External Calibration in Verified
Balances of Accuracy Class K
– External calibration is blocked
when the balance is used in
legal metrology
> External calibration can only
be released after removing the
verification control seal, in which
case the validity of the erification
becomes void and the balance
must be re-verified
– External calibration can now
be performed
Factory Settings
Calibration/adjustment mode:
Selection mode (1 9 12)
Calibration/adjustment sequence:
Adjustment automatically follows
calibration in a single operation
(1 10 1)
Automatic initiation of calibration/
adjustment (isoCAL function):
isoCAL on (1 15 5)
ISO/GLP printout: off (8 10 1)
Adjustment can be performed
– automatically following calibration
(1 10 1); or
– if desired, the adjustment
operation can be started man-
ually after calibration (1 10 2)
You can also configure whether
the calibration mode
– will be activated according
to the specific setting (by setting
1 9 1, 1 9 3 or 1 9 4), or
– can be selected by the user after
pressing the q key (1 9 12).
You can have the balance
automatically display an adjustment
prompt after a certain time interval
has elapsed since the last
calibration/adjustment or when
the ambient temperature changes by
a defined amount.
You can also configure the balance
to perform calibration and
adjustment automatically (isoCAL)
when the pre-set time and/or
temperature limit is reached
(1 15 3 and 1 15 5).
You can have the calibration/
adjustment results documented in
a ISO/GLP-compliant printout.
Releasing Access to External
Calibration in Verified Balances
of Accuracy Class k
§ Remove the covering plate from
the back of the balance housing
§ Move Switch 1 in the direction
of the arrow
> Switch down:
external calibration accessible
Switch up:
external calibration blocked
> Note:
Do not move Switch 2
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.
Adjustment is the correction of this
difference between the measured
value displayed and the true
weight (mass) of the sample, or the
reduction the difference to an
allowable level within the maximum
permissible error limits.
Available Features
Your balance can be calibrated
externally (menu item 1 9 1 or1 9 3)
or internally (1 9 4).
External calibration can
be performed
– with the pre-set weight value
(1 9 1), or
– with a user-defined weight value
(1 9 3)
