Full/Span Calibration Procedures are performed every how many days?

• A. 60 days
• B. 15 days
• C. 30 days
• D. 90 days

Answer: (C)

Calibration frequency keeps measurements accurate as instruments drift with use and environment. Full/Span Calibration Procedures check the entire measurement range—from minimum to maximum—so every part of the span aligns with a trusted reference within tolerance. Because drift accumulates gradually, performing these procedures on a monthly cycle catches deviations before they impact field decisions, while still being practical to maintain. Longer intervals risk larger, harder-to-cix drift; shorter intervals would be unnecessarily burdensome for routine use unless the system is subjected to extreme conditions. So, a 30-day schedule best fits the need to maintain reliability without overdoing it, which is why the procedure is performed every 30 days. If the system experiences heavy use or rough conditions, rechecking sooner can be appropriate, but the standard cadence is monthly.
