What is the typical frequency of calibration for measurement instruments used in clearance?

• A. Calibrate monthly regardless.
• B. Calibrate according to manufacturer instructions; often daily or per batch, with periodic calibration checks.
• C. Calibrate never.
• D. Calibrate only if readings seem wrong.

Answer: (B)

Regular calibration is about keeping instruments trustworthy and results believable for clearance decisions. In clearance work, you follow what the manufacturer recommends for how often to calibrate, and many tools used in the field are set up for daily checks or per batch verification, with more thorough calibrations done on a periodic basis. This approach helps catch drift from temperature changes, wear, or battery effects early, so the readings truly reflect lead levels. Calibrating monthly regardless can miss days or batches where the instrument drifted, especially if it’s used daily. Calibrating never would leave you without a reliable standard to trust the measurements. Calibrating only if readings seem wrong postpones catching drift until it’s already affecting results, which risks false conclusions about clearance needs.
