4. Поставување
4.1 Инсталација на батерија
- Осигурајте се дека мерачот е исклучен.
- Пронајдете го капакот на преградата за батерии на задниот дел од мерачот.
- Користете шрафцигер за да ги олабавите завртките и да го отстраните капакот.
- Вметнете нова батерија од 9V, почитувајќи го точниот поларитет (+ и -).
- Вратете го капакот на преградата за батерии и прицврстете го со завртката/шрафовите.
4.2 Поврзување на тест кабли
- За волtage, resistance, and frequency measurements, insert the black test lead into the COM терминал.
- Вметнете го црвениот тест одвод во VΩHz терминал.
- For specific 2-channel measurements or other functions requiring a second input, refer to the operating instructions for connecting to the CH2 терминал.
- Ensure connections are secure before proceeding with measurements.
5. Упатства за работа
5.1 Општа постапка за мерење
- Turn the rotary dial to the desired measurement function.
- Connect the test leads or clamp the jaws to the circuit under test as appropriate for the selected function.
- Read the measurement value(s) on the dual LCD display.
- If the reading is unstable or out of range, adjust the function or range if manual ranging is available.
5.2 Мерење на AC/DC струја (Clamp)
This function measures current without breaking the circuit.
- Свртете го вртливото копче на A~ (AC струја) или A- (DC струја) позиција.
- Отворете го clamp вилиците со притискање на активирачот.
- Вметнете само еден проводник од струјното коло во вилиците. Осигурајте се дека вилиците се целосно затворени.
- Read the current value on the display. For DC current, observe the polarity.
5.3 AC/DC Voltagд Мерење
- Поврзете го црниот тест кабел со COM терминалот и црвениот тест водат до VΩHz терминал.
- Свртете го вртливото копче на V~ (AC Voltagд) или V- (DC Voltagд) позиција.
- Touch the test probes to the desired test points in the circuit.
- Прочитајте го томtagе вредност на екранот.
