MultiRAE Pro is exposed to calibration gas and readings are adjusted to certified gas concentration during what?

• A. Full / Span Calibration
• B. Zero Adjustment
• C. Daily calibration
• D. Temperature calibration

Answer: (A)

Calibrating to a known gas concentration tests how well the instrument’s response matches a known standard across its measurement range. When you expose the detector to a calibration gas with a certified concentration and adjust the readings to that value, you’re performing a full or span calibration. This step sets the sensor’s span so readings reflect actual concentrations. Zero adjustment would only correct the baseline at zero and doesn’t set the span, while temperature calibration deals with environmental effects, not the gas concentration itself. Daily calibration is a routine check, but the action described specifically defines the full/span calibration.
