Measuring equipment
A measuring means according to the standard DIN 1319 -2 a measuring device , a measurement device , a normal , tool or reference material or to perform a task in the measurement technique is necessary. Devices for counting (e.g. in digital measuring technology ), for calibration , adjustment or testing are also measuring equipment. The resources also include accompanying documents or programs.
The quality of the measuring equipment is ensured through regular measuring equipment monitoring.
Measuring equipment for tests is also referred to as test equipment .
features
In the following, the term measuring device is used as a collective term for measuring device, measuring device, measuring standard and standard. The following features are to be observed (according to):
- Measuring range
- Static behavior: See characteristic curve , sensitivity
- Dynamic behavior in the event of a sudden change in the value of the input variable: Setting duration: The time that elapses after the change until the value of the output variable remains permanently within specified limits; see also step response .
- Response threshold
- Resolution: See resolution (physics) , resolution (digital technology)
- Hysteresis : A feature of a measuring device that consists in the fact that the value of the output variable, which is set at a certain value of the input variable, depends on previous values of the input variable.
- Retroactive effect
- Drift: Slow change in the value of a metrological feature of a measuring device.
- Meter deviation
- Error limits
