ME 120

• Description: A multimeter is an instrument used to measure electrical resistance, voltage, and current. Each students is required to have a digital multimeter for this class. We recommend purchasing a modestly low-cost meter in the range $15 to $35 for this class. A $15 multimeter is perfectly adequate. A $5 multimeter may work, but we have had difficulty with such inexpensive meters in the past. Lab technicians, electricians and engineers often use multimeters costing $200 or more, but that level of multimeter is not necessary for this class.

Students purchasing multimeters on-line should consider pooling their orders to get volume discounts (for 10 or more) and to reduce shipping costs.

• Purpose: Students will be taught how to use a multimeter to troubleshoot electrical circuits, and to verify important fundamental principles of DC circuits.
• Source: Sparkfun sells a decent, low cost digital multimeter for $15 plus shipping. The multimeter has all the functions necessary for class, but it is not auto-ranging.

Amazon sells a low-cost {http://www.amazon.com/INNOVA-3310-Hands-Free-Digital-Multimeter/dp/B000GKEXWA/ref=sr_1_8?s=automotive&ie=UTF8&qid=1411583365&sr=1-8&keywords=digital+multimeter|multimeter}} for $20 plus shipping. This multimeter will work for the class. The local Fry's store has a low-cost, digital multimeter for $20. Better multimeters are autoranging, which makes measurement easier. But, the multimeter shown will work well for this course.

• Approximate Cost: $15
