Sweep mode 

Sweep mode is the default mode and displays a continuous second-hand smooth motion. 
 

Step mode 

The step mode motion is similar to the motion of a quartz clock. The hand will pulse in one-second 
intervals. 
 

To adjust the hands 

1.

 

Click [Clock Hand Position] to enter the alignment window. 

2.

 

Select the box, “Check to set clock”. 

3.

 

Enter the correct hour, minute and second currently displayed on the face of the clock.  
If the second is not currently aligned on a second mark, you can nudge the second hand 
forward incrementally by clicking [Forward]. 

4.

 

Click [OK] to accept the new settings. 

 
The new hand alignment settings will be stored in non-volatile flash. The clock hands will adjust to the 
new settings and display the time after several moments.   
 

 

You can check the new settings with a digital display reference at this point to ensure 
that the hands have been correctly set.
