H-46 MOUNTING INSTRUCTIONS

Using the existing Antirotation Lug

1. Drill 3.2 mm (0.125) diameter antirotation

pin hole on vertical centerline 14.3 mm

(0.562) below center of potentiometer

mounting hole.

2. Mount potentiometer shaft counterclock-

wise to obtain minimum resistance or

voltage ratio. This is not necessarily

identical with the mechanical stop.

3. Loosen set screws in knob of dial. Set dial to “0.0” reading.

4. While holding outer ring of dial, position unit lightly against

panel. Tighten knob set screws to potentiometer shaft.

with dial) and lockwasher (supplied

with potentiometer).

3. Turn potentiometer shaft counter-

clockwise to obtain minimum

resistance or voltage ratio. This is

not necessarily identical with the

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.
