WARNING
Read instructions before operating:
Be sure these instructions accompany the tool
when passed from one user to a new or inex-
perienced 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.
Note: To zero previous readings on all tach
operations, Press and hold the START
button then press the desired function
button. If a stored value appears,
release START button until the display
goes off. Then press the START button
immediately and a zero reading will be
displayed until the unit is used for mea-
suring RPM or the START button is
released.

PHOTO TACH OPERATION
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 STARTbutton 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 STARTbutton down. Press and hold
the STARTbutton then press the MEMORYbutton. “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 reflec-
tive 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.

CONTACT TACH OPERATION
Measurement Procedure:
1. Screw the contact collar onto the optical
end of the 505L.
2. Attach the cone or concave tip to end of
the contact collar shaft.
3. Press and hold the STARTbutton and
then press the Contact button (lower left)
on the 505L.
4. While pressing the STARTbutton, hold the
wheel against the center end of the rotat-
ing shaft.
Note: The 505L can be set to contin-
uous on, eliminating the need to hold
the STARTbutton down. Press and hold the START
button then press the MEMORYbutton. “L-on” will dis-
play indicating continuous on is activated. Deactivate con-
tinuous 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.

SURFACE SPEED OPERATION
Measurement Procedure:
1. Screw the contact collar onto the optical
end of the 505L.
2. Attach the surface speed wheel to the
end of the contact collar shaft.
3. Press and hold the STARTbutton and then
press the ft/min (feet per minute) or m/min
(meters per minute) on the 505L.
4. While pressing the STARTbutton, hold the
wheel against the moving surface.
Note: The 505L can be set to continu-
ous on, eliminating the need to hold the
STARTbutton down. Press and hold the STARTbut-
ton then press the MEMORYbutton. “L-on” will display
indicating continuous on is activated. Deactivate continuous
on by holding down the START button and press the MEMO-
RY button. “L-off” will display indicating continuous on is
deactivated.
5. Read the speed on the LCD.
Note: In this mode the meter displays the surface
speed in ft/min (feet per minute) or m/min (meters per
minute) and not RPM. Do not use the surface speed
wheel to measure RPM. Displayed readings will be
incorrect.

MEMORYRECALL OPERATION
Note: The memory resets itself once the
START button is depressed and stable mea-
surements are displayed for 10 seconds or
12 revolutions (whichever is longer). The
values are stored when the START button is
released.
1. When you are finished taking measurements,
release the STARTbutton.
2. Depress the MEMORYbutton once, the
LAST reading will be displayed
3. Press the MEMORYbutton twice, the MAX
reading will be displayed.
4. Press the MEMORYbutton three times, the
MIN reading will be displayed.
Unit will power off after 5 seconds.
CONTINUOUS ON OPERATION
The 505L can be set to continuous on,
eliminating the need to hold the START
button down.
1 Press and hold the STARTbutton then
press the MEMORYbutton. “L-on” will dis-
play indicating continuous on is activated.
2. Deactivate continuous on by holding down
the STARTbutton and press the MEMO-
RY button. “L-off” will display indicating
continuous on is deactivated.

BATTERY REPLACEMENT
Measurement Procedure:
1. Remove the screw holding the battery compart-
ment cover in place on the back of the 505L.
2. Slide the cover off of the unit.
3. Remove the 2 each “AA” alkaline batteries and
replace with the same type.
4. Replace the cover and screw.
