Функция преобразования измерительного канала имеет вид ¯ = 74, 87 + 1, 86. По этой формуле рассчитаны значения ¯ в шестом столбце таблицы. Абсолютные и относительные погрешности в каждой точке вычисляются по формулам
= − ¯ ; |
= |
|
|
100 %. |
|
||||
|
|
Как видно из таблицы, наибольшая относительная погрешность = 0, 32 % Наибольшая по модулю абсолютная погрешность преобразования = 7, 0 наблюдается в точке = 30, таким образом, приведённая погрешность равна
= |
|
| | |
= |
7, 0 |
|
|
100 = 0, 19 % . |

4. Задания для самостоятельной работы
Задание 1. При измерении активного сопротивления резистора были произведены десять равноточных измерений, результаты которых приведены в таблице 4.1. Предельная относительная погрешность средства измерения также указана в таблице 4.1. Оцените погрешности измерения и запишите результат измерения для доверительной вероятности 0, 95.

Задание 3. Оцените погрешность прямого однократного измерения напряжения на сопротивлении , выполненного вольтметром класса точности с верхним пределом измерения и внутренним сопротивлением . Известно, что дополнительные погрешности показаний вольтметра из-за влияния магнитного поля и температуры не превышают соответственно и основной погрешности прибора. Исходные данные задачи приведены в таблице 4.3.

Задание 4. К источнику питания подключены три нагрузки, обозначенные на схеме как 1, 2, 3. Токи, измеренные в цепи каждой нагрузки равны 1, 2, 3, а измеренное напряжение источника питания равно .
Определите мощность каждой нагрузки и значение абсолютной погрешности
28
этой мощности. Оцените суммарную мощность, потребляемую от источника питания и её погрешность. Классы точности амперметров, включенных в цепях нагрузок, соответствуют 1, 2, 3, а предельные значения их шкал – 1, 2,3. Класс точности вольтметра , а предельное значение шкалы – . Все данные приведены в таблице 4.4.
