Product overview
YD-10 combines a precision digital motor with control and measurement functions for checking speed instruments, speed sensors and measurement systems, including zero-speed, reverse-rotation and overspeed-protection applications. The catalog presents it for field calibration and laboratory speed calibration.
Drive and control components are integrated in a portable aluminum-alloy case. The catalog describes smooth rotation, low vibration and low noise, automatic calibration from the keypad, and Windows software for operation, data recording and report printing.

Range and accuracy limitations
The catalog does not give an accuracy value for internal measurement at 100–10000 r/min. The output accuracy of 0 r/min and rotor-speed unit r/min/S require confirmation. The relationship between the 1–500 r/min speed range and the other listed ranges is not established. These entries do not justify a zero-error claim or an expanded mechanical rotation range.
