Which calibration term refers to applying a calibration signal of low voltage to all amplifiers using the initial study values?

• A. Montage
• B. Physiologic
• C. All channel
• D. Signal

Answer: (A)

Montage calibration focuses on the way channels are configured and tested together. When you apply a known, low-voltage calibration signal to all amplifiers using the initial study values, you’re checking the entire channel set as it’s arranged in the montage—ensuring that each channel scales correctly relative to the chosen reference and grounding scheme. This keeps gains and offsets consistent across all leads and confirms the system is set up as intended for the study. Physiologic calibration would use actual bodily signals rather than a standard test signal, so it isn’t about verifying the uniform response of all amplifiers across the montage. All-channel and signal are more generic terms; montage specifically ties the calibration to the configured channel arrangement and reference framework used during recording.
