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.
