The Least Count error is the error associated with the resolution of the instrument.

Measured values are good only up to this value.

The Smallest value that can be measured by the measuring instrument is called its least count.

★ It is an instrumental or random error related with the precision, i.e. limit are resolution of a measuring instrument.

★ Least count is the smallest value that can be measured by Measuring instrument.

★ Least count error is the error associated with the resolution of the instrument.

$\orange{\bold{\underline{\underline{Precautions\:of\:Least\: Count \: Errors \: :}}}}$

• The Least count error occurs with both systematic and random errors.

• Instruments of higher precision can reduce the least count error.

• By repeating the observations and taking the arithmetic mean of the result.

• The mean value would be very close to the true value of the measured quantity.
