Southridge High School automotive students recently passed the national certification test for Snap-on digital multi-meters. The students covered the working functions of the meter and how to use it to find voltage, amperage and resistance, and how to use the meter to record voltage readings and compare those reading to a good electrical circuit. The students, taught by automotive instructor Chris Satterfield, then took an online exam provided by Snap-on Tools and NC3, a national certification center. The certification is good for three years.
