Operation
Calibration and Adjustment
Purpose
Perform calibration to determine the
difference between the value displayed
and the actual weight on the platform.
Calibration does not entail making
any changes within the weighing
equipment.
During adjustment, the difference
between the measured value displayed
and the true weight of a sample is
corrected, or is reduced to an allowable
level within maximum permissible error
limits.
Configuration for Use in Legal
Metrology
Configuration of the weighing
instrument for use in legal metrology
is set by a switch. The switch is located
on the back of the weighing platform
and covered by a protective cap.
Using a verified scale in legal
metrology in the EU:
The Type-Approval Certificate for
verified scales is only valid for non-
automatic weighing instruments. For
automatic operation with or without
additional, integrated equipment,
please follow the applicable national
regulations for the installation location.
§ Before use in legal metrology, the scale
should be calibrated via the internal
calibration equipment at the installation
location: see the “Internal Calibration"
section in this chapter.
$ The temperature range (°C) listed on
the ID label should not be exceeded
during operation.
For Servicing:
External calibration for verified scales
of accuracy class K and l
– External calibration is blocked in legal
metrology (switch cover is sealed)
– External calibration only possible by
removing the seal
If the seal is broken, the validity of
verification will become void and you
must have your scale re-verified.
Using a verified scale in legal
metrology with internal adjustment
equipment:
§ Before use in legal metrology, the
“internal calibration" function should
be carried out at the installation
location.
