Many industrial professionals assume that equipment failure happens due to catastrophic events. While sudden failures can occur, those focused on quality control must also remain aware of equipment calibration drift. It happens in tiny increments and often over prolonged periods, making it much more challenging to detect unless problems result.
Reliability is one of many calibration benefits because it means that the measurements taken by an instrument align with traceable reference standards within stated tolerances. When an instrument is out of calibration, that does not necessarily mean it has completely failed. The more likely outcome is that the instrument can no longer produce accurate measurements for operational requirements. This matter can become a supply chain risk, especially because many companies rely on outside suppliers that use calibrated instruments in the production or installation of components.
Learn why invisible machine drift is difficult to pinpoint and how industrial leaders can reduce supply chain vulnerability.
Reputational Risks Are Possible
When consumers learn of product recalls, they primarily think of the associated brands and rarely recognize or acknowledge how a third-party supplier may have caused the issue. This reality means that companies affected by equipment calibration drift may experience adverse reputational effects even if they never owned or operated the out-of-calibration measuring tools.
In one example, an automaker recalled a vehicle after a calibration error that could cause the air bag system to fail to deploy during a crash, potentially leaving a front-seat passenger unprotected. The issue impacted 63 models. Although the manufacturer was unaware of accidents caused by this problem, it is easy to imagine that some people who heard the news believed the brand does not take safety seriously enough.
Some of the affected models also had recalls issued for other problems before the supplier learned of and reported the calibration error. Contractually obligating suppliers to keep measuring equipment calibrated is one way to reduce supply chain vulnerability. If those entities know that machine drift directly affects their business potential, they may feel more motivated to prevent it.
One option is to work with an accredited calibration lab. These facilities ensure measurement equipment aligns with industry standards, which can help clients prepare for inspections or demonstrate readiness. Taking such proactive steps protects suppliers’ and brands’ reputations.
Equipment Calibration Drift Interferes With Life-Altering Decisions
Medical equipment, from microscopes to radiographic equipment, requires calibration to deliver accurate results. Reliability is essential because patients’ lives depend on the provided data, which could contain errors if machines are out of calibration. Equipment calibration drift could cause healthcare providers to either miss conditions or recommend inappropriate tests and treatments. Both issues cause supply chain problems by wasting time and resources and simultaneously delaying the necessary actions that could save or improve lives.
Hospitals and similar settings invest in routine maintenance for medical equipment because calibration prevents downtime and incorrect information. Keeping the machines working well affects patients, on-site staff and support personnel who may travel between facilities to deliver specialized care, such as medical imaging expertise. Unexpected machine outages cause supply chain bottlenecks, especially when traveling employees don't learn about problems until they reach their destinations. Those outcomes stop them from spending their time elsewhere and serving other patients.
Those waiting for diagnoses that require specialized equipment also suffer because any delays can be extremely stressful and cause people to imagine the worst-case scenarios, even if they lack data to support those potential outcomes.
Entire Industries Experience Calibration Benefits
Many discussions center on how essential the agriculture industry is to the world's food supplies. It has also been disrupted recently by precision farming and the associated equipment. Because the machines now have sensors, cameras and other advanced components, owners need to routinely schedule service calls for calibration and other checks.
Research indicates that the locations where these technicians are in the highest demand have approximately three to seven professionals per 100 farms, illustrating how easily they could receive overly heavy workloads. Such a situation could degrade quality control, especially if those calibrating the machinery do not have enough time for conscientious efforts.
However, the more likely scenario is that farmers who request calibration appointments will need to wait longer for them. That delay creates supply chain vulnerabilities, especially if agricultural workers cannot confidently use equipment that they believe is out of calibration. In the agricultural industry, equipment often requires specialized service.
Across sectors, some executives are addressing the need for calibration assistance by expanding the skills of their in-house maintenance teams. That approach creates the need for highly accessible and thorough training programs developed for workers who do not ordinarily perform calibration, such as those handling other maintenance tasks.
Invisible machine drift spans beyond routine maintenance. However, it can also fall under that sector. More frequent checks increase the likelihood that someone detects an abnormality before it causes problems throughout the supply chain.
Reduce Supply Chain Vulnerability Today
Calibration-related matters contain many supply chain lessons. Although keeping equipment calibrated cannot solve all relevant issues, it reduces far-reaching risks that impact customers and their lives. This reality means professionals should treat calibration as more of a maintenance matter and view it as a company safeguard.
