-  * **Description**:
+=== Description ===
-  * **Purpose**:
-  * **Source**:
+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.
-  * **Approximate Cost**:
+Free advice:  DO NOT buy a $5 multimeter.  Students have had difficulty with those inexpensive meters in the past.
+=== Purpose ===
+Students will be taught how to use a multimeter to troubleshoot electrical circuits, and to verify important fundamental principles of DC circuits.
+=== Approximate Cost ===
+A $15, multifunction multimeter is fine.  Don't buy the cheap $5 multimeters.
+=== Sources ===
+  * Sparkfun sells a decent, low cost {{https://www.sparkfun.com/products/12966|digital multimeter}} for $15 plus shipping. The multimeter has all the functions necessary for class, but it is not auto-ranging.
+  * Amazon sells a {{https://www.amazon.com/INNOVA-3320-Auto-Ranging-Digital-Multimeter/dp/B000EVYGZA/|digital multimeter}} for $24 plus shipping. Another {{https://www.amazon.com/Multimeter-Crenova-MS8233D-Auto-Ranging-Multimeters/dp/B00KXX2OYY/|less expensive}} multimeter is available for $18. Either multimeter will work for the class.
+  * The local Fry's store has a low-cost, {{http://www.frys.com/product/6449882|digital multimeter}} for $12. Better multimeters are autoranging, which makes measurement easier. But, the multimeter shown will work well for this course.
