Reset Current Histogram
The reset button will clear the Current histogram, but leave the Training histogram.
Pneumatic Leak
Pneumatic leak is detected by the positioner. The Current Value field shows the leak. The
valve must move (even if it is a very small amount) before the value can be updated. The
Initial Warning and Full Warning limits affect the health bar indicator on the Dashboard. For
example, as the pneumatic leak increase and pass the Initial Warning, the health bar will
begin to turn yellow. As it approaches the Final Warning, the health bar will be completely
yellow.
Adjusting Limits
There are two ways to adjust the settings.
1. Move the scale indicators. The limits can be adjusted by "dragging" each limit
indicator with a mouse click.
2. Use the input boxes. Numbers can be directly typed. Clicking on the up and
down arrows will also change the value.
NOTE: The apply button must be selected for the changes to take affect.
