Meter Operation

RPM Measurements

1. Apply a small piece of reflective tape to the object under test as shown below.

2. Point the meter's photo source at the tape on the object and press the easure button. Hold the

meter from 2 to 6" (50 to 150mm) from the reflective tape depending on ambient light.

3. Check that the onitor icon flashes on the LCD indicating that the meter is sensing a reflection

from the tape. If the monitor does not appear check that the light source is hitting the reflective

tape at a 90

angle.

4. Release the easure button when the display stabilizes (2 seconds approx.). Note the LCD

RP reading.

5. If the RP value is < 50, apply additional pieces of reflective tape (four pieces are shown

below). Divide the LCD reading by the number of reflective tapes to compute the actual RP

(Actual RP = Reading / 4).

Memory Record and Recall

The meter automatically records the Minimum and Maximum readin s. These represent the lowest

and hi hest readin s measured from the moment the Measure button is pressed to the moment it is

released. The Last readin is also recorded; this is the last measurement taken before the Measure

button is released. These stored readin s can be displayed on the LCD usin the Memory button as

described below:

1. Press once and hold: The Last readin is displayed followed by "LA"

2. Press a ain and hold: The Maximum value is displayed followed by the word "UP"

3. Press a ain and hold: The Minimum value is displayed followed by "dn"

Special Measurement Considerations

1. The non-reflective area of the object under test must always be reater than the reflective tape

area.

2. If the shaft of the object under test is reflective, it should be covered with black tape or paint

before attachin reflective tape.

Battery Replacement

The low battery indication appears as "LO" on the display. To replace the batteries:

1. Slide the rear cover off the battery compartment in the direction indicated by the arrow.

2. Replace the four 1.5V 'AA' batteries and the battery compartment cover.

3. Remove the batteries if the instrument will be stored for lon periods of time.
