Purpose
Display of the dynamic uncertainty
of measurement in conformance with
the specifications listed on the DKD
Calibration Certificate.
Features
After Technical Service has prepared
the balance:
– A service technician performs on-site
DKD calibration of your balance to
determine its uncertainty of measure-
ment. On the DKD Calibration Certifi-
cate, the measurements and the uncer-
tainty for the initial sample weight are
recorded. Then the service technician
enters this data in the balance.
– Display of the factor and the exponent
entered; activation by accessing the
Setup menu: Device information:
DKD uncertainty of measurement
– Display of the uncertainty of measure-
ment, for example:
Absolute uncertainty of measurement:
U = 0.54 g
Relative uncertainty of measurement:
U* = 0.00045 %
Process accuracy:
PA = 0.00013 %
– Display of up to 2 DKD uncertainty
of measurement values:
The first two calculated values that are
actviated by selecting “Display” in the
Setup menu are shown.
– This function can be assigned to a key
identified by the fourth or fifth soft key
(from the right, F4 or F5).
The soft key is identified by
U/PA
– Resolution
The absolute uncertainty of measure-
ment is displayed with a 10 times higher
resolution.
The absolute uncertainty of measure-
ment and the process accuracy are
displayed with up to 5 decimal places
(2 significant decimal places).
– Printout of the addend and the factor
of the uncertainty of measurement
when the power is turned on:
In the Setup menu, select “Auto print
upon initialization: All values.”
– Display
--------- (for U* and
PG) for:
– Calculated net values (e.g., counting,
weighing in percent, etc.)
– Values greater than 100%
– Net value equal to “zero”
