U S SOLID USS-DBS62 Analytical Balance

INTRODUCTION

This analytical balance works on electromagnetic force compensation technology and micro processor which implements high speed stabilization and high reliability. It can be widely used in industry, agriculture, commerce, schools, scientific research and other institutions to quickly weighing the quality and quantity of objects.

Safety Precautions
Verify that the AC Adapter input voltage matches the local AC power supply. Use the scale only in dry locations.
For best results, use the scale in the specified optimum operating temperature. Use your scale with care, gently loading items to be weighed onto the center of the pan. Avoiding rough treatment will aid in the life of your scale.
Do not suggest to use in below environment.

TROUBLESHOOTING

Power transformer is damaged;

| Plug in adapter; Change the fuse;
Change the power transformer; If problem persists, send the balance to the Technical Service for repair.
Unstable display|

Bad working conditions; Air flow Something between the scale pan and working table.

The power exceeds its permissible value and is unstable; Static electricity

| Improve the working condition, Close the windshield;

Remove the pan and clean well the balance surface;

Connect the balance to power supply 110-220 V AC Static Elimination

Poor accuracy|

Improper calibration

The weight of the recipient has not been tared Big temperature difference The balance is not horizontal

| Make calibration Make tare
Put into suitable enviroment Adjust level of balance
