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.

Слика 3.1: Предња страна 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.

Кључне компоненте:

• ЛЦД екран: Shows waveform, measurement readings, and settings.
• Функцијска дугмад (F1-F4): Context-sensitive buttons for menu navigation and settings adjustment.
• Дугме АУТО: Аутоматски подешава подешавања осцилоскопа за оптималан приказ таласног облика.
• Дугме САВЕ: Saves current waveform or measurement data.
• Ротари Диал: Selects between Oscilloscope (OSC) and various Multimeter functions (V~, V-, Ω, Cx, 10A, etc.).
• Улазни прикључци:
  • 10А: Input for high current measurements.
  • ЦОМ: Common (ground) input for all measurements.
  • VΩCx: Улаз за волtage, resistance, capacitance, diode, and continuity measurements, and oscilloscope input.

4. Подешавање

4.1. Укључивање/искључивање

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. Прикључак сонде

За већину мерења (запреминаtage, resistance, capacitance, oscilloscope), connect the black probe to the ЦОМ 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 ЦОМ Јацк.

5. Радни режими

5.1. Oscilloscope Mode (OSC)

Окрените окретни точкић на ОСЦ position to enter oscilloscope mode. The screen will display a waveform graph.

• Дугме АУТО: Притисните АУТО for automatic waveform scaling and positioning. This is useful for quickly getting a stable display.
• Дугмад F1-F4: 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.
• Waveform Parameters: The display typically shows key parameters like Peak-to-Peak Voltage (Vp-p), Average Voltage (Vavg), RMS Voltage (Vrms), and Frequency (kHz).
• Дугме САВЕ: Користите САВЕ button to store the current waveform data for later review.

5.2. Режим мултиметра

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.

• ВолtagМерење (V~ / V-): Connect probes in parallel with the circuit component. Select AC (V~) or DC (V-) as appropriate.
• Мерење отпора (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): УПОЗОРЕЊЕ: 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. Одржавање

• Чишћење: Користите меку, дamp крпу за чишћење уређаја. Не користите абразивна средства за чишћење или раствараче.
• Одржавање батерије: Recharge the internal battery regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
• Складиштење: Уређај чувајте на хладном и сувом месту, даље од директне сунчеве светлости и екстремних температура.
• Probe Inspection: Periodically check probes and leads for cuts, cracks, or frayed insulation. Replace damaged leads immediately to prevent electrical hazards.
