[4] DESCRIPTION OF FUNCTIONS
4-1 Power button:
Press and hold the button for more than one second to turn the
instrument ON.
All of the display and indicators light up and then the instrument
gets ready for measurement.
* If there is a reflective object in front of the lens when the instrument
is turned ON, a numeric value may be displayed. In such a case,
wait for about 2 seconds until the numeric value becomes [0].
(Ready for measurement)
Press the same button for more than one second to turn the
instrument OFF.
The measurement mode setting is saved in memory even after the
instrument has been turned OFF.
4-2 Auto power OFF
When the instrument has not detected reflected light for about 2
minutes after the last operation performed, the instrument turns
OFF automatically. To recover from the auto power OFF status,
turn the instrument ON with the usual procedure.
To cancel the auto power OFF function, press and hold the
button and then hold the Power button for more than one second
to turn the instrument ON. The indicator will not be displayed in
the measurement display.
4-3 Measurement mode selection: button
Each press of the button switches the measurement mode.
Press and hold the button for more than one second. The
indicator appears indicating that the instrument is in the noncontact
measurement mode. To return to the contact measurement mode,
press and hold the button for more than one second again.
* For details on the measurement mode switching of the noncontact
an d co n ta ct m ea s u re m e n t m o d es , s e e “ 5 - 3 No n co n t a ct
Measurement” and “5-4 Contact Measurement”.
4-4 Backlight switching: button

the display and the numeric value being displayed is held. The
displayed value will not change even when the measurement input
varies. When the button is pressed again, the indicator
disappears and the data hold function is canceled.
* The data hold function is also canceled when the button is
pressed.
4-6 Maximum and minimum value display:
button
Press the button to enter th mode in which the e
instrument saves and stores the maximum and minimum measurement
values from the moment the button is pressed. Each press of the
button switches the displayed values in the following cycle:
• Maximum value display: The instrument displays the maximum
value since the press of the button.
• Minimum value display: The instrument displays the minimum
value since the press of the button.
• Current value display: The instrument displays the current
measurement value while saving the maximum and minimum
values since the press of the button. To view the
maximum or minimum value, it is required to press the
button to the maximum or minimum value display.
To cancel the maximum and minimum value display, press and
hold the button for more than one second.
* The maximum/minimum value display function is also canceled
when the button is pressed.
* The button is disabled during data hold ). The (
maximum and minimum values are not updated during it.
* Maximum and minimum value display function is disabled in the
count measurement mode.
4-7 Count clear: button
Press the button during count measurement (unit: count)
clears the counted value.
4-8 Low battery alarm
When the battery power is consumed and the voltage drops below
about 2.3 V, the indicator appears on the display panel to
solicit early replacement of the batteries.
4-9 Tripod hole
The instrument can be installed on a
commercially available tripod for fixed
use. Screw in the tripod into the
threaded tripod hole on the rear of the
instrument.
• Thread size: 1/4-20 UNC (ISO 1222)
* Use a commercially available tripod.
[5] MEASURING PROCEDURE
5-1 Start-up inspection
Inspect the following points before starting the work of every day.
• Appearance: Check that the appearance of the instrument is not
damaged by falling, etc.
If any irregularity is found, do not use the instrument.
• Scratches and dirt on the lens: Check that the lens is not
clouded.
Accurate measurement is impossible if the lens is dirty or clouded.
Dirt or cloud should be removed by gently wiping with a soft, dry cloth.
• Check that the low battery alarm indicator is not displayed
when the instrument is turned ON. If it is displayed, replace the
batteries with new ones.
* If nothing is displayed on the display panel, the batteries could be
exhausted completely.
5-2 Warning for measurement
1. Do not measure a rotating object from a close distance at
which the instrument could contact the rotating object.
2. Do not attempt to measure an object rotating at a speed
exceeding the measuring range of the instrument.
WARNING
5-3 Noncontact measurement
Be sure to stop the rotating object to be measured before
attaching the reflective sticker on it.
WARNING
1. Before attaching the reflective sticker on the rotating object,
remove the moisture, oil and dust on the sticker attaching
surface completely.
2. If the sticker is to be attached on a shiny plated surface,
accurate measurement would be impossible due to diffuse
reflections. In this case, paint the sticker attaching surface
black or attach a piece of black tape on the surface.
3. Protect the reflective sticker on the rotating object against
penetration of intermittent light such as the light from a
fluorescent lamp. If an effect of extraneous light is expected,
adjust the positioning of the instrument so that it displays [0]
when the rotating object is not rotating before measurement.
4. Accurate measurement may sometimes be impossible under
direct sunlight.
5. Measurement of high-speed rotation may be impossible of
the time the irradiated light passes on the reflective sticker is
short (less than about 0.2 second). In this case, increase the
area of the reflective sticker.
CAUTION
To perform noncontact measurement, attach the reflective sticker
(provided with the instrument) on the rotating object to be
measured as shown below.
Rotating object
Reflective sticker
Irradiation light
1) Turn the instrument ON and set the desired measurement mode.
Each press of the button switches the measurement
mode in the following cycle:
Rotation speed measurement Rotation speed measurement
(revolutions per minute) (revolutions per second)
Rotation count measurement Interval measurement
(counts) (milliseconds)
2) Apply the irradiation light perpendicularly on the reflection
marking on the rotating object so that the rotation detection
indicator LED lights steadily. The distance between the tip of the
detection section of the instrument and the reflective surface on
the rotating object should be between 50 and 500 mm.
3) The instrument displays the measurement result.

5-4 Contact measurement (Using the optional ENC-3)
1.
Do not perform measurement if the contact adapter, contact
maker or rim speed ring of the contact measurement attachment
is damaged, worn or deformed.
2. Be sure to tighten the contact adapter fixing screw tightly.
3. Fit the contact maker or rim speed ring all the way into the
root of the rotary shaft of the contact adapter.
4.
When measuring a high-speed rotating object (8000 rpm or
higher), do not measure it continuously for more than one minute.
5. Do not use a tripod in the contact measurement.
6. Do not use the contact maker or rim speed ring with a high-
temperature rotating object.
WARNING
The contact measurement required the optional ENC-3 Contact
Measurement Attachment.
1) Attach the contact adapter as shown below and secure the fixing
screw tightly. Contact adapter

2) Select the contact maker or rim speed ring according to the
purpose of measurement and fit it on the tip of the contact
adapter.
Contact maker
Rim speed ring
* Select the rim speed ring when measuring the velocity of a belt
conveyer or similar object (Travel distance per minute in m/min or
travel distance per second in m/s).
3) Turn the instrument ON and select the contact measurement
mode (see “4-3 Measurement mode selection”). Ensure that
the indicator appears on the display panel and set the desired
measurement mode.
Each press of the button switches the measurement
mode in the following cycle:
Rotation speed measurement
Rotation speed measurement Interval measurement
(revolutions per minute) (revolutions per second) (milliseconds)
Rim speed measurement Rim speed measurement Rotation count measurement
(meters per second) (meters per minute) (counts)
When the rim speed ring is attached, select either the [m/min] or
[m/s] mode.
4) Apply the contact maker or rim speed ring on the rotating object.
Special care is required for the method of application.
The contact maker should be applied perpendicularly to the
contact surface toward the axis of the rotating object.
The rim speed ring should be applied in parallel with the
measurement target.

5) The instrument displays the measurement result.
6) Detach the contact adapter by loosening the fixing screw,
position the instrument so that the side with the fixing screw
faces down and pull the adapter obliquely considering the
presence of a lock mechanism.
