Additional Functions
Calibrating the Scale
The second adjustment, calibration, defines and sets a standard
reference weight range against which all product weights are com-
pared. If your scale is set for weighing in pounds, this range is 0 -
30 pounds, and, if your scale is set for weighing in kilograms, the
range is 0 - 15 kilograms. The scale must be calibrated upon initial
installation, whenever the scale cannot be zeroed, when the scale
diagnostics indicate a calibration error, when the weighing measure
(pounds or kilograms) is changed, or when the scale module has
been replaced.
Normally, once the scale has been calibrated, the calibration must
be verified and/or approved by a local regulatory body. In many
areas of the United States, the scale calibration switch must be
sealed before being placed into service. Consult the agency respon-
sible for regulating weighing devices in your area to ensure that you
are meeting all legal and regulatory requirements. Chapter 5, Cali-
bration, describes the calibration sequence and verification process.
Calibration can only be performed if the tamper seal that secures
access to the Calibration Switch is broken and the switch cover is
legally
removed. Breaking the seal may render the scale inoperable
until it has been recertified and a new seal attached. Consult your
local regulations before removing the calibration seal if you are
unsure of the legal requirements. Although the scale will physically
continue to weigh products, a broken seal may require recertifica-
tion by a proper authority as designated by your local laws.
