1. Introduction
1.1. 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.
WE hope that your departments enjoy with high quality of CAS product.
This manual will help you with proper operations and care of the EB series.
Please keep it handy for the future references.
1.2. Precaution
•
Make sure that you plug your scale into the proper power outlet.
•
Place the scale on a flat and stable surface.
•
Plug into a power outlet 30 minutes before operations.
•
Keep the scale away from strong EMI noises may cause incorrect weight readings.
•
This scale must be installed in a dry and liquid free environment.
•
Do not subject the scale to sudden temperature changes.
•
Do not subject the platter to sudden shocks.
•
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.
