  2. Calibration - Wikipedia

    en.wikipedia.org/wiki/Calibration

    As an example, a manual process may be used for calibration of a pressure gauge. The procedure requires multiple steps, [ 12 ] to connect the gauge under test to a reference master gauge and an adjustable pressure source, to apply fluid pressure to both reference and test gauges at definite points over the span of the gauge, and to compare the ...

  3. Measurement system analysis - Wikipedia

    en.wikipedia.org/wiki/Measurement_system_analysis

    Common tools and techniques of measurement system analysis include: calibration studies, fixed effect ANOVA, components of variance, attribute gage study, gage R&R, [1] ANOVA gage R&R, and destructive testing analysis. The tool selected is usually determined by characteristics of the measurement system itself.

    For example, the K3/K4 section would maintain Frequency counter, Oscilloscope, Synthesized Signal Generator and power sensor. While K1/K8 would maintain digital multimeter, high voltage probe and resistance standards. Lastly K5/K6 would deal with truck scales, pressure gauges, optics and micrometers. The sections are as follows:

  5. Pressure measurement - Wikipedia

    en.wikipedia.org/wiki/Pressure_measurement

    Gauge pressure is zero-referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. A tire pressure gauge is an example of gauge pressure measurement; when it indicates zero, then the pressure it is measuring is the same as the ambient pressure.

  6. Tire-pressure gauge - Wikipedia

    en.wikipedia.org/wiki/Tire-pressure_gauge

    A tire-pressure gauge, or tyre-pressure gauge, is a pressure gauge used to measure the pressure of tires on a vehicle. Proper tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity. Tire gauges come in various types, including analog, digital, and dial gauges, each offering different features and accuracy levels.

  7. Calibration curve - Wikipedia

    en.wikipedia.org/wiki/Calibration_curve

    A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

  8. Metrology - Wikipedia

    en.wikipedia.org/wiki/Metrology

    Calibration laboratories are accredited and provide calibration services to industry firms, which provides a traceability link back to the national metrology institute. Since the calibration laboratories are accredited, they give companies a traceability link to national metrology standards.

  9. Mercury pressure gauge - Wikipedia

    en.wikipedia.org/wiki/Mercury_pressure_gauge

    An open (differential) mercury pressure gauge. A mercury pressure gauge is a type of manometer using mercury as the working fluid. The most basic form of this instrument is a U-shaped glass tube filled with mercury. More complex versions deal with very high pressure or have better means of filling with mercury.
