Digital Meter
Use the digital meter to display the values of the connected data channels
numerically. By default the digital meter displays the current value.
However, the digital meter also can display the mean value, the root mean
square, the minimum, or the maximum of the current data block. You can add
a trend display, which shows whether the last value was greater or smaller
than the previous value, to the digital meter. DASYLab displays if the upper
limit is exceeded or the lower limit is undershot, with color changes. If
several data channels are connected, each data channel has its own digital
meter in the display window.
List
Use the list module for the numeric display of data channels in a table. The
table displays one column for each data channel. The first column can display
the measurement time, the time, or the measurement numbers. Whereas the
digital meter always displays the current value, you can look back at previous
measurement values with the scroll bar in the list module.
Analog Meter
Use the analog meter to display the values of the connected data channels in
a gauge display. By default the analog meter displays the current value.
However, the analog meter also can display the mean value, the root mean
square, the minimum or the maximum of the current data block. If several
data channels are connected, each data channel has its own analog meter in
the display window. The scale can comprise a quarter circle or a three-quarter
circle like a tachometer. You can highlight the upper or the lower limit range
of a scale in color, you can enable the trend display, and you can select the
greatest and the smallest measured value with a drag indicator.
Bar Graph
Use the bar graph to display values of the connected data channels as bars,
triangles, thermometers, or as LEDs. By default the bar graph starts at the
smallest value on the scale. For example, if the value range is
-10 to +10 ,
you can set the start point to zero at the center of the value range. Therefore
you can see during the measurement whether the bar is in the positive or in
the negative range. If the upper limit is exceeded or the lower limit is
undershot, DASYLab displays this with color changes so that, in the LED
display, for example, red diodes light up in the upper limit range and blue
diodes light up in the lower limit range.
