SR-Series Manual
Thank you for purchasing the American Weigh
SR-Series digital hanging scale. Please read all operating
instructions carefully before use. Scales are precision
measuring devices and should always be handled with
proper care. To ensure years of reliable service, keep these
simple tips in mind:
• Do not exceed the scale’s 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, calibration
and adjustment may be necessary.
• Allow your scale to warm up for 30-60 seconds before
performing calibration and adjustment (if available).
• 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 your scale in close proximity to strong
radio wave emitting devices such as computers, cash
registers, and cordless phones.
• Gently apply all items to be weighed. Do not shock
load items onto the weighing hook.
• Avoid dropping your scale. The warranty does not
cover damage due to rough treatment or overload.
• Checkthebatteriesrstifyouarehavinganytrouble
with your scale. This simple step can remedy most
scale issues.
• Do not disassemble your scale. This product contains
no user serviceable parts.

of an empty container or vessel for net weight determination.
NOTE: The weight of the container will subtract from the
available capacity.
1. Turn on the scale as described in Section IV.
2. Attach your tare item / empty container using the
hook and wait for it to stabilize.
3. Tap the button. “0.0” will be displayed.

just the weight of the contents.
5. When the container is removed the weight will be
held on the display. Press again to zero the scale.
VIII. Adjustment (Calibration)
Adjustment is performed professionally at the factory.
Only advanced users should perform calibration using the
required weight if the scale is not weighing properly:
