Advanced Multimeter Techniques for Heating Tune‑Up Success is a focused, technician‑driven training session designed to elevate diagnostic accuracy and confidence during heating system tune‑ups. Using the Fieldpiece SC‑series meters as the primary diagnostic platform, this class teaches participants how to apply advanced multimeter functions to verify electrical health, identify performance‑limiting faults, and ensure safe, efficient system operation.

Technicians will learn how to interpret real‑world readings, validate component performance, and apply measurement strategies that reduce callbacks and speed up troubleshooting. The session emphasizes hands‑on practice with live circuits, proper test‑lead placement, and safe measurement habits that align with industry best practices.

Key Learning Outcomes
Participants will learn to:

• Perform precision voltage, amperage, and resistance tests on heat strips, sequencers, contactors, and blower circuits.
• Use inrush, microamp, and capacitance functions to evaluate ignition systems and motor performance.
• Apply advanced continuity to verify control circuits and safety switches.
• Interpret multimeter readings to identify failing components before they cause system failure.
• Integrate Fieldpiece JobLink features in a structured heating tune‑up workflow.
• Follow safe, repeatable testing procedures that protect both the technician and the equipment.
