Назначение

Измерители параметров электробезопасности электроустановок MI 3394 (далее -измерители) предназначены для

—    воспроизведения напряжения переменного и постоянного тока;

—    измерения тока утечки;

—    измерения электрического сопротивления;

—    измерения сопротивления изоляции;

—    измерения электрической мощности;

—    измерения напряжения переменного тока;

—    измерения силы переменного тока.

Описание

Измерители представляют собой многофункциональные цифровые портативные электроизмерительные приборы.

Принцип работы измерителей заключается в преобразовании входного аналогового сигнала с помощью АЦП, дальнейшей его обработке и отображении результатов измерений на жидкокристаллическом дисплее.

Управление процессами измерений осуществляется при помощи встроенного микропроцессора. Приборы оснащены функцией установки текущей даты и времени.

Результаты измерений могут быть сохранены во встроенной памяти или переданы на внешний компьютер по интерфейсам связи RS-232, USB, Bluetooth, Ethernet.

Управление    измерителями

осуществляется при помощи клавиатуры и сенсорного    дисплея.    На

жидкокристаллическом    дисплее

отображаются    измеряемые    и

воспроизводимые параметры, а также режимы работы.

Основные узлы измерителей: микропроцессор, источник напряжения, источник тока, измеритель тока, преобразователь напряжения, устройство управления, модуль интерфейсов связи, цветной сенсорный ЖК-дисплей, источник питания.

Конструктивно измерители выполнены в виде кейса. Органы управления, индикации, разъемы для питания и измерений размещены на верхней панели.

Для предотвращения несанкционированного доступа винты крепления корпуса измерителей пломбируются специальными наклейками, при повреждении которых остается несмываемый след.

Программное обеспечение

Встроенное ПО (микропрограмма) реализовано аппаратно и является метрологически значимым. Метрологические характеристики приборов нормированы с учетом влияния встроенного ПО. Микропрограмма заносится в защищенную от записи память микропроцессора приборов предприятием-изготовителем и недоступна для потребителя.
