The reading here is 3.

A stopwatch used to time a race might resolve down to a hundredth of a second, its least count. The reading is 7.

Basically it is a screw with an accurately constant pitch the amount by which the thimble moves forward or backward leash one complete revolution. Recording the result of your micrometre measurement Let us say you take a reading with an object between the jaws of a vernier calipers vernifr you see the following: In figure 5 above, the first significant figures are taken as the main scale reading to the left of the vernier zero, i. Khurram Shaukat Memon August Next Question An internal auditor in a trust at the time of audit may have to count the cash p More Questions Like This.

Unfortunately, the answer you are trying to submit has already been added. When it is about differentiating it between vernier caliper and micrometer screw gauge based on their structures, one can easily distinguish between them as Vernier caliper is a gun-like equipment, whereas micrometer vernjer an axe-like equipment. Ir ;ve also always had an interest in making games. The first significant figures are read immediately to the left of the zero of the vernier scale and the remaining digits are taken as the vernier scale division that lines up with any main scale division.

Here is a nice vernier calipers applet. Therefore the reading is In figure 6 the zero and the ten on the vernier scale both line up with main scale readings, therefore the reading is My Question is New. The least count error is the error associated with the resolution of the instrument. Least count error [ edit ] The smallest value that can be measured by the measuring instrument is called its least count.

In figure 4 above, the first significant figures are taken as the main scale reading to the left of the vernier zero, i. What is the least count of Vernier and Micrometer? Let our CV writing experts help you.

The micrometer screw gauge The micrometer screw gauge is used to measure even smaller dimensions than the vernier callipers. The remaining two digits are taken from the vernier scale reading that lines up with any main scale reading, i. In figure 14 the 0. Least count of an instrument is one of the very important tools in order to get accurate readings of instruments like vernier caliper and screw gauge used in various experiments.


If the physical count exceeds the system generated report – What are the possible ways to find out why? These instruments have a main scale in millimetres and a sliding or rotating vernier scale.

Zero error can be of two types, positive zero error and negative zero error, if the vernier scale is to the left of the main scale than it is negative zero error and when the vernier sale is on the right side of the main scale than it is the positive zero error.

The screw clamp may then be tightened to ensure that the reading does not change while the scale is being read. Where does hard drive save the bad sector fount number? Note that an additional half scale division 0. The smallest value that can be measured by the measuring instrument is called its least count. The main scale is calibrated in millimeters.
