CHAPTER-I THE GENERAL 

INTRODUCTIONS

A. PREFACE

Thank you for the purchasing of 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 AD series.
Please keep it handy for the future references.

B. THE PRECAUTIONS

1.

Check the power voltage.

2.

Place the scale on a flat and stable surface.

3.

Level the scale with four adjusters.

Bubble of the level should be centered.

4.

Plug into AC outlet 10 minutes before operations.

5.

Keep the scale away from strong E.M.I, noises.

6.

This scale must be installed in a dry and liquid free environment.

7.

Do not expose the scale to sudden temperature change.

8.
