Поставување

1. Полнење на уредот

Before initial use, fully charge the device using the provided Type-C USB cable. Connect the cable to the Type-C port on the side of the device and to a 5V 1A power source. The battery indicator on the screen will show charging status. A full charge typically takes approximately 3 hours for the 3000mAh battery.

2. Првично вклучување и избор на јазик

Press and hold the power button on the side of the device to turn it on. Upon first power-on, you will be prompted to select your preferred language. Use the navigation buttons to select 'English' and press 'ENTER'.

3. Connecting Probes

The DST-210 supports various probes for its different functions:

• Multimeter Probes: Insert the red and black multimeter test leads into the corresponding input jacks at the bottom of the device (VΩHz for red, COM for black).
• Oscilloscope Probe: Connect the P6100 oscilloscope probe to the BNC connector labeled 'DSO' on the top of the device. Ensure the probe's attenuation switch is set correctly (e.g., 1X or 10X) to match the device's settings.
• Signal Generator Probe: Connect the alligator clip probe to the 'DDS' BNC connector on the top of the device for signal output.

Работни режими

The DST-210 offers three primary operating modes: Multimeter, Oscilloscope, and Signal Generator. Use the rotary dial to select the desired mode from the main interface.

1. Режим на мултиметар

This mode provides comprehensive digital multimeter functionalities with 19999 counts. It supports auto-ranging for most measurements.

• Мерења: DC/AC Voltage, DC/AC Current, Resistance, Capacitance, Frequency, Diode Test, Continuity Test, Live/Neutral Wire Detection.
• Операција: Rotate the dial to the 'Multimeter' position. The device will automatically attempt to detect the measurement type. Use the navigation buttons to manually select specific measurement types (e.g., AC Voltage vs. DC Voltage) if needed.
• Карактеристики: Curve recording, Max/Min value display, Data hold, Auto power-off.

2. Режим на осцилоскоп

The oscilloscope function allows for waveform visualization and analysis with a 10MHz bandwidth and 48MSa/s sampстапка на линг.

• Мерења: Real-time waveform display, Frequency, Period, Duty Cycle, Vpp, Vmax, Vmin, Vrms, Average.
• Операција: Rotate the dial to the 'Oscilloscope' position. Connect the oscilloscope probe to the circuit under test. Use the navigation buttons to adjust vertical sensitivity (V/div) and horizontal time base (S/div). The 'AUTO' button can automatically optimize display settings.
• Карактеристики: Support trigger level display, infinite persistence, waveform storage and export.

3. DDS Signal Generator Mode

The built-in DDS signal generator can output 13 types of waveforms for various testing and simulation purposes.

• Бранови форми: Sine Wave, Square Wave, Sawtooth Wave, Half-Wave, Full-Wave, Step Wave, Reverse Step Wave, Index Up, Index Decrease, Direct Current, Multi-Audio, Sink Pulse, Lorentz Wave.
• Операција: Rotate the dial to the 'Signal Generator' position. Connect the alligator clip probe to the circuit where the signal is needed. Use the navigation buttons to select the desired waveform type, adjust frequency (0-50KHz), duty cycle (0-100%), and amplitude (0.1V-3.0V).

Одржување

1. Батерија и полнење

The device is powered by a 3000mAh lithium battery. Charge it using the Type-C port (5V 1A). The battery icon on the screen indicates the charge level. For optimal battery life, avoid fully discharging the device frequently.

2. Auto Power-Off

To conserve battery, the device features an auto power-off function. This can be configured in the 'System Settings' menu. Options typically include 15 minutes, 30 minutes, 1 hour, or disabled.

3. Поставки за приказ

The 2.8-inch TFT color screen offers adjustable backlight brightness and theme options (Daylight/Night). These settings can be accessed via the 'System Settings' menu to enhance visibility in different lighting conditions.

4. Firmware Updates and USB Sharing

The device supports firmware updates and USB data sharing. Check the manufacturer's website (www.fnirsi.cn) for the latest firmware and instructions. USB sharing allows for waveform data export to a computer.

Решавање проблеми

• Уредот не се вклучува: Проверете дали батеријата е наполнета. Поврзете ја со полнач од тип C и обидете се повторно.
• No reading in Multimeter mode: Check that the probes are securely connected and that the correct measurement mode is selected for the circuit under test.
• Unstable waveform in Oscilloscope mode: Adjust the trigger level and time base settings. Ensure proper probe connection and attenuation settings.
• Signal Generator not outputting: Verify the probe is connected to the 'DDS' port and that the desired waveform, frequency, and amplitude are configured.
• Screen issues (e.g., flickering, unresponsiveness): Try a factory reset via the 'System Settings' menu. If the issue persists, contact customer support.
