Multimeter & Oscilloscopes

Safety Precautions & Procedures

• If you are not confident, testing a certain circuit, do some research before beginning tests.

• Never assume a meter is working properly. Use a known voltage source to verify.

• Before starting any measurement activity, you should check the multimeter for continuity. To do this, connect its leads and confirm that it reads zero or close to zero.

• The range or function switch should only be changed when the leads are disconnected from the circuit.

• Use test leads with minimal exposed metal at the tip to protect against electrical shorting
