3.Rotational speed drift range: 3000RPM ± 1RPM (@Actual testing of motor rotation speed after 8 hours of operation)

4. RPM meter: High sampling digital rotational speed meter (Sampling display update rate within 0.3 seconds) 

5. For 4 stages of dial-setting speed and manual stage selection speed output (MANUAL MODE) and one set of single stage VR stepless sweep speed which controls output (SWEEP MODE)

6.DUTY test function: output signal from the unit connector group to the external DUTY display, showing DUTY values.

7.With external input control function: by the external control signal control machine speed jump segment control and stop function

8. With SWEEP upwave/continuous/speed drop sweep function: set the speed-up sweep/continuous speed/speed via the thumb switch
