Glossary
Data Bits
Low or high voltage signals transmitted through the serial communication data line. Data bits
are transmitted after a Start Bit and before the Parity Bit and Stop Bit. The user can configure
the number of bits to be transmitted between the start bit and stop bit.
Database
A collection of data stored and organized for rapid access and retrieval.
DGKCh
Deutsche Gesellschaft für Klinische Chemie (A German Clinical Chemistry Association).
Dialog Box
A small window that generates from a screen, requiring interaction from a user through the use
of text fields, check boxes, and command buttons. A dialog box, smaller in size than a screen,
does not generally include a row of function buttons.
Diluent
Fluid used to dilute another fluid.
Dilution Factor, Off-Line
A factor defined by the user by which the sample result is multiplied.
Discrete
The state of reactions taking place in their own separate container.
Double Trigger
Two different reagent components, added to the cuvette after sample addition, that initiate the
desired action.
Downgoing
The decrease in absorbance as a reaction progresses.
EIC
Electrolyte Injection Cup.
Electronic Maintenance
Maintenance items are grouped together by frequency of performance. Only the maintenance
items appropriate for the particular system and installed hardware are shown. On the
Scheduled Maintenance Log screen these groups have been placed under separate labeled tabs.
Each of these tabs is accessed by using the touchscreen or by using the mouse. Selecting the
highlighted tabs will reveal the procedures requiring attention highlighted in yellow. Yellow
highlights will also alert the operator when any maintenance item on the respective tabs is due
to be performed.
Endpoint
A reaction that has come to completion before the absorbance measurements are taken. It is
expressed as absorbance (A).
Enzyme Validator
A human serum, albumin-based, value assigned material that can be used as a calibrator to
provide IFCC/DGKCh equivalent answers for selected enzymes.
