Hand Calibration
[Note: The CLKTCD12 analog clock hands have been pre-set and aligned at the
factory. This hand location and alignment information is retained in non-volatile
flash.]
[Note: Under normal operating circumstances it should not be necessary to adjust
or align the hands. However, if for any reason, the hands are not tracking the time
code source, an adjustment function has been built into the CLKTCD12]
[Note: The visual determination of the accuracy of the hand display should be done by
comparing the clock hands only after the CLKTCD12 indicates that it is synchronized to
time code, and then only to a digital display or other reference that has also been locked,
preferably to the same time code source. The reference display should be set adjacent to
the CLKTCD12 unit and eye movements should be minimized when doing comparisons.
Please see the troubleshooting section for additional information/suggestions. ]
To adjust the hands:
Select the “ Set “ position for switch S2-8, the unit will enter the adjustment mode; the
hands of the analog clock will stop.
1. Select the “Set” position for switch S2-8 (ON),
2. Select either the 12:00:00 (OFF) or 6:00:00 (ON) position using switch S2-7
3. Depress and release either button B1 [ CW/Forward ] or button B2
[ CCW/Reverse ] button to move the hands in the desired direction for either
12:00:00 o’clock or 6:00:00 o’clock.
[Note: After releasing the button, the hands will rotate in the desired
direction until any button is pressed. This feature allows for easier
setting of the hands]
4. Depress and Hold button B1 or B3 down for 10 seconds to advance rapidly.
Then release. The hands will rotate rapidly until any button is pressed.
[Note: This feature allows for rapid setting of the hands]
5. Stop the hands a few seconds before the desired position.
6. Fine-tune the second hand position to the center of the 12-indicator mark by
pressing the Trim/Forward button B3 to move the second hand in the forward
direction incrementally.
[Note: this function only works in the forward or clockwise direction]
