Units:
A text entry box in which the user can enter an engineering units string comprised of up to 8
characters. This units string will be appended to all locations in the gauge window that display the
designated parameter’s current value.
Parameter:
The designated parameter whose value is to be reflected on the gauge. Note that only
scanned parameters may be displayed in Dashboard gauges (refer to section 4.1 for a discussion of
scanned parameters).
Multiplier:
The multiplier value is a floating-point number that is used to scale the raw value of a
parameter. As its name suggests, the multiplier value is multiplied by the designated parameter’s current
raw value in order to calculate the gauge’s indicated value. Negative values can also be used if desired.
Min Value:
The gauge’s minimum indicated value. Negative values can be used if desired (e.g. if a
negative Multiplier attribute is used to generate a negative indicated value). Not all gauges allow
adjustment of the min value.
Max Value:
The gauge’s maximum indicated value. Similar to the Min Value attribute, negative values
can be used if desired. Indicated value characteristics can even be inverted by setting the Max Value
attribute to a value less than the Min Value attribute.
Update Button:
Clicking the update button will apply the current configuration attribute settings to the
gauge. Note, however, that simply updating the gauge’s current display properties does not write these
settings to the interface card’s file system. To save the current configuration of all the gauge windows to
the file system, the Dashboard tab’s “submit” button must be selected (refer to section 6.3.4).
Current Value:
The current indicated value of the designated parameter is numerically displayed with
the configured Units string at the bottom of each gauge window.
The following is a summary of the different available gauge types:
Gauge:
Refer to Figure 18. This type of
meter implements a rotary dial-type display
format. The indicated value and units are
shown numerically on the face of the gauge,
and via the red indicator needle. The yellow
needle shows the previous indicated value,
thereby providing a simple historical
reference. The “Min Value” attribute is not
configurable; this gauge always starts at 0.
BarGraph:
Refer to Figure 19. This type of
meter implements a linear bar graph display
format. Hovering the mouse pointer over the
red portion of the graph pops up a tooltip
which displays the current indicated value
and units.
