Popup-Menus are activated with a right click. They contains essential commands to most of the workview-areas.
Glossary - Begriffe
ADC
Analog-Digital Converter, this electronic components are used to digitize analogous measuring-signals and make them readable to microprocessors. Depending on the required accuracy the digitizing is performed with 8, 16 or 24 bit resolution.
Auto Message
an important message, sent imediately to the central monitoring system
Dragging
Dragging is used to move an object on the screen from one location to another. Dragging is also used to resize an object by moving the objects border. Click and hold down the mouse button to move or resize an object.
Focus
A focus is a visible border or color-effect emphasizing preselected controls
Filter
A filter is used to prevent invalid character-input. The set of valid characters are usually annotated with rectangular brackets, for instance
[0-9], [ASCII 32-127]
Final-Values
Final-Values are the result of the signal-postprocessing. Post-processing is used for data-correction by applying calibration-values, or if the use of different technical units is required for data-evaluation (i.e. ppm versus µg, or m/sec versus km/h).
GUI
A Graphical User Interface (GUI) allows the user to interact with the system in a shophisticated way.
HMV
Halfhour-Meanvalues (HMV) are the result of the standard data-processing. The environmental monitoring system is capable to store up to 21 days of HMV for up to 48 components.
A component may be a physical or a logical component. For instance the wind-gust is described by 3 logical components: wind-gust, related wind-direction and related time-marking of the occurence.

Popup-Menu
Popup-Menus are activated with a right click. They contains essential commands to most of the workview-areas.
Progress Bar
A progress-bar is an indicator showing the progress of timeconsuming operations
Raw-Values
Raw-Values are the result of the signal-conversion - the electrical input-signal is converted in technical units by use of a polynomial. For instance the signal-voltage of the temperature-sensor is converted in °Celsius.
RS-232
RS-232 is a communication-link used for data-transfer over short distances (suitable for up to 15 meters of cable-length).
Sub ID
The sub-identifier is used to distinguish devices of same type. The unique Device ID consists of two digits describing the type of measuring device (ie. temperature sensor = 13) and a sub ID from 1 - 9.
Task-Bar
The task-bar is used by the operating system (ie. Win98, WinNT) to indicate running user-applications. A small part of the task-bar is provided for system-activities, for instance time-display.
Tooltip
A hooverhelp or tooltip is used to explain abbreviations or technical expressions
User Password
A User Password is required to access data or execute operations
VMV
Variable-Meanvalues (VMV) are the result of user-defined data-processing. VMVs may be established for up to 8 components. The storage of VMVs depends on the number of components and the choosen time-interval.
The environmental monitoring system is capable to store exactly 3 days of VMV for 8 components with measuring-intervals of 1 minute. If the number of components is decreased, or the time-interval is increased, the storage-capacity will increase accordingly.
