Meter Operation

Photo Tachometer Measurements

1. Apply a square piece of reflecting tape to the surface of the object under test.

2. Point the top of the meter toward the device under test at a distance of 2" to 79" (50

to 2000mm).

3. Press the Measure button (located on the right side of the meter) and align the

laser pointer beam with the reflective tape.

4. Verify that the Monitor Indicator appears on the upper left hand section of the LCD

when the object under test passes through the light beam

5. Release the Measure button when the RPM reading stabilizes on the LCD.

6. If the rpm is under 50,apply additional squares of reflective tape. Divide the

reading shown on the display by the number of reflective squares to get the actual

rpm.

NOTE: Bright ambient light may interfere with the reflected light beam. Shading the

target area may be necessary in some cases.

CAUTION: Rotating objects can be dangerous. Use extreme care when holding the

meter near any such object.

MIN/MAX and Last Reading Memory Recall

The 461923 can record Maximum, Minimum, and Last Reading for the period of time the

Measure button is held. These stored values can then be read directly on the meter's display.

Access the memory data immediately after the measurements have been taken.

1. Press once and hold: The Last Reading is displayed followed by the "LA" icon.

2. Press again and hold: The Maximum value is displayed followed by "UP" icon

3. Press again and hold: The Minimum value is displayed followed by "dn" icon
