The Meter sink performs various measurements on the source's data. The measurement values can be displayed in segment displays (default) as well as gauge displays. Appearance of the meter can be configured in the program settings. Multiple sources can be connected to the meter and per source, multiple measurements can be displayed, in individual displays. Sources with time domain data and sources with frequency domain data can be connected to a meter. For each connected source, a column with displays is added to the meter window, a caption at the top of the column indicates the source by its icon and name or alias. Connecting a source can be done in two ways:
The following measurements are available:
The measurements are performed over all post samples of the associated source. In the program settings can be determined which measurements are default shown when creating a meter.
To control the behavior of a display of the Meter, several properties are available. These can be accessed through a popup menu which is shown when the display is right clicked.
When multiple sources are displayed in a meter, they can be distinguished from each other by their Color. Two color settings are available for a meter display.
The Digits option determines how many digits are used to show the value on the segment display. Three different options are available:
The Decimals option determines how many decimal positions are used to show the value on the segment display. Three different options are available:
The option Auto prefix determines whether a prefix (µ m k M G etc.) is added to the displayed unit on a segment display. The displayed value is shown accordingly. Auto prefix is default on. When Digits and Decimals are set to Auto detect, Auto prefix will be fixed to on.
The Range option determines the full scale range of a gauge display. Two options are available:
The property Measurement determines which measurement is performed on the data of the associated source of the display. A submenu allows to select from the available measurements.
The property Type determines whether a segment display or a gauge display is used to show the value.
The Delete action deletes the display.
Some actions that are related to a connected source of a meter are available. These can be accessed through a popup menu which is shown when the source caption is right clicked.
The action Add measurement adds a display with a specified measurement to the column of displays for the associated source. The measurement to add can be selected from a sub menu.
To remove a source from a meter, the Disconnect source action can be used. This will remove all displays and caption for that source from the meter window.
To control the behavior of the Meter sink, several properties are available. These can be accessed through a popup menu which is shown when the sink is right clicked in the object tree.
The data range over which the measurements are calculated can be set to one of the following settings:
The Copy to clipboard action copies the values of all displays including layout to the Windows clipboard, from where it can be pasted in various applications. The Copy to clipboard action is available in the popup menu.
When the Always on top property is switched on, the Meter window cannot be hidden under other windows of the Multi Channel oscilloscope software. The Always on top property is available in the popup menu.
