SWS-PCS Retail Scale Instruction Manual
Thank you for purchasing Model SWS-PCS Retail Scale. Please read all operating instructions
carefully before using and note the following points
Avoid using in extreme heat, cold or wet and the environment which has intensive change in
temperature, humidity and pressure.
Allow sufficient warm up time after turn the scale on, to allow the internal components and load
cell to have enough time to stabilize and balance heat.
Do not read the scale long time after the reading is stable, as there might be minor changes on
output signal of the load cell and electronics after long time.
Do not operate near an in-use cell phone, radio, computer or other electronic device as these
devices emit RF and maybe cause unstable scale readings.

15.1 Under the normal working mode, press and hold 8 and ON/OFF key for more than 3s to enter this mode. In
this mode, you can set the origin point.
15.2The weight window displays “SETUP”, the unit price window displays “ORG.X”(Origin.X), and the total price
window displays the X direction offset number.
15.3 Use digit keys and Clear to input X offset（0-255），Press Enter key to confirm the input and go to the next
step.
15.4 The weight window displays “SETUP”, the unit price window displays “ORG.Y”(Origin.Y), and the total price
window displays the Y direction offset number.
15.5 Use digit keys and Clear to input Y offset（0-255），Press Enter key to confirm the input and the Printer will
print out a new blank label sample using new start position, and then exit this mode
16.PLU upload and download
16.1 Connect the scale to PC through RS232 interface, run EHC-PM.exe, this software can only process *.xls
files. ( he following is Example for SWS-PCS-30lb)
16.2 Software searches all serial ports on PC, and tries to connect with the scale. In the Status bar, it will
separately display present serial port, baud rate, data format. Take the following figure for example,
“COM2,2400,8N1” refers to the present serial port COM2, baud rate 2400, data format 8N1. If the
connection status displays “Connecting the scale”, it means the Software is searching SWS-PCS scale, if it
displays “The scale is connected”, it means the Host has been connected with the scale.
16.3 The Software can search all the present serial ports automatically, until connect with the scale. Manual
connection is also available by use “Serial Set” in “Serial” menu.

16.4Press “Open” or “open file” button in “File” menu，it will first remind you whether to save the current file, and
then open the file and dialogue box to choose and open the right file.

16.5 Choosing “Down Load” in “Serial” menu ，the scale will display “DNLOAD”, the status bar will display the
present download information, if it displays “downloading business name”, it means it’s downloading the store
name. If it displays “Downloading Mxx”, it means it’s downloading the information of M1~M9 (direct unit price). If it
displays “Downloading No. xxx”, it means it’s downloading the information of PLU1~265. “Download successful”
will be displayed after downloading finished.
16.6Choose “Upload” in “Serial” menu, the scale will display “UPLOAD”. the status bar will display the present
upload information, if it displays “uploading business name”, it means it is uploading the store name. If it
displays “uploading Mxx”, it means it is uploading the information of M1~M9. if it displays “uploading No.
xxx”, it means it is uploading the information of PLU1~265. “Upload successful” will be displayed after
uploading finished.

16.7Date and Time setting
Choose ”Pair” in “Serial” menu to open the date and time setting dialogue box, it will display the system clock
of PC, press “Confirm” or exit the dialogue box directly. After the software send date and time setting data to
the scale, it will display “Pair successful.”.

1 7 .LCD test mode
18.1 Long press the ON/OFF+PRIN key, until all segments of LCD are displayed
18.2 (a) Press 0 key--- all segments are shown;
(b) Press 1 key --- different segments will be shown;
(c) Press 2 key --- segments on different COMs will be shown;
(d) Press EN ER key ---segments will be shown in turn of above a-b-c steps
18.3 Press EXI key --- exit this mode
