Is it possible to add a feature to the guages that would allow them to be set up as an alarm.  When testing we cannot watch everything but a visual that gets our attention is very handy and can save an engine.   Peripheral vision can be used to notice a blink or color change.   Maybe the three ranges on the guage setup  box could have a check box to used as an alarm.    If the valve goes into that range the guage would blink or change background color.     That would signal the operator to quickly check to see what is going on.
