Instruction Manual
Thank you for purchasing Nidec-Shimpo's Handheld High-Performance Digital
Tachometer DT-2100. For instructions on how to use this product properly and
optimally for a long period of time, please be sure to read this manual thoroughly
before use.
Safety Requirements
Be sure to observe
Before operation, maintenance and inspection, please carefully read this instruction manual
and follow it for proper use. Start using only after you have read about the equipment’s func
tions, safety information and precautions.
This instruction manual provides three grades of safety warnings: "Danger", "Warning" and
"Caution". Each of them is an important description related to safety. Be sure to follow them.
Non-contact type digital tachometers are used to perform
measurement by applying the supplied reflection tape
to the rotating body of the object to be measured, and
projecting the laser beam (red) to the tape. In addition, they
can be used for contact type measurement by attaching the
supplied contact adapter.
■Inspection result certicate
We skip issuance of the inspection result certicate for this product. However, at the
time of factory shipment total shipment inspection has been completed, and we have
strictly conrmed that there is no error in measurement accuracy and operation.Your
understanding is appreciated.
Before operation, maintenance and inspection, please
carefully read this instruction manual and follow it for
proper use.
After carefully reading this manual, be sure to store it in a safe
and convenient place for easy reference.

the object to be measured
Re ection tape
Apply the supplied reflection tape to
the rotating body of the object to be
measured.
●Do not apply to a rotating body smaller than
the re ection tape.
●If the rotating body is glossy, apply black tape,
or paint it black and apply the reflection
tape.
●Before applying the re ection tape, wipe off
water/oil on the attachment surface of the
rotating body, and apply the tape without
any irregularities.
Point the laser beam irradiation
2
port to the object to be measured
Point the laser beam irradiation port
to the reflection tape applied to the
rotating body.
●Keep a distance of 50 to 4000 mm (2 in.
to 13 ft.) between the reflection tape and
irradiation port.
Press the power/measurement key

contents selection, and set to "1. Contact" in the "5. CONTACT" setting.
* When using the speed measurement wheel, in the "8. DIAMETER" setting of "3. SET_SYSTEM" in contents selection, set the
diameter value of the peripheral speed foil. When using the supplied speed measurement wheel (circumference of 6 inches),
use it with the default value (diameter value of 48.5104 mm).
to be measured
Carefully put the speed
measurement wheel on the object
to be measured (belt part, etc.).
Press the power/measurement
key, and start measurement
Refer to the above (rotation speed
measurement)
■Precautions on measurement and handling
Before measurement, securely t the contact adapter to the contact. Also, during measurement, carefully put the contact on the rotating body of the
object to be measured.
When attaching the speed measurement wheel for measurement, align it along the object to be measured, and do not push the wheel with excessive
force. Also, for safety measurement, use with a speed of 300m/min (500cm/s, 18000m/h, ～18km/h, 197inch/s) or less.
When measuring a high-speed rotating body using the conical or funnel contact over a long period of time, note that the convex and concave portions
of the contact may produce high heat.

*The statistics memory mode can be used only when one of the units from "rev/min" to "miles/h" is selected in the unit setting.
5-2. Memory registration in the memory group
Start memory registration from the start memory group (that has been set in "3. START_MEM" of "2. SET_USER" in contents selection).
・
When the number of memory groups reaches the number of memory sets in each group (that has been set in "4. MEM_GROUP" of "3. SET_
・
SYSTEM" in contents selection), the memory group switches to the next one.
When the number of memory sets exceeds the total number of memory sets for all memory groups, "FULL" is displayed in the unit display
・
part. In this case, additional memory cannot be registered.
Example: When the start memory group is set to memory group 2
(1) Start memory registration from
the start memory group
Group 1 Group 2 Group 3 Group 5Group 4
(2) Go to the next memory group
when the number of memory
sets exceeds the specied
number
(5) Displays "FULL" when the number of memory sets exceeds the specified number for all
memory groups, and ends memory registration ("FULL" is displayed until the operation key 1 is
pressed)
After that, even if you press the operation key 1 and try to start memory registration, "FULL" is
displayed for 1 second, and registration is disabled.
(3) Go to the next memory
group when the number
of memory sets is 0
(4) Return to memory group 1
when the number of memory
sets exceeds the specied
number in group 5
