1. Product Introduction

The FNIRSI DSO510 is a highly practical and cost-effective handheld oscilloscope designed for the maintenance and development education industries. This oscilloscope features a real-time sampling rate of 48MS/s, 10MHz bandwidth, and complete triggering functions (single, normal, auto). It can be used for both periodic analog signals and non-periodic digital signals, and can measure up to ±400V voltage. It includes an efficient one-click AUTO function, which displays the measured waveform without complicated adjustments. Additionally, it comes with a multi-function signal generator (50KHz). The device is equipped with a 2.8-inch 320x240 resolution HD LCD screen and a built-in 1000mAh high-quality lithium battery, providing approximately 4 hours of use when fully charged.

5. Screen Indication

5.1 Oscilloscope Interface

The oscilloscope interface displays the waveform and various parameters. Key indicators include:

1. Vertical unit: Represents the voltage per large grid in the vertical direction.
2. Trigger mode indicator icon: "Auto" for automatic triggering, "Single" for single triggering, "Normal" for normal triggering.
3. Probe ratio: Must be consistent with the 1X/10X switch on the probe handle. 1X measures 40V, 10X measures 400V.
4. Input coupling method indicator icon: "AC" for AC coupling, "DC" for DC coupling.
5. Trigger voltage indicator icon.
6. Trigger position indicator icon.
7. Baseline indicator icon: Indicates the current position as 0V voltage.
8. Horizontal time base: Represents the length of time per large grid in the horizontal direction.
9. Run/pause indicator icon: "RUN" indicates running, "STOP" indicates pause.
10. Trigger edge indicator icon.
11. V H (Vertical/Horizontal): Left/right controls the time base; up/down controls the vertical sensitivity of the channel.
12. Battery level: Indicates the remaining battery charge.

Additionally, the interface shows:

• Frequency (Freq): e.g., 200.00Hz
• Duty Cycle (Duty+): e.g., 43.96%
• Peak-to-peak voltage (Vp-p): e.g., 1.20mV

5.2 Oscilloscope Parameter Settings Interface

Accessed by long pressing the MODE button from the main oscilloscope interface. This interface allows detailed configuration:

1. Waveform: Set coupling type, probe ratio, trigger mode, and trigger edge.
2. Parameter: Toggle parameter display for frequency, period, positive duty cycle, negative duty cycle, positive pulse width, negative pulse width, maximum value, minimum value, peak-to-peak value, amplitude, RMS value, and average value.
3. Persistence: Set afterglow options: off, 500ms, 1s, or ∞ (infinite).
4. Image: View saved images.

5.3 Signal Generator Interface

This interface allows configuration and control of the built-in signal generator:

1. Waveforms selection: Choose from Sine Wave, Square Wave, Sawtooth Wave, Half-wave, Full Wave, Step Wave.
2. Display of waveforms: Visual representation of the selected waveform.
3. Frequency setting: Adjust the output frequency (e.g., 01 000 Hz).
4. Duty cycle setting: Adjust the duty cycle (e.g., 050 %).
5. Amplitude setting: Adjust the output amplitude (e.g., 3.0 V).
6. Opening and closing of signal generator: Indicated by graying out when closed.
7. Battery level: Indicates the remaining battery charge.

5.4 Settings Interface

The settings interface allows customization of various device options:

1. Set single item selection:

Options include Language, Sound and light, Startup on boot, Theme, Auto Shutdown, USB Sharing, About, and Factory Reset.

2. Specific settings details:

1. Language: Choose between Chinese and English.
2. Sound and light: Adjust Brightness (25-100) and Sound (0-10).
3. Startup on Boot: Configure the device to automatically start in "turn off", "oscilloscope", or "signal generator" mode upon startup.
4. Theme: Select between blue and yellow themes.
5. Auto shutdown: Set automatic shutdown time to off, 15 minutes, 30 minutes, or 1 hour.
6. USB Sharing: Enable this to connect the device to a computer via USB interface for transferring pictures.
7. About: View brand information and version number.
8. Factory Reset: Resets all settings to their default values. A caution message "Factory Reset will undo all previous changes!" is displayed before proceeding.

6. Firmware Update

To update the firmware:

1. While the device is shut down, press and hold the power button (⏻).
2. Use a Type-C cable to connect the device's Type-C port to a computer. A USB drive named "IAP" will appear on the computer.
3. Drag the firmware file into the "IAP" USB drive. Once the firmware upgrade is complete, the device will automatically jump to the APP.

7. Points for Attention

• After receiving the device, ensure it is fully charged before use.
• When using the oscilloscope, pay attention to the selection of the gear, and ensure the oscilloscope's gear setting is consistent with the probe's gear.
• When measuring high voltage, do not touch any metal parts of the oscilloscope to avoid the risk of electric shock.
• Avoid conducting high-voltage tests while the device is charging.
• When calibrating, unplug the BNC probe or short circuit the positive and negative terminals of the probe.
• USB firmware upgrade only supports WIN10 and above. Do not drag files other than the released firmware, as this may cause irreparable consequences.
• Charge the device using the voltage specified in this instruction manual.
