User manual

Purchased with a grant from the MassDevelopment Collaborative Workspace Program.

a type of electronic test instrument which allows observation of constantly varying signal voltages, especially very fast changes in voltage over time. The oscilloscope can show information which a simple multimeter cannot. The display usually shows as a two-dimensional plot of one or more signals as a function of time. Non-electrical signals (such as sound or vibration) can be converted to voltages and displayed.

Safety Considerations:

• Often modern digital circuit voltages measured by an oscilloscope are small, but with any measurement of electricity, one should take care to avoid any potential shock.
• Analysis of circuits from Cathode Ray Tube televisions is extremely dangerous and NOT a beginner’s activity. Thousands of volts are involved.

Certification Process:

Read and view the material at the following links to help you prepare for using the oscilloscope.

• Oscilloscope Guide Very thorough information from the UK with a student in mind
• Oscilloscope Tutorial (PDF) from MIT OpenCourseWare – Electromagnetic Energy: From Motors to Lasers
• Oscilloscope Beginner’s Tutorial (PDF) from University of Nebraska Lincoln Electrical Engineering Shop
• Instructibles Tutorial web page with available download

A glass grinder is primarily used for working with pieces of stained glass, preparing the edges to make them smooth and to help them match the edge of the next mating piece of glass in the pattern. The grinder is water cooled to avoid overheating the glass edges, and is safe to use with care to wear safety glasses and DOES require caution because of the potential for glass breaking.  Always use gentle pressure to grind the edges and take extra care with narrow glass pieces or when grinding near sharp glass points.
