Calibration/Adjustment
Purpose
Calibration is the determination of the
difference between the weight readout
and the true weight (mass) of a sample.
Calibration does not entail making
any changes within the balance/scale.
Adjustment is the correction of any
difference between the measured value
displayed and the true weight (mass)
of the sample, or the reduction of the
difference to an allowable level within
the maximum permissible error limits.
Using Verified Balances/Scales as Legal
Measuring Instruments in the EU*:
Before using your balance/scale as a legal
measuring instrument, you must perform
“internal calibration" at the place of
installation after the warmup period.
Features
Calibration/adjustment can be performed
only when
– there is no load on the balance/scale,
– the balance/scale is tared,
– the internal signal is stable.
If these conditions are not met, an error
message is displayed (Err 02).
Adjustment can be performed
– automatically following calibration
(menu code 1 10 1) or
– manually, at operator discretion, after
calibration (1 10 2)
* including the Signatories of
the Agreement on the European
Economic Area
The weight displayed for the sample on
the balance/scale must not differ from the
nominal weight by more than 2%.
You can use any of the following
weight units to calibrate/adjust: g, kg, lb
(1 11 1 to 3)
You can block calibration/adjustment
of the balance/scale:
– Select menu code 1 9 7, and
– Close the menu access switch on the back
of the balance/scale
You can have the calibration/adjustment
results documented in a ISO/GLP-compliant
printout (see page 52).
For service technicians only:
External Calibration in Verified Balances/
Scales of Accuracy Class K
– External calibration can be made accessible
only after removing the verification
control seal.
> In this case, the validity of the verification
becomes void and the balance/scale must be
re-verified.

20
Calibration/Adjustment Sequence
You can configure the operating menu
so that:
– adjustment automatically follows calibra-
tion in a single operation (1 10 1), or
– the operator chooses whether to end
the calibration/adjustment routine or
have adjustment performed (1 10 2)
If there is no deviation, or if the
difference is within the effective requirements for accuracy of measurements,
it is not necessary to adjust the balance/
scale. In this case, you can end the
calibration routine following calibration.
Two keys are active at that point:
– q = start adjustment
– c = end the calibration/
adjustment routine
