- - devices with different scales.
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.
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.
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.
