Operation

Readout and Operation: Unit shall register a total count of 15 turns.

The number in the window (0 thru 14) indicates completed number of

turns of the drive sleeve. Graduated circular dial indicates the percent

of a partial turn of the drive sleeve.

Minor Scale Division: 1/50 turn

Indication: 0 to 14.99 turn

Brake Lever: 1st position (15° movement of brake lever) operates a

high torque system for fine adjustment; 2nd position (15° additional

movement of brake lever) actuates brake.

Accuracy: Backlash shall be zero between graduated dial and drive

sleeve

Rotation: The indication shall increase with clockwise and decrease

with a counterclockwise rotation.

Transfer Point: The number in the center of the window shall

change as graduated dial rotates between 94 and 0.

Mechanical

Shaft Bore: 0.250”

Runout: 0.004 in/in (Note 1)

Mounting: Install mounting bracket (included) between panel and

panel nut. Multidial shall mount directly to shaft with No. 2-56 spline

socket set screw, located adjacent to No. 50 on graduated dial (hex key

included).

Note 1. Dial to be free running and without binds when axis of drive
