Calibration and Adjustment

Purpose
Calibration is the determination of any difference between the measured value
displayed and the true weight (mass) of a sample. Adjustment is the correction of
this difference, or its reduction to an allowable level within maximum permissible
error limits.
Using Verified Balances as Legal Measuring Instruments in the EU:
Before using your balance as a legal measuring instrument, internal calibration
must be performed at the place of installation.
Features
Calibration|adjustment can be performed only when:
– There is no load on the balance
– The balance is tared and
– The internal signal is stable.
– The sensitivity of the balance can be corrected by a max. of 2%.
– The balance can be adjusted using the Sartorius density determination kit YDK...
If these conditions are not met, an error message is displayed (Err 02).
You can use any of the following weight units in calibration|adjustment:
Cal.Unit - Grams, Kilogr (not for verified models)
– The automatic calibration and adjustment function (isoCAL) can be started,
once the time or temperature values have been exceeded.
External Adjustment on Verified Balances
– When the balance is used in legal metrology, external calibration is blocked
as follows:
– The setting of the menu access switch is locked
– The cap over the menu access switch is sealed
To block calibration|adjustment:
– Select Cal.|Adj. - Blocked
– Close the menu access switch on the back of the balance
For details on generating an ISO|GLP-compliant printout of calibration|adjustment
results: System settings and report templates, see from page 59.
Following calibration|adjustment, the application parameters are cleared.
Internal Calibration|Adjustment
In the operating menu, select Cal.|Adj. - Cal.Int..
The built-in motorized calibration weight is applied and removed automatically for
internal calibration.
§ Select Calibration|Adjustment: Press C
> The built-in weight is applied automatically
> The balance|scale is adjusted
> The built-in calibration weight is removed
