3. Produktet er slutview
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.

Figur 3.1: Forside 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.
Nøglekomponenter:
- LCD-skærm: Shows waveform, measurement readings, and settings.
- Funktionsknapper (F1-F4): Context-sensitive buttons for menu navigation and settings adjustment.
- AUTO knap: Automatically adjusts oscilloscope settings for optimal waveform display.
- GEM knap: Saves current waveform or measurement data.
- Drejeskive: Selects between Oscilloscope (OSC) and various Multimeter functions (V~, V-, Ω, Cx, 10A, etc.).
- Indgangsstik:
- 10A: Input for high current measurements.
- COM: Fælles (jord) indgang for alle målinger.
- VΩCx: Input til bdtage, resistance, capacitance, diode, and continuity measurements, and oscilloscope input.
4. Opsætning
4.1. Tænd/sluk
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. Tilslutning af sonde
For de fleste målinger (volumentage, resistance, capacitance, oscilloscope), connect the black probe to the KOM jack and the red probe to the VΩCx jack. For high current (10A) measurements, connect the red probe to the 10A jack and the black probe to the KOM stik.
5. Driftstilstande
5.1. Oscilloscope Mode (OSC)
Drej drejeknappen til OSC position to enter oscilloscope mode. The screen will display a waveform graph.
- AUTO knap: Trykke AUTO 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.
- Waveform Parameters: The display typically shows key parameters like Peak-to-Peak Voltage (Vp-p), Average Voltage (Vavg), RMS Voltage (Vrms), and Frequency (kHz).
- GEM knap: Brug SPARE button to store the current waveform data for later review.
5.2. Multimetertilstand
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.
- Voltage Måling (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): ADVARSEL: 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. Vedligeholdelse
- Rensning: Brug en blød, damp klud til at rengøre enheden. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Batteripleje: Recharge the internal battery regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Opbevaring: Opbevar enheden et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.
- Sondeinspektion: Periodically check probes and leads for cuts, cracks, or frayed insulation. Replace damaged leads immediately to prevent electrical hazards.
7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Enheden tænder ikke. | Lavt eller afladet batteri. | Oplad enheden ved hjælp af den medfølgende oplader. |
| No waveform displayed in OSC mode. | Incorrect probe connection, signal too small/large, or incorrect time/voltage indstillinger. | Ensure probes are connected to VΩCx and COM. Press the AUTO button. Adjust Volts/Div and Time/Div settings manually. |
