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.

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.

* Monitoring batteries refer to the batteries for use in checking the
functionality and performance of the product.
1
Using a Phillips screwdriver, loosen the retaining screw of the
battery cover.
2
When the battery cover comes up, remove it.
3
Replace both of the two batteries in the battery holder with new
ones by taking care of the polarity.
4
Attach the battery cover and secure the retaining screw.
6-4 Cleaning and Storage
1. The instrument is not resistant to volatile solvents and should not
be wiped with lacquer thinner or alcohol. When it gets dirty, wi pe
dirt away with a soft cloth moistened with a small amount of water.
2. The instrument is not resistant to heat and should not be

the contact maker and rim speed ring are added to this figure above.
* In the rim speed measurement, ±0.5 % rdg is added to the figure above.
Accuracy calculation method
Example) Noncontact revolution speed measurement (rpm)
Displayed value: 10000 rpm
Accuracy: Error: ±(10000 rpm x 0.03 % + 1 dgt) = ±4 rpm
True value: Within the range of 10000 rpm ±4 rpm (9996 – 10004 rpm)
* AT 10000 rpm, 1 dgt corresponds to 1 rpm.
