AMW-Series Manual
Thank you for purchasing the American Weigh AMWSeries 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.

IV. TROUBLESHOOTING
The primary reasons for inaccuracy or malfunction
are low batteries, incorrect calibration, overload or
operating on an unstable surface. Please keep this in
mind and maintain and operate your scale properly.
This scale is a precise instrument and must be
handled with the utmost care and caution.
[Display]
Elimination of errors
Nothing, Battery-Symbol, [lo] or [88888]
Change the batteries.
[OUE2] Recalibrate the scale as shown above.
[EEEEE] You are overloading the scale. Remove the
excessive load immediately!
[LLLLL] The delicate weighing load cells have
been damaged by misusing the scale
(i.e. it was shocked, dropped or
overloaded). You can try recalibrating the
scale. If the load cell has not been
damaged too much it will work
again after recalibration.
[UNST] Use the scale in a more stable position
