A. RPM Measurement (See Figure 3)
zDo not point laser directly at eyes.
zTo avoid the rotating object touching the meter and cause any injury
or damage to the meter during the measurement, please keep the
meter more than 50mm away from the tested target.
Measurement Operation
Figure 3
To carry out RPM measuremnet, follow the
following procedure:
Attach a piece of reflecting tape to the
object under test.
Position the meter firmly on desired location.
Hold the meter and keep its light source 50~
200mm away from the object under test.
Press ON/OFF button, the Meter is default to
enter the RPM measurement mode. Point the
Tachometer light source to reflective tape,
The deviation from the ideal right-angle
should not be greater than 30.
The LCD displays the RPM reading.
Note:
When measuring RPM, the LCD displays “0.0000”
if there is no signal within 7 seconds.
When the RPM is greater than 99999.
the LCD displays OL.

B. Counts
Self-lighted Counts (See Figure 4)
1. Position the meter firmly on desired location.
Hold the meter and keep its light source
50~200mm away from the targets.
2. Press the ON/OFF button
3. Press the R/C button to select Count mode.
4. Point he Tachometer light source to the objects
under count. The deviation from the ideal
right-angle should not be greater than 30.
5. The LED scans the objects under count,
counts the number and displays the total
value.
Note:
1.The object under count must be reflective,
otherwise Counts feature cannot be used
Receiving Light Source Outside (See Figure 5)
Figure 5
Position the meter firmly on desired location.
Hold the meter and keep its light source 50~
200mm away from the targets. The deviation
from the ideal right-angle pointing should not
be greater than 30.
Locate the Meter, objects under counts and light
source as shown in Figure 5
Press ON/OFF button
Turn the LED off, refer to page 9 point B.
Then press R/C button to select Counts mode.
When the objects under count pass between the
meter and light source, the meter count the number
and display the total value.
Note:
Under the count mode, when the total count
the Meter displays OL and hold the data.
Press M/M/A button to zero the Counts.
Press ON/OFF to re-start Counting.
