4. Настройка

4.1 Установка аккумулятора

The KKM828 requires three AA batteries for operation. Ensure the device is powered off before installing or replacing batteries.

  1. Найдите крышку батарейного отсека на задней панели устройства.
  2. Open the battery compartment cover by sliding or unscrewing it (if applicable).
  3. Insert three AA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
  4. Плотно закройте крышку батарейного отсека.

4.2 Включение/выключение питания

To power on the device, rotate the function dial from the "OFF" position to any desired measurement function. To power off, rotate the dial back to the "OFF" position.

5. Инструкция по эксплуатации

5.1 Функции мультиметра

The KKM828 offers a comprehensive range of multimeter measurement capabilities. Always connect test leads correctly to the appropriate input jacks (e.g., COM, VΩHz, mA, 10A) for the selected function.

  • Переменный / постоянный токtagд Измерение: Rotate the dial to the 'V~' or 'V=' position. Connect test leads in parallel with the circuit.
  • Измерение переменного/постоянного тока: Rotate the dial to the 'mA~', 'mA=', '10A~', or '10A=' position. Connect test leads in series with the circuit.
  • Измерение сопротивления: Rotate the dial to the 'Ω' position. Ensure the circuit is de-energized before measuring resistance.
  • Измерение емкости: Rotate the dial to the 'mF' position. Discharge capacitors before measurement.
  • Измерение частоты и коэффициента заполнения: Rotate the dial to the 'Hz%' position.
  • Диодный Тест: Rotate the dial to the 'Diode' position. Connect leads across the diode to check forward voltagе падение.
  • Тест на непрерывность: Rotate the dial to the 'Continuity' position. The device will beep if resistance is below approximately 50Ω.
