1.1 Safety Precautions
The U.S. Solid USS-DBS86 Precision Balance qualifies as state-of-the-art
technology and complies with all recognized safety rules. Improper use

•The balance has a 3-pin power socket equipped with a

2
ground terminal. To prevent electric shock and to maintain stability in
operation of the balance, be sure to ground the balance.
•Avoid getting the balance wet as it is not water resistant. Any leakage
of liquid into the balance may damage the balance or cause an electric
shock to the user.
•Use a power source (voltage, frequency, outlet type)
adapted to the specification of the balance. If excessive
voltage is used, the balance may overheat and be damaged or cause a
fire.
•Operate the balance on a stable, rigid and flat table.
•Handle the balance carefully. It is a precision device,
subjecting it to impact may result in a malfunction.
•If the device is not be used for a long period of time, the power
should be turned off and disconnect the power cable.
•Do not disassemble, remodel or repair this product or accessories.
•Do not weigh items larger than the balance's range, as this may
damage the load cell of the balance.
