designated register’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 filesystem. To save the current configuration of all the gauge windows to the filesystem, the Dashboard tab’s “submit” button must be selected (refer to section 10.11.4).

Current Value: The current indicated value of the designated register 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 54. 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 The yellow needle shows the previous indicated value, thereby providing a simple historical reference.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.
