SR-Series Manual
Thank you for purchasing the American Weigh SRSeries 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.
• Hold the hanging scale steady when obtaining weight
measurements.
• Gently apply all items to be weighed. Do not drop
items onto the weighing hook.
• Avoid dropping your scale. The warranty does not
cover damage due to rough treatment or overload.
