Ash Tray Scale Manual
Thank you for purchasing the American Weigh Ash
Tray Scale digital pocket scale. Please read all
operating 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 warm up for 30-60 seconds
before performing calibration (if available).
• Store your scale in a clean, dry location. Dust, dirt,
and moisture can accumulate on the weighing sensors
and electronics causing innacuracy or malfunction.
• Avoid using your scale in close proximity to strong
radio wave emitting devices such as computers, cash
registers, and cordless phones.
• Always weigh on a at and 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.
