TL-Series Manual
Thank you for purchasing the American Weigh
TL-Series 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.
•
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 cordless phones.
•
Suspend the scale from a stable point free from
vibration.
•
Do not drop items onto the weighing hook. This may
cause damage to the load sensor.
•
Avoid dropping your scale. The warranty does not
cover damage due to rough treatment or overload.
•
Check the batteries first if you are having any trouble
with your scale. This simple step can remedy most
scale issues.
•
Calibration is performed at the factory. Only
experienced users should perform calibration when
the scale requires it.
