If this attribute is set, the portion of the single-bar below this limit will be painted using the pen color specified by the LOW PEN attribute. On a monochrome monitor, a line is drawn at the LOW LIMIT. To have LOW LIMIT appear on the bar, LOW LIMIT must be greater than or equal to MINIMUM and must be less than or equal to MAXIMUM, and must be less than or equal to HIGH LIMIT.
The value of LOW LIMIT acts as a trip point between the alarm ranges on the single-bar. It is the trip point between the middle range and the low range. The programmer must use HIGH LIMIT, LOW LIMIT, ALARM RANGES, and ALARM TYPE to specify the alarm behavior of the single-bar.
