This module covers how to perform a fuel pump voltage drop test using PicoScope, including channel setup, probe placement, and use of the math channel feature to calculate and display voltage drop values.

Key topics include:

• Connecting channels to the battery, fuel pump positive, and fuel pump ground terminals
• Using a current probe alongside voltage channels
• Creating a math channel (A minus B) to isolate positive-side voltage drop
• Adding DC average measurements for both positive and negative sides of the circuit
• Building a custom math formula (A minus B plus C) to display total circuit voltage drop on a single screen
