ChronoMaster Auto PRO - Witschi
The ChronoMaster Auto PRO measures the beat noise of mechanical watches. It moves to all main test positions and any intermediate positions automatically and precisely. The movement in two axes is smooth and silent.
The high-quality drive unit was developed to fit the needs of the ChronoMaster Auto PRO. The motors are stowed in the foot section of the device to prevent magnetic fields from affecting the function of the movement. The compact design with a low centre of gravity occupies little space and provides a high degree of stability. The ChronoMaster Auto PRO requires a single USB cable for data connection and power supply for operation with a PC or the Witschi terminal. Alternatively, the measurement data can also be transmitted wirelessly via Bluetooth.
The compact, automatic microphone:
• Acoustic microphone with integrated measuring electronics for the measurement of mechanical movements and watches
• Smooth and silent movement
• Automatic change to the 6 main, 4 intermediate and 2 special test positions
• 360° rotation axis and the 180° tilting axis
• Arbitrary test positions in 1° steps
• Dynamic movement with simultaneous measurement
• Tourbillon measurement
• Precise position control based on gravity thanks to the integrated acceleration sensor
• One single USB cable for power supply and data transmission
• Wireless data transmission via Bluetooth
• Integrated fixation for large and heavy watches
• Convenient operation with the to built-in control buttons
• Ergonomic regulation of movements thanks to stable hand rest for left- and right-handers
• The smart drive unit also allows manual position changes
