Why should TMDE be checked prior to use?

Checking TMDE (Test, Measurement, and Diagnostic Equipment) prior to use is crucial to ensure that the device is within its calibration period and remains undamaged. Calibrated equipment provides accurate measurements, which is essential for quality assurance in any operational environment. If a device is out of calibration, it could lead to faulty measurements that compromise the integrity of tests or assessments performed. Furthermore, an undamaged device is necessary to maintain safety and reliability during operations; any physical damage could lead to malfunction or inaccurate results.

Addressing operational readiness or compliance with safety regulations, while important, are secondary to having appropriately calibrated and undamaged equipment. Similarly, user familiarity with the equipment, though beneficial for effective use, does not directly relate to the fundamental capability of the TMDE to provide accurate and safe measurements. Thus, ensuring the calibration status and physical condition of the TMDE is essential for its reliable operation.
