This module covers the practical application of math channels in PicoScope 6.2.1, demonstrated through a voltage drop test on the positive starter circuit of a 2003 Chevy Blazer with a slow crank condition.

Topics include:

• Setting up two channels to measure voltage at the battery and starter solenoid output terminal
• Using the A minus B math channel to calculate voltage drop across the positive starter circuit
• Applying low pass filtering to clean up the waveform
• Adding a measurement with DC average between rulers to quantify the voltage drop reading
