1. Introductions
1.1. The Preface
Thank you for purchasing of our CAS scale.
This scale has been designed with CAS reliability, under rigid quality control
and with outstanding performance.
Your departments can enjoy with this high quality reliable CAS product.
We believe that your needs will be satisfied and you will have proper reliability
with in variable weight.
This manual will help you with proper operations and care of the PD-II series.
Please keep it handy for the future references.
1.2. Precautions
To ensure that you get the most from your scale, please follow these instructions.
1. Do not disassemble the scale. When any damage or defect occurs, contact your CAS authorized
dealer immediately for proper repair.
2. Do not overload beyond the maximum weight limit.
3. Scale must be grounded to minimize electricity static. This will minimize defect or electric shock.
4. Do not pull the plug by its cord when unplugging. Damaged cord could cause electric shock or
fire.
5. To prevent from fire occurring. Do not place or use the scale near flammable or corrosive gas.
6. To reduce electric shock or incorrect reading. Do not spill water on the scale or place it in humid
condition.
7. Avoid placing the scale near heater or in direct sunlight.
8. Insert plug firmly to wall outlet to prevent electric shock.
Make sure to plug your scale into the proper power outlet. For maximum performance,
plug into a power outlet 30 minutes before the usage for warm up.
9. For consistent and accurate reading, maintain periodical check by your CAS authorized dealer.
10. Avoid sudden shock to the scale. Internal mechanism could be damaged.
11. Grab on the bottom of the scale when moving. Do not hold by the platter.
12. Place the scale on firm and temperature consistent environment.
13. 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.
14. Keep the scale away from other electromagnetic generating devices. This may interfere with
accurate reading.
