Alternating Current & Direct Current Metrology Course

Course Description:

AC/DC Metrology develops the knowledge and professional judgment required to generate, measure, evaluate, and report direct- and alternating-current electrical quantities.

The course is organized around measurement principles rather than individual instruments. Participants begin by examining voltage, current, resistance, frequency, waveform characteristics, and the differences between steady-state and time-varying signals. They then evaluate how source impedance, input impedance, burden voltage, lead resistance, bandwidth, frequency response, distortion, noise, grounding, shielding, and environmental conditions influence observed values.

Representative systems include:

• Digital multimeters
• Multifunction calibrators
• Precision voltage sources
• Current sources and shunts
• Resistance standards
• Transfer standards
• Thermal converters
• Oscilloscopes
• Frequency counters
• Power analyzers
• Automated calibration systems

The course also addresses test-point selection, equipment configuration, safe connections, warm-up and stabilization, specification interpretation, measurement assurance, uncertainty, decision rules, and reporting.

The objective is not merely to teach technicians how to connect a calibrator to a meter. It is to develop professionals capable of understanding the complete electrical measurement system and determining whether the resulting data are fit for the intended use.
