1. PREFACE
A. Introductions
Thank you for purchasing our CAS MW-II Series.
These series has been designed with CAS reliability, under rigid quality control
and with outstanding performance. Your specialty departments can enjoy
these high quality reliable CAS products.
We believe that your needs will be satisfied and you will have proper reliability.
This manual will help you with proper operation and care of the MW-II series.
Please keep it handy for future reference.
B. Precautions
1. Make sure that you plug your scale into the proper power outlet.
2. Place the scale on a flat and stable surface.
3. Plug into a power outlet one hour before operations.
4. Keep the scale away from strong EMI noises may cause incorrect weight readings.
5. This scale must be installed in a dry and liquid free environment.
6. Do not subject the scale to sudden temperature changes.
7. Do not subject the platter to sudden shocks.
8. If the scale is not properly level, please adjust the 4 legs at the bottom of the scale (turn legs
clockwise or counterclockwise) so as to center the bubble of the leveling gauge inside the indicated
circle.

C. How to Confirm the Setting Value
1. Turn on the power and connect the scale to PC with RS232C cable.
2. Open the terminal on PC and adjust COM1, COM 2 and transmission speed to the scale.
3. Press the P on the keyboard of PC then you will hear the beep on the scale. Check the weight
on the terminal.
4. If there is no response on step 3, check the cable, port, transmission speed.
5. Enter 83419 on the PC terminal, you will go to debugging mode.
6. Press Ctrl+R key, you will see the data as below on the PC terminal. If not, enter 83419 slowly.

B. Troubleshooting
1. “CAL. Er”
Er”
1) Go to calibration mode. CAL Switch is located in the battery cover at the bottom of the
scale. While pressing the switch, turn on the power then you will go to calibration mode.
2) Span calibrate the scale on “C.SPAN”
C.SPAN”menu. Refer to Span Calibration on page 6.
3) Press the MODE key twice, the display shows “C.trim”
C.trim”.
trim”
4) When the display shows “C.trim”,
trim” press the CAL switch and SET key.
5) The display shows AD value, this value is flickering because it is not filtered. If it is not
flickering, it means a failure of AD part.
6) Make sure that there is nothing on the platter and press the TARE key.
7) Place the weight of maximum capacity on the platter.
8) If the value is lower than 200.000, check the output of load cell. This value should be
greater than 200.000.
9) Turn the power off and on. You will go to normal mode. If the display shows “CAL. Er”
Er”,
check EEPROM.
2. “Init ?”
?”
1) If the display shows “ Init ?”
?”, press the SET key. If you press another key, EEPROM is
not initialized and go to next step.
2) “CAL.Er”
CAL.Er”is displayed in 10 seconds.
3) Span calibrate the scale again. Turn the power off and on.
4) If the display shows still “Init ?”
?”, check EEPROM.

Frequently Answers and Questions

What is the maximum capacity of the MW-II Series scales?
The maximum capacity varies depending on the model. The MWII200 has a maximum capacity of 200g, the MWII 300 has a maximum capacity of 300g, the MWII 2000 has a maximum capacity of 2kg, and the MWII 3000 has a maximum capacity of 3kg.
What are the weighing units available on the MW-II Series scales?
The MW-II Series scales offer multiple weighing units: g, oz, tI, PCS, dwt, mom, ct, GN, lb, and %.
How do I perform a span calibration on the MW-II Series scales?
To perform a span calibration, press the CAL switch while turning on the power. The display will show "CALMod" three times and then "C.SPAN". Press the SET key to enter the "C.SPAN" menu. Follow the on-screen instructions to complete the calibration process.
What is the meaning of the "OL-L" error message on the MW-II Series scales?
The "OL-L" error message indicates an underload error. This means that the weight placed on the platter is lower than the standard weight for counting and percent modes. For MW-II 300, the standard weight is 2g for counting mode and 5g for percent mode.
How do I connect the MW-II Series scales to a PC or printer?
The MW-II Series scales are equipped with an RS232C interface for communication with a PC or printer. Refer to the "Serial Interface" section in the manual for the correct connection details and data transmission frame structure.
