LED Indicators
There are two LED indicators on the Grablink DualBase bracket. The LED A is related to acquisition channel A whereas LED B is related to acquisition channel B.
The LED indicators are built with green LEDs mounted on a right-angled holder that fits beside the bracket.
There are three possible states for the LED indicator: OFF, ON, BLINKING.
