3. המוצר נגמרview

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.

איור 3.1: חזית 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.

מרכיבי מפתח:

• תצוגת LCD: Shows waveform, measurement readings, and settings.
• כפתורי פונקציה (F1-F4): Context-sensitive buttons for menu navigation and settings adjustment.
• לחצן AUTO: Automatically adjusts oscilloscope settings for optimal waveform display.
• לחצן שמירה: Saves current waveform or measurement data.
• חוגה סיבובית: Selects between Oscilloscope (OSC) and various Multimeter functions (V~, V-, Ω, Cx, 10A, etc.).
• שקעי קלט:
  • 10A: קלט למדידות זרם גבוה.
  • COM: Common (ground) input for all measurements.
  • VΩCx: קלט עבור כרךtage, resistance, capacitance, diode, and continuity measurements, and oscilloscope input.

4. התקנה

4.1. הפעלה / כיבוי

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. חיבור גשש

עבור רוב המדידות (נפחtage, 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 10A jack and the black probe to the COM ג'ֵק.

5. מצבי הפעלה

5.1. Oscilloscope Mode (OSC)

סובב את החוגה הסיבובית למצב OSC position to enter oscilloscope mode. The screen will display a waveform graph.

• לחצן AUTO: לִלְחוֹץ AUTO for automatic waveform scaling and positioning. This is useful for quickly getting a stable display.
• כפתורי 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.
• פרמטרים של צורת גל: The display typically shows key parameters like Peak-to-Peak Voltage (Vp-p), Average Voltage (Vavg), RMS Voltage (Vrms), and Frequency (kHz).
• לחצן שמירה: השתמש ב- לְהַצִיל button to store the current waveform data for later review.

5.2. מצב רב-מודד

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

• כרך ידtagמדידה (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): אַזהָרָה: 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.
• בדיקת דיודה / רציפות: These functions are typically grouped. Diode test measures forward voltage drop. Continuity test emits a beep for low resistance connections.

6. תחזוקה

• ניקוי: השתמש רך, דamp מטלית לניקוי המכשיר. אין להשתמש בחומרי ניקוי שוחקים או ממסים.
• טיפול בסוללה: Recharge the internal battery regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
• אִחסוּן: יש לאחסן את המכשיר במקום קריר ויבש, הרחק מאור שמש ישיר וטמפרטורות קיצוניות.
• בדיקת בדיקה: Periodically check probes and leads for cuts, cracks, or frayed insulation. Replace damaged leads immediately to prevent electrical hazards.
