Setup

1. Power Connection: Connect the provided power adapter to the oscilloscope's power input and then to a suitable AC power outlet.
2. Probe Connection: Connect the BNC end of the oscilloscope probes to the CH1 and CH2 input connectors on the front panel. Ensure the connection is secure.
3. Probe Compensation: Before taking measurements, it is recommended to compensate the probes. Connect the probe tip to the probe compensation signal output (usually a square wave test point on the front panel) and the ground clip to the ground terminal. Adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen. Use a non-metallic adjustment tool.

Operating Instructions

Powering On/Off

Press the power button located on the front panel to turn the oscilloscope on or off.

Basic Waveform Display

After powering on, connect a signal to one of the input channels (e.g., CH1).

Press the AutoSet button to automatically adjust the vertical and horizontal settings for a stable waveform display.

Channel Control

Use the CH1 and CH2 buttons to enable or disable respective channels.

Adjust the vertical scale (Volts/div) using the Vertical Scale knob for each channel.

Adjust the vertical position using the Vertical Position knob for each channel.

Horizontal Control

Adjust the horizontal scale (Time/div) using the Horizontal Scale knob.

Adjust the horizontal position using the Horizontal Position knob.

Trigger System

The trigger system stabilizes repetitive waveforms and captures single-shot events.

Use the Trigger Level knob to set the trigger voltage level.

Press the Trigger Menu button to access trigger settings such as edge type (rising/falling), source, and mode.

Measurements

The oscilloscope supports 30 automatic measurement functions.

Press the Measure button to display a menu of available measurements (e.g., Vpp, Vmax, Vmin, Frequency, Period). Select desired measurements to display them on screen.

The built-in 6-digit hardware frequency counter can measure frequencies from 2 Hz to 20 MHz.

Data Storage and Connectivity

The device features a USB host interface for connecting a USB flash drive to save waveform data or screenshots.

It also has a USB device interface for connecting to a computer for remote control and data transfer.

The memory depth of 10,000 sampling points allows for detailed waveform recording.

Maintenance

Cleaning: Use a soft, dry cloth to clean the exterior of the oscilloscope. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the device. Do not use abrasive cleaners or solvents.

Probe Care: Keep probes clean and free from dust. Store them properly to prevent damage to the tips and cables.

Storage: When not in use for extended periods, store the oscilloscope in a cool, dry place, away from direct sunlight and extreme temperatures.

Troubleshooting

No Display After Power On

• Ensure the power adapter is securely connected to both the oscilloscope and the power outlet.
• Verify the power outlet is functional.

Unstable Waveform

• Adjust the trigger level.
• Check the trigger source and mode settings.
• Ensure the probe is properly compensated.
• Verify the signal input is within the oscilloscope's measurement range.

No Signal Displayed

• Check if the input channel is enabled.
• Ensure the probe is correctly connected to the signal source and the oscilloscope.
• Verify the probe's attenuation setting (x1/x10) matches the oscilloscope's setting.
• Adjust the vertical scale (Volts/div) to an appropriate range.

USB Storage Not Recognized

• Ensure the USB flash drive is formatted correctly (FAT32 is usually recommended).
• Try a different USB port or a different USB flash drive.
