5. Operation
5.1. Power On/Off
Long press the Power button (⑂) to turn the tuner ON. Long press it again to turn it OFF.
5.2. Selecting Tuning Mode (Vibration/Sound)
Short press the MIC/CLIP button to toggle between:
- CLIP (Vibration) Mode: The tuner detects pitch through vibrations when clipped directly onto the instrument. This mode is recommended for noisy environments.
- MIC (Sound) Mode: The tuner detects pitch through its built-in microphone. This mode is suitable for quiet environments.
5.3. Selecting Tuning Method (Automatic/Manual)
Short press the Manual/Auto button to toggle between:
- Auto (Automatic) Mode: The tuner automatically identifies the note being played.
- Manual Mode: Allows you to manually select the target note/key using the Up/Down buttons.
5.4. Key Selection (Manual Mode)
In Manual mode, use the Up (▲) and Down (▼) buttons to cycle through different keys (e.g., C, D, E, F, G, A, B) to match your Guzheng's tuning requirements.
5.5. A4 Frequency Adjustment
The standard A4 reference frequency is 440Hz. If needed, you can adjust this value using the Up (▲) and Down (▼) buttons when the A4 frequency is displayed.
5.6. Tuning Your Guzheng
- Attach/Position: For CLIP mode, attach the tuner securely to a part of your Guzheng that vibrates well (e.g., near the tuning pegs). For MIC mode, place the tuner close to the instrument in a quiet area.
- Pluck a String: Pluck a single string on your Guzheng.
- Observe the Display:
- If the needle/bar on the display is in the center and the light is green, the string is in tune.
- If the needle/bar is to the left of center and the light is red, the string is flat. You need to tighten the string.
- If the needle/bar is to the right of center and the light is red, the string is sharp. You need to loosen the string.
- Adjust with Wrench: Use the integrated tuning spanner to carefully adjust the corresponding tuning peg. Turn clockwise to tighten (sharpen) and counter-clockwise to loosen (flatten).
- Repeat: Continue plucking and adjusting until the display shows the string is in tune. Repeat for all strings.

9. User Tips
- For the most accurate tuning, especially in environments with background noise, always use the CLIP (Vibration) mode by attaching the tuner directly to the Guzheng.
- Before starting your tuning session, quickly verify that the A4 reference frequency is set to your desired standard (commonly 440Hz).
- When replacing strings or performing a major re-tuning, it's helpful to roughly tune the strings by ear first, then use the WST-600B for fine-tuning precision.
