Жайгашуу

1. Кубат туташуу: Connect the provided power cord to the oscilloscope and a suitable power outlet (100 to 240VAC, 50/60Hz). The device can also operate on a rechargeable lithium-ion battery (sold separately).
2. Зонд туташуу: Attach the passive voltage probes to the CH1 and CH2 input BNC connectors on the front panel. Ensure a secure connection.
3. Probe Compensation: Before taking measurements, perform probe compensation. Connect the probe tip to the PROBE COMP terminal (typically 5V, 1kHz square wave) and the ground clip to the ground terminal. Adjust the compensation trimmer on the probe until a flat-top square wave is displayed on the screen.
4. Баштапкы күйгүзүү: Press the power button to turn on the oscilloscope. The 8-inch color TFT-LCD will display the startup sequence.
5. PC Software Installation (Optional): If connecting to a PC for data transmission or remote operation, install the provided software from the CD-ROM onto your computer. Connect the oscilloscope to the PC using the USB interface cable.

Иштөө нускамалары

The front panel of the PDS5022T features a clear layout for intuitive operation. Refer to the image above for control locations.

Front Panel Controls Overview

• Дисплей: 8-inch color TFT-LCD with 640 x 480 pixel resolution for waveform viewing.
• Функция баскычтары (F1-F5): Context-sensitive buttons located to the right of the display, used to select options from on-screen menus.
• Vertical Controls (VOLTS/DIV, POSITION): Independent controls for Channel 1 (CH1) and Channel 2 (CH2). The VOLTS/DIV knobs adjust the vertical scale (voltage per division), while the POSITION knobs adjust the vertical position of the waveform.
• Horizontal Controls (SEC/DIV, POSITION): The SEC/DIV knob adjusts the horizontal time base (seconds per division), and the horizontal POSITION knob shifts the waveform left or right.
• Trigger Controls (TRIG LEVEL, TRIG MENU, SET TO 50%, FORCE TRIG, SET TO ZERO): These controls manage how the oscilloscope synchronizes with the input signal. The TRIG LEVEL knob sets the voltagтриггер пайда болгон деңгээл.
• Киргизүү туташтыргычтары: BNC connectors for CH1, CH2, and EXT TRIG (external trigger). The EXT TRIG allows triggering from a third source.
• Utility Buttons:
  • SAVE/RCL: Saves or recalls waveform data and settings. Up to four waveforms can be stored internally.
  • MEASURE: Accesses automatic measurement functions (e.g., period, frequency, peak-to-peak).
  • КУРСОР: Activates and controls screen cursors for manual voltage and time measurements.
  • ACQUIRE: Configures acquisition settings.
  • КӨРСӨТҮҮ: Adjusts display settings.
  • МЕНЮЛАР: Navigates through various menu options.
  • AUTOSET: Automatically adjusts vertical, horizontal, and trigger settings to display a stable waveform.
  • AUTOSCALE: Similar to AUTOSET, selects optimal settings for displaying a waveform. Can be disabled for educational purposes.
  • RUN/STOP: Толкун формасын алууну баштайт же токтотот.
• Math Menu: Provides access to waveform math functions, including addition, subtraction, and FFT (Fast Fourier Transform).

Негизги операция кадамдары

1. Connect Signal: Connect the probe from the desired channel (CH1 or CH2) to the circuit point you wish to measure.
2. Күйгүзүү: Turn on the oscilloscope.
3. Auto-Setup: басыңыз AUTOSET or АВТОМОБИЛЬ button to quickly obtain a stable display of the input signal.
4. Adjust Vertical Scale: колдонуу VOLTS/DIV knob for the active channel to adjust the vertical sensitivity, making the waveform fit the screen appropriately.
5. Adjust Horizontal Scale: колдонуу SEC/DIV knob to adjust the time base, allowing you to view more or less of the waveform horizontally.
6. Adjust Trigger: колдонуу TRIG LEVEL knob to stabilize the waveform. The trigger point is indicated on the screen. For complex waveforms, use the TRIG MENU to access advanced trigger settings like edge, video, and trigger hold-off.
7. Өлчөөлөр: басыңыз ӨЛЧӨ button to display automatic measurements. Use the КУРСОР button to activate and position cursors for manual measurements.
8. Математикалык функциялар: басыңыз MATH MENU button to perform operations like adding or subtracting channels, or performing an FFT analysis.
9. Дайындарды сактоо: колдонуу SAVE/RCL button to save waveform data or instrument settings to internal memory.

Техникалык тейлөө

• Тазалоо: Use a soft, dry cloth to clean the exterior of the oscilloscope. For stubborn dirt, a slightly damp cloth with mild detergent may be used. Avoid abrasive cleaners or solvents.
• Сактагыч: Аппаратты түз күндүн нурунан жана экстремалдык температурадан алыс салкын, кургак чөйрөдө сактаңыз.
• Пробка кам көрүү: Handle probes carefully. Avoid bending or stressing the cables excessively. Keep probe tips clean.
• Батареяга кам көрүү (эгер бар болсо): If using a rechargeable battery, follow the manufacturer's guidelines for charging and storage to maximize battery life.

Проблемаларды чечүү

• Дисплей/кубат жок: Ensure the power cord is securely connected and the power outlet is functional. If using battery, ensure it is charged.
