“Exclamation Point” Display
DS007970-9
LEDs light up as illustrated with the upper lit LED indicating the actual input voltage. The display appears to increase resolution and provides an analog
indication of overrange.
Indicator and Alarm, Full-Scale Changes Display from Dot to Bar
DS007970-10
*
The input to the Dot-Bar Switch may be taken from cathodes of other LEDs. Display will change to bar as soon as the LED so selected begins to light.
