1.1 Safety Precautions
The U.S. Solid USS-DBS92 Bench Scale qualifies as state-of-the-art
technology and complies with all recognized safety rules. Improper use

•The scale has a 3-pin power socket equipped with a
ground terminal. To prevent electric shock and to maintain

stability in operation of the scale, be sure to ground the scale.
•Avoid getting the scale wet as it is not water resistant. Any leakage of
liquid into the scale may damage the scale or cause an electric shock to
the user.
•Use a power source (voltage, frequency, outlet type)
adapted to the specification of the scale. If excessive voltage
is used, the scale may overheat and be damaged or cause a fire.
•Operate the scale on a stable, rigid and flat table.
•Handle the scale 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 scale's range, as this may damage
the load cell of the scale.
