• 7-Stroke Adjustment System – Rotate the metal ring to precisely adjust stroke length from 2.3mm to 4.5mm across 7 positions (2.3/2.7/3.0/3.4/3.8/4.2/4.5mm). This allows you to switch seamlessly between line work and soft shading techniques, adapting to your preferred style.
• Voltage Control & Working Timer – Press ± to fine‑tune voltage in 0.1V steps (4‑12V range), or long‑press for rapid adjustment. Long‑press the power button 3 seconds to turn on/off. Double‑click the power button to reset the timer (which counts up in 1‑minute increments), helping you track your session duration accurately.
• Three Memory Voltage Modes – Single‑click the M button to cycle through three saved voltage presets (M1/M2/M3), storing your favorite settings for different tasks. Double‑click M to enable/disable the strong‑start mode (lightning icon on screen), giving you an instant power boost at the beginning of each stroke.
• High‑Clarity TFT Display – The low‑brightness, soft‑light screen clearly shows battery level, dot mode status, current voltage, working timer, and other key data. The gentle backlight ensures comfortable viewing even during long sessions without eye strain.
• Programmable Dot Frequency – Long‑press the M button to enter dot mode. Use the ± buttons to adjust the interval from 01 to 45 (00 = normal continuous mode with no dot effect; 01 = slow dot rhythm; 45 = fast dot rhythm). This lets you customize the stippling rhythm to match your preferred shading and texture style.
