4.4 Indstillingsproces

Once the tuner is attached and powered on, pluck a single string on your instrument. The display will show the note name and indicate whether the note is sharp, flat, or in tune.

• If the note is flat, the indicator will show below the center, and the display might be blue or red depending on the mode. Tighten the string.
• If the note is sharp, the indicator will show above the center, and the display might be blue or red depending on the mode. Loosen the string.
• When the note is in tune, the indicator will be centered, and the display will typically turn green or show a stable pattern.

4.5 Compensated Tuning

The WST-905Li features a compensated tuning method, particularly useful for guitars, to achieve a more harmonized sound across the fretboard. This mode adjusts the target pitch slightly for each string to account for intonation imperfections inherent in stringed instruments.

To use compensated tuning, select the appropriate mode (e.g., Guitar mode) and follow the on-screen instructions or refer to the specific compensation values provided in the manual or on the product's support page. This feature allows for a more precise and musically pleasing tuning experience.
