! The load (light or heavy) on the JOG dial when it is turned can be objectively judged in this mode.
! When the JOG dial is rotated swiftly in this mode, the speed is measured. Either direction, clockwise or
counterclockwise, is OK. The meaning of the numerical value displayed is as follows.
TOP SPEED : Maximum speed given that normal speed is defined as when one rotation takes 1.8.
TIME : Time required for the JOG dial to slow down from 3x speed to 1.5x speed. (msec)
! To measure the time required for slowdown, the maximum speed must be 7 times normal speed or higher.
If the maximum speed does not reach 7.0 times normal speed, the "Please rotate faster." is displayed as a warnig.
! When the measurement is carried out several times in a row, TIME will be displayed as an average of maximum
99 times of the measurement. This evens out the measurement value.
D
! EXAMPLE: The result when measured 5 times.
E
! You can measure up to max 99 times to calculate the average.
[Judgement result]
! Measure it more than 5 times in succession.
! After the fifth and subsequent measurements, if the measured time average (TIME AVR.) is within a certain range, [OK]
will be displayed in the right side of "RESULT". If not, [NG] will be displayed.
