Introduction

The SF-9069 Electroscope is used for detecting and dem­onstrating static charge. When the electroscope is
charged, the lightweight conductive rod rotates to indicate
the magnitude of the charge. The apparatus includes a
Charge Sampler for transferring charge to the electro­scope, two Capacitor Plates (5.6 cm dia) for testing
charges without depositing them on the electroscope and
an insulating handle for carrying the capacitor plate. The
electroscope shield ring is 15 cm in diameter.

Setup and Operation

Charge sampler touches the electroscope:

• Remove the charge sampler from the front of the elec­troscope and plug it in the top of the apparatus.

No charge

to

GND

• Use a banana plug connector to ground the electroscope.

• Attach the insulating handle to a capacitor plate.

• Load a charge onto the capacitor plate from a charged
item such as a PVC rod rubbed vigorously with a
wool cloth.

Additional Equipment Recommended

• Banana plug connectors to ground the electroscope.

• Classic electrostatic materials kit (SF-9068) for trans­ferring charge to the capacitor plates.

The electroscope can also be charged using a kilovolt
power supply.

➤ NOTE: The electroscope can be discharged at
any time by using the capacitor plate and handle to
make contact between the shield ring and the
charge sampler.

• Transfer the charge to the electroscope by touching
the charged capacitor plate to the charge sampler.

Charge sampler does not touch the electroscope:

• Replace the charge sampler with the second capaci-

tor plate and ground the electroscope completely.

• Induce a charge by holding the charged capacitor

plate near the second capacitor plate.
