5. Setup

5.1 Initial Charging

Before first use, fully charge the device using the provided Type-C USB cable. Connect the cable to the Type-C port on the device and a standard 5V/A USB power source. The built-in 400mAh lithium battery provides up to 12 hours of continuous work on a full charge.

5.2 Power On/Off

• To power on: Press and hold the power button until the screen illuminates.
• To power off: Press and hold the power button until the screen turns off. The device also supports automatic shutdown, configurable from 5 minutes to 120 minutes.

5.3 Language Selection

The device supports Chinese and English. Refer to the on-screen menu or the included manual for instructions on how to switch languages.

5.4 Screen Orientation and Backlight

The 1.14'' color screen can be flipped left or right to adapt to different measurement scenarios. Backlight brightness is adjustable from 10% to 100% for optimal visibility. Consult the device's menu for these settings.

5.5 Replacing Tweezer Tips

The device comes with replaceable brass-plated tweezer tips. To replace them, carefully unscrew the retaining screws, remove the old tips, and insert the new ones, ensuring they are securely fastened. An extra pair of straight tips is included.

6. Operating Instructions

6.1 Automatic Measurement

The SK-BD1 features intelligent recognition and automatic measurement. Simply power on the device and touch the component with the tweezer tips. The device will automatically identify the component type (Resistor, Capacitor, Inductor, Diode, or Continuity) and display its primary and secondary parameters.

6.2 Manual Mode Selection (Gear Level)

While the device offers an auto-ranging mode, you can also manually select the measurement mode (Resistor, Capacitor, Inductor, Diode, On-Off) for specific testing requirements. Refer to the device's menu for mode selection.

6.3 Understanding the Display

The 1.14'' color screen displays up to 9999 characters for the main parameter measurement area (L/C/R tests) and up to 4 decimal places for secondary parameters (D/Q tests). The D-value (Dissipation Factor) for capacitors and Q-value (Quality Factor) for inductors provide insight into component quality, which is a key advantage over standard multimeters.

6.4 Data Hold

Press the "HOLD" button to freeze the current measurement on the screen. Press it again to release the hold function and resume live measurements.

6.5 Frequency and Level Testing

The device allows selection of test frequencies (100Hz, 1kHz, 10KHz) and test levels (0.3Vrms, 0.6Vrms) to suit different component characteristics and testing standards. These settings can typically be adjusted via the device's menu.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Avoid using abrasive cleaners or solvents.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently and store the device with a partial charge if not used for extended periods.
• Tweezer Tip Replacement: Regularly inspect the tweezer tips for wear or damage. Replace them as needed using the instructions in Section 5.5.
• Firmware Upgrade: The device supports firmware upgrades. Refer to the manufacturer's website or support documentation for instructions on how to perform an upgrade.
• Calibration: The device supports calibration settings (0Ω-10MΩ, OPEN). If you suspect measurement inaccuracies, consult the manual for calibration procedures.
• Restore Factory Settings: An option to restore factory settings is available in the device's menu. Use this with caution as it will erase custom settings.

8. Troubleshooting

• Device not powering on: Ensure the battery is charged. Connect the device to a Type-C charger and try again.
• Inaccurate readings:
  • Check if the tweezer tips are clean and making good contact with the component.
  • Ensure the correct measurement mode (Auto or manual L/C/R) is selected.
  • Consider performing a calibration if persistent inaccuracies occur (refer to Section 7).
• Screen display issues: Adjust backlight brightness (Section 5.4). If the screen is unresponsive, try restarting the device.
• Component not recognized: Ensure the component is properly isolated and the tweezer tips are making firm contact.

9. User Tips

• Branding Variation: Some users have noted that their device displays "ZOYI" upon startup, despite being branded as SNAKOL. This appears to be a common occurrence and does not affect the functionality or specifications of the device.
• SMD Component Testing: The tweezer design is particularly effective for testing Surface Mount Devices (SMD) directly on a PCB or when handling small components, facilitating quick batch screening.
• D/Q Value Importance: Pay attention to the D (Dissipation Factor) and Q (Quality Factor) values, especially for capacitors and inductors. These values provide critical information about the component's quality and health beyond just its primary value, helping to identify faulty parts that might otherwise seem fine with a basic multimeter.

10. Warranty and Support

For warranty information, technical support, or service inquiries, please refer to the contact details provided in the original product packaging or contact the seller directly. Keep your purchase receipt as proof of purchase.
