What is percentage limiting error?
A 0-10A ammeter has a guaranteed accuracy of 1.5% of full scale reading.The current measured by the instrument is 2.5A.Calculate the limitting values of current and the percentage limitting error.
What is Back action error?
If the instrument being used is not calibrated or the instrument contains some error or bugs then reading obtained from such instrument would have some error. Such error arising because of the instruments preceding errors is termed as "Back-action Error".
Why is the use of zero-error necessary in a measuring instrument?
The zero error helps in correcting the misreading you get from any instrument. It helps in maintaining the sensitivity of the instruments.
Why is use of zero error necessary in a measuring instrument?
Zero error is necessary for measuring instruments for measuring accurate results because it helps to check that the instrument which we are using is whether correct or wrong
What are the examples of instrumental error?
If an instrument is indicating a wrong parameter instead of actual. Say the actual pressure is 1 bar but the instrument is reading 1.5 bar is an example of instrumental error.
What exacly is a parallax error?
A parallax error is when the experimenter reads or record incorrect measurement of a quantity.This may happen because he/she does not know how to read the instrument and can be prevented by learning to read the instrument correctly.
What type and source of error when or while using vernier caliper?
The Vernier caliper is an extremely precise measuring instrument Error is almost impossible The error that we must always look out for is the zero error and parralex error.
What causes systematic error?
Improper calibration of the measuring instrument. If the measuring instrument is not at zero prior to measuring the object you will get a systematic error which, is a value either always higher or always lower then the actual value of the object.
What is zero error in vernier caliper?
The zero error of a measuring instrument is the measure that it shows when it should actually be showing zero.
Which is more effective in minimizing instrument error in an experiment?
having a large sample size
When was the vernier caliper invented?
It is the measuring instrument it is invented by verniers its error is very small
What is the difference between an error as a percentage of full scale or an error as a percentage of reading?
Error as a percentage of full scale is established by multiplying the error percentage by the full scale flow. The less you flow through the device the less accurate the reading will be. For that reason, you don't want to get a larger device than you need. Devices with error expressed as a percentage of full scale are most accurate when flowing at full scale.Error expressed as a percentage of reading expresses error as a percentage of what the device is actually flowing. Simply, if a instrument's accuracy is rated to +/-1% of reading an instrument will be accurate to +/-1% of whatever the instrument is flowing. At 100SLPM the instrument will be accurate to within +/-1SLPM, and at 10SLPM of flow the unit will be accurate to within +/-.1SLPM.
