Human estimation of quantities is usually pretty unreliable. There is an entity known by the psychologists as JND or just noticeable difference. This is approx 25%.
If we are asked to match say two masses just using our sense of feel, then an agreement within 25% is to be expected. Similarly with heat and the brightness of a light.
A device for measuring depth of water by sending pressure waves down from the surface and recording the time until the echo returns from the bottom.
Occupations are least likely to involve use of a computing device on a day-to-day basis could include:cookswaitress in small resturantorderly in a hospitaltransportation worker who transports patients between hospital departmentscleaning staffmaintenance workers
A Resistance Temperature Detector (RTD) is a device with a significant temperature coefficient used as a temperature measurement device, usually by passing a low-level current through it and measuring the voltage drop. To calibrate, refer to the manual for specific instructions. In general the steps include placing the reference probe and the UUTs in the temperature source in close proximity to one another, connecting the leads to the readout, and measuring the reference probe and determining the temperature.
Question: Why is computer technology important?Answer: Without computer tecnology, I wouldn't be able to type this, would I?
an end device
The least count of a voltmeter is the smallest measurable change in voltage that the device can detect. It is determined by the resolution of the display and the sensitivity of the measuring components. It is important for accurate voltage measurement.
by the least accurate measure
A scale is a measuring device commonly used to measure mass. It can be digital or mechanical and is designed to give an accurate reading of an object's weight in units such as grams or kilograms.
The least accurate system for measuring medicine is likely the household teaspoon or tablespoon. These are not standardized units of measurement, leading to variation in dosage. It is more reliable to use a calibrated measuring spoon or a syringe provided with the medication.
An atomic clock the most accurate time measuring device. It uses an electronic transition frequency in the optical, ultraviolet, or microwave region of the electromagnetic spectrum of atoms.
measuring devices are really important so that you can give accurate information regarding measurements.
A laser measuring device is useful in most any construction job as it is a very accurate tool. It is useful for remodeling jobs as well as upgrades in homes.
The most essential element in a voltage measuring device is a very high impedance. This prevents the device interfering with the measurement.
A graduated cylinder with a capacity of at least 75cm3 would be the most accurate for measuring 75cm3 of water. This is because graduated cylinders are designed for precise volume measurements and have markings that allow for accurate readings.
An extremely accurate device used as an instrument for measuring the distance between two points. Often used in machining.
Sensitivity is the ability of a measuring device to detect small differences in the quantity being measured. It refers to how responsive the device is to changes in the input signal, allowing it to capture even subtle variations. A highly sensitive measuring device is able to provide accurate readings even in the presence of minimal changes in the measured quantity.
The sundial device was and is a very accurate tool of measuring units of time. The sundial devices uses the sun to pinpoint exactly what time it is because of where the shadow falls.
