Term Explanation
Checksum
is a method of identification, display and control of the software version. It is calculated by the
Q2 itself. More Information about this enCore device used control method can be found in the
instructions "enCore FC1 - Basic System with SFBs"
DBB Technology is a valve sealing technology for gas flows. Through a series circuit of two solenoid valves with
a vent between them, the mixing or contamination of gases is prevented even when there are
leaks in the valves.
Display is the collective term for all representations and views on the device screen
enCore
(Abbreviated as: enCore FC) Summary of different device types used as process computers.
Flow Computer
These include, for example, the enCore ZM1 status converter, the enCore MC1 monitoring and
monitoring unit and the enCore FC1 flow computer. GasLab Q2 also uses this software basis
for data management..
Error List helps the user to identify errors and reconstruct the history of the disturbance gradient.
Messages are entered with the comings and goings in the error list, and recorded in the
logbook.
Event is generated when a measurement violates a user-specified state. The coming of such an
event is logged with time stamp in the error list. These events can't be accepted and disappear
automatically when invalid. All notices will be logged in the logbook.
Export value The functional blocks of the software make results available, which can be further processed
by other function blocks. These results are called "export values".
Fiscal parameters are signed with one of these symbols
when SSW is closed. This option is not used when the SSW is open. If you operate the device
with closed SSW parameter with this symbol
this symbol
change will be logged there and therefore monitored.
Gas Quality are devices that measure the heating value of gases automatically. Calorific value, density at
Analyzers base conditions and carbon content are determined from the values of the sensors.
Location of use or of installation is the room or space where the device is present. It must meet the specified
preconditions, the manufacturer, authorities and operators.
Logbook is a protocol archive that can be used by all software components.
It can record all deviating situations e.g. Errors from the normal measurement mode.
Message or Signal is an event that is received and processed as a long unsigned integer. It is valid for a
number of evaluation runs of the device. Each time the event changes, the number increases
beginning with 0, whereby the evaluation cycle of occurrence can be detected. This counter
can be reset by a user with the appropriate user rights
Authorizied A person who has the ability and is authorized, because of his or her technical training,
metrology expert knowledge and experience, to execute fiscally protected tasks in gas systems within the scope
of legal metrology. A metrology expert is trained to work with fiscally protected devices and
systems, and is acquainted with the relevant standards and regulations that apply in specific
countries.
Operating mode Operating modes are states that the device can be in use.
Operational Also called calibration gas, is held in cylinder connected firmly to the Q2 and is part of the
calibration gas measuring device. It is a mixture of methane-clean gas and carbon dioxide with fiscal
established properties is required for automatic calibration.
Ordinal number archived data has a serial number (automatically assigned identification number). This is
structured in such a way so that the first archive entry has the number 1 for each subsequent
entry, the number is increased by one.
Process gas is the gas which has to be analyzed or measured. It is supplied to and through the device in
normal operation and is also called sample gas
is an electrical system in which the voltage can't exceed Extra-Low Voltage under base

conditions, and under single-fault conditions, except earth faults in other circuits (IEC 61140
Low Voltage (PELV)
defines a PELV system). Please contact the Elster GmbH in if you want to use this system
because a modified wiring is required.
