Guide

1

Inspect scale analog device, which is measured.It marked unit works with this device.On any scale marked numerical values of the measured value, between which there are

*division*without quantitative indicators.The value contained between them is smallest, which can be measured by the instrument.Price*division*device - the smallest value that can be measured with this instrument scale.This lowest price is contained in the smallest scale division of the instrument. 2

get on the scale the next two digital values.It is absolutely not important their order.For example, if a measuring cylinder, by which to m
easure the volume of fluid in ml plotted numerical values of 0, 100, 200, 300, 400, 500, it is possible to take a pair of numbers 0 and 100, 100 and 200 or 400 and 500 or anyanother pair of numbers on this principle.Subtract from the number increases less.

Count

*division between the nearest numerical values on the scale.When counting, note that division is the distance between the two nearest lines of the scale, not the lines themselves.Calculate the price**division*device by dividing the difference between the next two numerical values of the scale to the number of divisions between them.This will be the minimum value of the measured device. 4

example, to find

**price***division*scale voltmeter which measures the voltage in volts, with the numbers 0, 2, 4, 6, 8 and five*division*of the two closest numerical values, perform a sequence of actions.Take the next two numeric values - let it be 4 and 6. Now subtract a larger number of smaller - turn 2. This number is divided by the number of divisions between these values (on the condition it is equal to 5).Get 2/5 = 0.4 volts.Price*division*voltmeter is 0.4 V. Sources:
