Dkd Uncertainty Of Measurement - Sartorius LA Reference Series Operating Instructions Manual

DKD Uncertainty of Measurement

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
– 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"
