Introduction

The AP-8212 Millikan LED Light Source is designed for use with the AP-8210 Millikan Oil Drop Apparatus.
You can use the AP-8212 Millikan LED (light emitting diode) Light Source to replace the Light Source Assem­bly on the AP-8210. The Millikan LED Light Source is brighter than the original light source on the AP-8210,
and the brightness of the LED Light Source is adjustable. The very long expected life span of the LED means
that the LED Light Source should never need replacement. (NOTE: If the LED does fail, do not attempt to
replace it. Contact PASCO about returning it for repair.)

The Millikan LED Light Source includes the LED assembly and four screws for attaching the LED assembly to
the base of the AP-8210 Millikan Oil Drop Apparatus. The Millikan LED Light Source uses the same power sup­ply (100 to 240 VAC, 10 VDC, 1 A) as the Light Source Assembly that it replaces. The LED brightness adjust­ment knob is on the top of the LED Light Source. Turn the knob clockwise to increase brightness and
counterclockwise to decrease brightness. Note that when the LED brightness knob is turned fully counterclock­wise, the LED may be completely dimmed or it may still be slightly illuminated.

Caution

If the LED of the Millikan LED Light Source does fail, do not attempt to replace it. The LED is a surface mount
component that is soldered to the printed circuit board inside the light source. Contact PASCO about returning
the Millikan LED Light Source or the entire Millikan Oil Drop Apparatus.

Replacing the Light Source

• Make sure that the power supply is discon­nected from the light source on the Millikan
Oil Drop Apparatus.

• Use a phillips head screwdriver to remove
the four screws from the light source assem­bly.

• Carefully lift the light source assembly off
the base and set it aside.

• Remove the stainless steel spring that sits on
the base under the light source assembly.

• Place the AP-8212 Millikan LED Light
Source on the base with the same orientation
as the light source you removed.

• Use the four small screws provided to secure
the LED Light Source to the base.
