۳.۱ د بکس خلاصول او محتوا

Upon opening the package, verify that all components are present and undamaged. The standard package includes the Proster ET828 unit, a pair of test probes, a set of 5-color alligator clip test leads, batteries, a storage bag, and this user manual.

4.2 د بیټرۍ نصب کول

The ET828 requires 2 AA batteries for operation. To install the batteries:

1. د وسیلې په شا کې د بیټرۍ د برخې پوښ ومومئ.
2. Open the cover by sliding it or lifting the latch.
3. دوه AA بیټرۍ دننه کړئ، د سم قطبیت ډاډ ترلاسه کړئ (+ او -).
4. د بیټرۍ کمپارټ پوښ په خوندي ډول وتړئ.

۶.۲ د ټیسټ لیډونو نښلول

Connect the test leads to the appropriate input terminals based on the measurement type. The common (COM) terminal is typically used for the black lead, while the red lead connects to the VΩCap, mA mF, or 10A terminal depending on the desired measurement.

5. عملیاتي طریقې

The Proster ET828 offers both multimeter and oscilloscope functionalities, selectable via the central rotary dial.

5.1 Multimeter Functions

Rotate the dial to the desired measurement function. The display will show the current reading and unit.

• والیtage اندازه کول (V): Select DC V or AC V. Connect leads in parallel with the circuit.
• Current Measurement (A/mA/µA): Select DC A or AC A. Connect leads in series with the circuit. Ensure correct terminal usage (10A or mA mF).
• د مقاومت اندازه کول (Ω): Select the Ω range. Connect leads across the component.
• Capacitance Measurement (mF): Select the mF range. Connect leads across the capacitor.
• د فریکونسۍ اندازه کول (Hz): Select the Hz range. Connect leads to the signal source.
• د ډایډ ټیسټ: Select the diode symbol. Connect leads across the diode to measure forward voltage غورځول.
• د دوام ازموینه: Select the continuity symbol. Connect leads across the circuit to check for continuity (a beep indicates continuity).

5.2 Oscilloscope Functions

To enter oscilloscope mode, typically press a dedicated button or rotate the dial to the oscilloscope symbol. The device will display waveforms and related parameters.

• د محرک حالتونه: Select between Auto and Normal trigger modes using the function buttons (F1-F4). Auto mode attempts to trigger on any signal, while Normal mode requires a stable signal to trigger.
• اتوماتیک اندازه کول: The oscilloscope automatically displays parameters such as VPP (Peak-to-Peak Voltage), Vmax (Maximum Voltage), Vmin (Minimum Voltage), Vavg (Average Voltage), Vrms (Root Mean Square Voltage), and Frequency.
• Waveform Capture and Saving: Use the function buttons to capture and save waveforms for later review. The device can save up to 10 waveforms.

6. د معلوماتو مدیریت

The ET828 allows for the retention and storage of measurement data and waveforms.

6.1 Display Retention and Historical Data

The device can display historical measurement data alongside real-time data on the same screen, facilitating comparison and analysis.

6.2 Saving and Recalling Data/Waveforms

The device supports saving up to 100 sets of readings and 10 waveforms. Use the designated function buttons (e.g., 'S' for Save, 'R' for Recall) to manage stored data.

7. ساتنه

7.1 پاکول

Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from all circuits before cleaning.

7.2 د بیټرۍ بدلول

When the low battery indicator appears on the display, replace the batteries as described in Section 4.2. Always use new AA batteries of the same type.

8. ستونزه حل کول

If the device is not functioning as expected, consider the following common issues:

• نه ښودنه: Check battery installation and charge level. Ensure the rotary dial is not in the 'OFF' position.
• ناسم لوستل: Verify test lead connections, selected function, and range. Ensure the probes are making good contact with the circuit.
• Oscilloscope Waveform Issues: Adjust trigger settings (Auto/Normal) and time base/range settings to properly capture the signal.
• وسیله په ناڅاپي ډول بندیږي: The automatic shut-off feature activates after 15 minutes of inactivity. This is normal behavior.
