Thank you for purchasing US-EXCEL digital scale. Please read all operation
instructions carefully before use.
Scales are precision instruments and should always be handled with proper
care. To ensure years of reliable service, keep these simple tips in mind:
• Do not exceed the scales maximum capacity. Overloading your scale can
permanently damage it!
• Avoid exposure to extreme heat or cold. Scales perform best at normal room
temperature. If temperatures have changed dramatically, recalibration may
be necessary.
• Allow your scale to acclimate to the room temperature for at least one hour
before use.
• Store your scale in a clean, dry location. Dust, dirt, and moisture can
accumulate on the weighing sensors and electronics causing inaccuracy or
malfunction.
• Avoid using you scale in close proximity to strong radio wave emitting
devices such as computers, cash registers, and cordless phones.
• Always weigh on a flat level surface, free from vibrations and drafts. The
corner of a room is usually the most stable.
• Gently apply all items to be weighed. Do not drop items onto the weighing
platform.
• Avoid dropping your scale. The warranty does not cover damage due to
rough treatment or overload.
