and
D.FLSH
are enabled, when the incoming signal is below the bottom end of the bar
display, the first LED and digital display flash at a 1 Hz rate, indicating an underrange condi-
tion. When the process signal exceeds the full scale value, the top LED and digital display
flash at a 1 Hz rate, indicating an overrange condition.
If the underrange or overrange condition exceeds the displayable range, the digital display will
show
