Be sure these instructions accompany the tool
when passed from one user to a new or inex­perienced user.
Rotating equipment can cause flying particles

Wear Safety Goggles (User and bystanders).

Flying particles can cause eye injury.

Keep yourself, clothing and test equipment
clear of moving parts.

PHOTO TACH OPERATION

Contact collar

25’ maximum
distance.

Measurement Procedure:

1. Unscrew contact collar from optical end of
505L (if attached).

2. Attach a piece of reflectIive tape on the rotating object to
be measured.

3. Depress and hold the START button and then press the
Photo button (lower right) on the 505L.

4. With the start button depressed, point the optical end at
the rotating surface so the relective tape passes the
laser every rotation.

Note: The 505L can be set to continuous on, eliminating

the need to hold the START button down. Press and hold
the START button then press the MEMORY button. “L-on”

will display indicating continuous on is activated. Deactivate
continuous on by holding down the START button and press the
MEMORY button. “L-off” will display indicating continuous on is
deactivated.

5. Read the RPM on the LCD display.

Maximum distance to target is dependent on several items like
the strengh of reflection of the laser, ambient light conditions,
and the surface of the item under test. For best results the
background surface should be dark as compared to the reflec­tive tape. If readings are unstable, move closer to the target for
better performance. At long distances a tripod or other rest
may be necessary for proper function.

on the 505L.

4. While pressing the START button, hold the
wheel against the center end of the rotat­ing shaft.
Note: The 505L can be set to contin­uous on, eliminating the need to hold
the START button down. Press and hold the START
button then press the MEMORY button. “L-on” will dis-

play indicating continuous on is activated. Deactivate con­tinuous on by holding down the START button and press the
MEMORY button. “L-off” will display indicating continuous
on is deactivated.

5. Read the RPM on the LCD.

Lightly press the cone or concave tip to the center of
the rotating shaft. Measuring from anywhere but the
center will result in incorrect readings.
