A Note identifies the information that user should pay attention to.

Warning

- Before using the Meter inspect the case. Do not use the Meter if it is damaged or the case (or part of the case) is removed. Look for cracks or missing plastic.

- Do not use or store the Meter in an environment of high temperature, humidity, explosive, inflammable and strong magnetic field. The performance of the Meter may deteriorate after dampened.

- Do not point laser directly at eye.

- Replace the battery as soon as the battery indicator 📄 appears. When the battery is between 4.5V \~4.8V, the battery indicator 📄 appears. When the battery is between 4.3V \~4.5V, battery indicator 📄 linking, the Meter will be turned off after 1 minute.

- When opening the battery door, make sure the Meter is powered off.

- When servicing the Meter, use only the replacement parts with the same model or identical electrical specifications.

- The internal circuit of the Meter shall not be altered at will to avoid damage of the Meter and any accident.

- Soft cloth and mild detergent should be used to clean the surface of the Meter when servicing. No abrasive and solvent should be used to prevent the surface of the Meter from corrosion, damage and accident.

- Turn the Meter off when it is not in use and take out the battery when not using for a long time.

- Constantly check the battery as it may leak when it has been using for some time, replace the battery as soon as leaking appears. A leaking battery will damage the Meter.

Measurement Operation

Warning

• To reserve battery, the USB feature will be automatically off when the Meter is restarted. The other setting remains unchanged.
• The Time will be off after the HOLD feature is enabled. The time will be on again after existing HOLD mode.

A. RPM Measurement (See Figure 3)

Warning

• Do not point laser directly at eyes.
• To 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.

To carry out RPM measuremnet, follow the following procedure:

1. Attach a piece of reflecting tape to the object under test
2. Position the meter firmly on desired location. Hold the meter and keep its light source 50\~200mm away from the object under test.
3. 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°.
4. The LCD displays the RPM reading.

Note:

1. When measuring RPM, the LCD displays "0.0000" if there is no signal within 7 seconds.
2. 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

Figure 4

Receiving Light Source Outside (See Figure 5)

1. 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°.

2. Locate the Meter, objects under counts and light source as shown in Figure 5

3. Press ON/OFF button
4. Turn the LED off, refer to page 9 point B.
5. Then press R/C button to select Counts mode.
6. When the objects under count pass between the meter and light source, the meter count the number and display the total value.

Note:

1. Under the count mode, when the total count
   the Meter displays OL and hold the data
2. Press ON/OFF to re-start Counting.
