Setup and Operation
Charge sampler touches the electroscope:
• Remove the charge sampler from the front of the elec-
troscope and plug it in the top of the apparatus.
• 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.

Introduction
The SF-9069 Electroscope is used for detecting and dem-
onstrating 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 electro-
scope, 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.
Additional Equipment Recommended
• Banana plug connectors to ground the electroscope.
• Classic electrostatic materials kit (SF-9068) for trans-
ferring charge to the capacitor plates.

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