3. Прадукт скончыўсяview

The TOOLTOP ET2010A integrates a digital oscilloscope and a multimeter into a compact, handheld unit. Below is an illustration of the device with its main components identified.

Малюнак 3.1: Спераду view of the TOOLTOP ET2010A. This image shows the device from a front-right angle. The screen displays an oscilloscope waveform. Probes are connected to the 10A and VΩCx input jacks. The rotary dial is set to an oscilloscope function.

Ключавыя кампаненты:

• ВК-дысплей: Shows waveform, measurement readings, and settings.
• Функцыянальныя кнопкі (F1-F4): Context-sensitive buttons for menu navigation and settings adjustment.
• Кнопка AUTO: Аўтаматычна наладжвае параметры асцылографа для аптымальнага адлюстравання формы сігналу.
• Кнопка ЗАХАВАЦЬ: Saves current waveform or measurement data.
• Паваротны цыферблат: Selects between Oscilloscope (OSC) and various Multimeter functions (V~, V-, Ω, Cx, 10A, etc.).
• Уваходныя гнязда:
  • 10А: Input for high current measurements.
  • COM: Агульны (зазямляльны) уваход для ўсіх вымярэнняў.
  • VΩCx: Уваход для тtage, resistance, capacitance, diode, and continuity measurements, and oscilloscope input.

4. Настройка

4.1. Уключэнне / выключэнне харчавання

The device is powered by an internal rechargeable battery. To power on, press and hold the power button (usually integrated with one of the function buttons or a dedicated button, not explicitly visible in the provided image, assume standard operation). To power off, press and hold the same button. Ensure the device is charged before first use.

4.2. Падключэнне зонда

Для большасці вымярэнняў (аб'ёмtage, resistance, capacitance, oscilloscope), connect the black probe to the COM jack and the red probe to the VΩCx jack. For high current (10A) measurements, connect the red probe to the 10А jack and the black probe to the COM дамкрат.

5. Рэжымы працы

5.1. Oscilloscope Mode (OSC)

Павярніце паваротны дыск у OSC position to enter oscilloscope mode. The screen will display a waveform graph.

• Кнопка AUTO: Прэса АЎТА for automatic waveform scaling and positioning. This is useful for quickly getting a stable display.
• F1-F4 Buttons: These buttons control various oscilloscope parameters such as vertical sensitivity (Volts/Div), horizontal time base (Time/Div), trigger settings, and measurement cursors. Refer to the on-screen menu for specific functions.
• Параметры формы сігналу: The display typically shows key parameters like Peak-to-Peak Voltage (Vp-p), Average Voltage (Vavg), RMS Voltage (Vrms), and Frequency (kHz).
• Кнопка ЗАХАВАЦЬ: Выкарыстоўвайце ЗАХАВАЦЬ button to store the current waveform data for later review.

5.2. Multimeter Mode

Turn the rotary dial to the desired measurement function (e.g., V~ for AC voltage, V- for DC voltage, Ω for resistance, Cx for capacitance, 10A for current). Ensure probes are connected to the correct jacks for the selected measurement.

• тtage Measurement (V~ / V-): Connect probes in parallel with the circuit component. Select AC (V~) or DC (V-) as appropriate.
• Resistance Measurement (Ω): Ensure the circuit is de-energized. Connect probes across the component.
• Capacitance Measurement (Cx): Ensure the capacitor is discharged before connecting probes.
• Current Measurement (10A): ПАПЯРЭДЖАННЕ: Connect the meter in series with the circuit. Ensure the red probe is in the 10A jack. Never connect the meter in parallel when measuring current, as this can damage the device and the circuit.
• Diode Test / Continuity: These functions are typically grouped. Diode test measures forward voltage drop. Continuity test emits a beep for low resistance connections.

6. Тэхнічнае абслугоўванне

• Уборка: Выкарыстоўвайце мяккі, damp тканінай для чысткі прылады. Не выкарыстоўвайце абразіўныя ачышчальнікі або растваральнікі.
• Сыход за батарэяй: Recharge the internal battery regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
• захоўванне: Захоўвайце прыладу ў прахалодным, сухім месцы, удалечыні ад прамых сонечных прамянёў і экстрэмальных тэмператур.
• Праверка зонда: Periodically check probes and leads for cuts, cracks, or frayed insulation. Replace damaged leads immediately to prevent electrical hazards.
