Channel calibration is defined as what?

• A. Adjustment of channel output to meet known values within range and accuracy
• B. Qualitative verification by observation
• C. Introduction of a signal into channels
• D. Movement of core components

Answer: (A)

Channel calibration is the process of adjusting a channel’s output so it matches known reference values across its operating range within the specified accuracy. This makes the instrument’s readings reflect the true process value and ensures reliable, safe measurements. It uses known inputs or reference standards to set the channel’s gain and offset and correct drift or bias. It’s not just observation or qualitative verification, which doesn’t adjust the channel to a standard, and it’s not simply injecting a test signal or moving core components, which relate to testing or mechanical changes rather than calibration.
