile scale that may be configured for OZ or LB readings. Scale readings may be transferred to Cash Register Express/Restaurant Pro Express software for items that are sold by weight. The scale is very sensitive and may lose calibration during shipment. The calibration process is relatively simple and may be performed onsite by the end user. Scale certification is usually required shortly after implementation by the local governmental agency that handles weights and measures.

Common Problems:

I.    After No Load Calibration, Scale does not read zero
Perform Full Capacity Calibration
     A. Acquire an item with a known weight of 15 lb (3 reams/500 pages of 20 pound printer paper is equal to 15 lb. You may be able to combine other items of known weights, or use another manual scale to confirm the weight before you continue)
     B. Power off the scale
     C. Remove the Platter
     D. Loosen the left Calibration bolt
     E. Remove the right Calibration bolt and slide Calibration Plate out of the way
     F. Use screw driver or pen to press the recessed Calibration Button while switching on the scale
     G. Release Button when scale flashes “CAL”
     H. Display will show “C – 0”
     I. Press the “lb/oz” button until display shows “C – 3”
     J. Replace the Platter
     K. Press “ZERO” button and the display should read “UnLoad”
     L. Press “ZERO” button and the display should read “ StABLE “ and then “ LoAD “
     M. Place the maximum capacity on the platter according to the model/capacity (15 lb, 30 lb, etc)
     N. Press “ZERO” button
     O. Display will show “ C-3 End “ and then “ C-3 “
     P. Press  the “lb/oz” button until the display shows “C-0”
     Q. Remove all weights from the scale
     R. Press “ZERO” button to activate an internal diagnostic and zero of the scale
     S. Replace the Calibration Plate and screw

 

II. I don’t have exact weight to perform a Full Capacity Calibration. Is there another way?
Perform a Percent Capacity Calibration, which uses a percentage of the total weight capacity to calibrate
     A. Acquire a weight with a known percentage of the total scale capacity
          1. Example for 15 lb capacity scale
          2. Use 1 ream 20 lb paper (which weighs 5 lbs)
          3. Calculate Percentage: (5 lb weight of paper ream / 15 lb scale capacity)*100 = 33%
     B. Power off the scale
     C. Remove the Platter
     D. Loosen the left Calibration bolt
     E. Remove the right Calibration bolt and slide Calibration Plate out of the way
     F. Use screw driver or pen to press the recessed Calibration Button while switching on the scale
     G. Release Button when scale flashes “CAL”
     H. Display will show “C – 0”
     I. Press the “lb/oz” button until display shows “C – 7”
     J. Replace the Platter
     K. Press “ZERO” button and the display should read “PER 10”
     L. Use the “lb/oz”  button to set the weight percentage to the calculated value
     M. Press “ZERO” button and the display should read “UnLoad”
     N. Press “ZERO” button and the display should read “ StABLE “ and then “ LoAD “
     O. Place the maximum capacity on the platter according to the model/capacity (15 lb, 30 lb, etc)
     P. Press “ZERO” button
     Q. Display will show “ C-3 End “ and then “ C-3 “
     R. Press  the “lb/oz” button until the display shows “C-0”
     S. Remove all weights from the scale
     T. Press “ZERO” button to activate an internal diagnostic and zero of the scale
     U. Replace the Calibration Plate and screw

 

III. Using HyperTerminal to test station connectivity to scale
     A. Turn off CRE/RPE on the station connected to the scale
     B. Open HyperTerminal from C:POSNationextras folder, or download from Internet
     C. Connect To Dialog Box
          1. Key in area code: 555 (if required)
     D. Phone and Modem Dialog Box – Click OK accepting defaults
     E. Enter Session Name: CASTEST
     F. Click OK
     G. Connect Using: COM1 (or other assigned COM port)
     H. Port Settings:
          1. Bits per second: 9600
          2. Data bits: 7
          3. Parity: Even
          4. Stop bits: 1
          5. Flow Control: None
     I. Click OK
     J. Go To Call>Disconnect
     K. Go To File>Properties>Settings Tab
     L. Select “Windows Keys” radio button
     M. Click the “ASCII” Setup” button
     N. Check “Echo typed characters locally”
     O. Click OK twice to close both dialog boxes
     P. Go To Call>Call to connect to the scale
     Q. Place weight on the scale for testing
     R. Type “W” and press Enter
     S. Scale should reply with weight
     T. Successful test indicates station is properly connect to scale, and application settings may need to be adjusted
     U. Failed test indicates that there is a connectivity problem with the scale on the assigned port.
          1.  Attempt moving to another port
          2. Attempt uninstalling all unused printers on the computer stations, which may conflict with the COM port communications
          3. Verify serial cable is a Null Modem cable
          4. Reboot to resolve some driver conflicts
