What is the significance of the least count of the measuring device?
You will learn a great deal about laboratory apparatus and the reading of values off of analogue and digital devices by reading... http://www.engr.mun.ca/~cdaley/1000/measurem.htm "Usually" in Freshman physics, "we" will tell students that the reading "ab.cde" is accurate to one unit in the last place (the e place in this case). It's a "rough" rule and subject to the items discussed in the link I suggested. -Fred
What is the importance of the measuring instruments in process control?
Process control is all about controlling a chemical process or running machinery. Process Control can be in Manual or Automatic, continuous or discrete. In any case the measuring instrument, generally a transducer, gives the real time status of the variable that we propose to control. This could be an Analogue value in milliamps or voltage or a digital on off status. Unless we measure the value to a precision needed in our control system, we cannot change the output of the system manually or in automatic, as required to keep the process in the required state.
How are measuring instruments calibrated?
Calibration is a comparison between a known measurement (the standard) and the measurement using your instrument. Typically, the accuracy of the standard should be ten times the accuracy of the measuring device being tested. However, accuracy ratio of 3:1 is acceptable by most standards organizations.Calibration of your measuring instruments has two objectives. It checks the accuracy of the instrument and it determines the traceability of the measurement. In practice, calibration also includes repair of the device if it is out of calibration. A report is provided by the calibration expert, which shows the error in measurements with the measuring device before and after the calibration. Source : Why Calibration of Your Measuring Instruments is ImportantIn general use, calibration is often regarded as including the process of adjusting the output or indication on a measurement instrument to agree with value of the applied standard, within a specified accuracy. Instrument calibration is one of the primary processes used to maintain instrument accuracy. Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range.Calibrations are performed using only a few calibrators to establish the correlation at specific points within the instrument’s operating range. While it might be desirable to use a large number of calibrators to establish the calibration relationship, or “curve”, the time and labor associated with preparing and testing a large number of calibrators might outweigh the resulting level of performance.Third Party Inspection & Calibration Services Dubai,Abu Dhabi,UAE is the best Calibration Services Provider in UAE.

Why are significant figures important when reporting measurements?
When reporting measurements, you want to express the reading as best you can without overstating what the reading is. That's why you include only one uncertain digit (the last digit) in recording a measurement. "Tell as much truth as you can without reporting more than you really know."
WHAT IS THE LEAST count of a measuring instrument?How it is obtained?
LEAST count of a measuring instrument IS THE LEAST VALUE OF A PHYSICAL QUANTITY WHICH CAN BE MEASURED USING IT. It is obtained by dividing one main division by total no of divisions.
What is the name of the instrument which measures blood pressure?
A sphygmomanometer, blood pressure meter, blood pressuremonitor, or blood pressure gauge is a device used to measure blood pressure. To measure your blood pressure at home, you can use either an aneroid monitor or a digital monitor. Choose and bp meter online the type of monitor that best suits your needs. Digital monitors have either manual or automatic cuffs. The blood pressure reading flashes on a small screen.Measuring your blood pressure at home and keeping a record of the measurements will show you and your doctor how much your blood pressure changes during the day.
