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
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.

* In the statistics memory mode, the statistics data in a single registration is calculated from the measurement value for up to 100 times
of display update. When the display update frequency exceeds 100 in a single registration, memory registration automatically ends.
*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

(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.

Rear panel
Battery cover
*Use AA type alkali or manganese batteries. When other types of batteries are used, operation cannot be guaranteed.
* In the following cases, the settings and/or memory data may not be saved normally: when the battery level is low, when removing batteries
during operation, when disconnecting the USB cable (option) during use at the time of the power supplied only through the USB cable.
When the battery indicator
blinks, open the battery cover
on the rear panel, and replace
batteries.
Put in two new batteries, aligning the
positive and negative polarities correctly,
and close the cover.
・Do not mix and use new and old
batteries, or dierent types of batteries.
・Failure to follow this may result in injury
and/or damage due to leakage. When
you do not use the unit for a long period
of time, remove batteries, and keep
them in the carrying case.
