H-506 MOUNTING INSTRUCTIONS 1. Drill 2.0 mm (.0787 in.) diameter anti-rotation pin hole on vertic centerline, 9.5mm (.375 in.) below center of potentiometer mounting hole. 2. Mount potentiometer in panel with nut and lockwasher supplied with the potentiometer. 3. Turn potentiometer shaft counterclockwise to obtain minimum resistance or voltage ratio. This is not necessarily identical with mechanical stop. 4. Loosen set screws in knob of dial. Set dial to "0.0" reading. 5. While holding outer ring of dial, position unit lightly against panel. Tighten knob set screws to potentiometer shaft.
