Calibration is the comparison of an equipment indication or output against a suitable reference standard under defined conditions. The result helps users understand measurement accuracy and whether the equipment meets selected acceptance criteria.
Open FAQCalibration supports patient safety, clinical confidence, maintenance planning, audit readiness and reliable equipment history by identifying drift in measured or delivered values.
Open FAQOnsite calibration may be possible when the equipment, method, environment, reference standards and approved scope allow it. Some equipment is better handled in a laboratory.
Open FAQCalibration frequency depends on manufacturer recommendations, equipment risk, usage, operating environment, past results, repair history and the hospital's policy.
Open FAQA competent calibration laboratory or authorised service provider can issue a calibration certificate. NABL-accredited certificates apply only when the activity is within the laboratory's approved scope.
Open FAQMeasurement uncertainty expresses the doubt associated with a measurement result. It helps users understand confidence in a result and should be considered with acceptance criteria.
