Measurement Device

A Measurement Device is a device that performs measurement tasks to determine properties of entities through standardized processes.

Context:
- It can (typically) produce Measurement Values with specified measurement accuracy.
- It can (typically) require Device Calibration for reliable measurements.
- It can (typically) follow Measurement Standards for consistent results.
- It can (often) generate Measurement Records through data acquisition.
- It can (often) support Measurement Unit conversion for different scales.
- It can (often) require Regular Maintenance for accuracy preservation.
- ...
- It can range from being a Simple Measurement Device to being a Complex Measurement Device, depending on its measurement complexity.
- It can range from being a Single-Parameter Device to being a Multi-Parameter Device, depending on its measurement scope.
- It can range from being a Manual Measurement Device to being an Automated Measurement Device, depending on its operation mode.
- It can range from being a Contact Measurement Device to being a Non-Contact Measurement Device, depending on its measurement method.
- It can range from being a Low-Precision Device to being a High-Precision Device, depending on its measurement precision.
