Field Adjustment Knob
The Field Adjustment Knob is located on the side of the Hi-lume Premier 0.1% Constant Voltage Driver (L3D0)
enclosure. This feature enables the customer to tune the lowest light output achieved during normal operation. An
example of this scenario is shown in the image below. Adjusting the Field Adjustment Knob of the lower light
output driver minimizes the light output difference and sets the low-end light level at 0.1%. This feature
only needs
to be used in cases of mismatched loads that are separately controlled by 2 or more units.
The Field Adjustment Knob cannot fix light level mismatch among loads on the same driver. For example, two
homeruns of different wattage. For increasing the minimum light output of all the drivers in a space, please use
the control's low-end trim feature. Using the Field Adjustment Knob for this purpose will degrade On / Off transition
performance.

Steps:
1. Set the control to low-end and turn all knobs fully
counter-clockwise
2. Identify the driver with the lowest light output
3. Turn the knob clockwise until the light output
