[2] Quality judging of JOG dial load.
When it spends a power supply while pushing a FUNCTION button and a ACTIVE button of left deck simultaneously,
enters into this mode. (Please continue pushing until an opening display is completed. )
It is the mode which judges the load (light/heavy) when rotating JOG dial .
It goes into this mode, when JOG dial was turned with sufficient vigor, the following top speed and rotation fall time are
measured and top speed becomes more than 7 times, rotation fall time is evaluated, and it judges whether it goes into the
range of regular, and a result is displayed on LED.
The rotation direction, right rotation and left rotation, either is OK.
TOP SPEED : Top speed (let the time of turning one rotation in 1.8 second be 1 time speed)
ROTATION FALL TIME : Time taken for rotation to fall to 1.5 times speed from 3 times speed
It is necessary to make it rotate top speed to 7.0 or more times to measure the rotation fall time required.
Not more than 7.0 times faster, it is made to blink 3 times and warns of JOG illuminations.
4 times displays the number of times of measurement on L ED.
The 1st end HOT CUE 1 ( SIZE <- ) lighting
The 2nd end HOT CUE 2 ( SIZE -> ) lighting
The 3rd end HOT CUE 3 ( BWD <- ) lighting
The 4th end HOT CUE 4 ( FWD -> ) lighting
After measurement finishes 4 times, an average is taken, and rotation fall time judges whether it goes into the range of regular,
and displays a result on LED.
Regulation value is 100 ± 40 [msec].
OK LOOP ACTIVE lighting
NG (Light) LOOP OUT lighting
NG (Heavy) LOOP IN lighting
Measurement is performed although the number of times is not displayed 5th henceforth.
Each time, an average is taken and a result is displayed on LED.
