read this user’s manual before you operate it.
2 Features
Measurement method: Using red visible
spectrum light source and reflective tape or a
reflector plate.
Reflex indicators : When you receive the
reflected signals the RING bright LCD screen
locked. The buzzer.
Features : Max / Min display, display hold, on
average, automatic shutdown, buzzer,

EMC
This meter was designed in accordance with EMC
Standards in force and its compatibility has been
tested in accordance with EN61326-1 (2006).
zAc / The pulse output wiring diagram:
6 Measurement Procedures and
Preparation
Precautions in Measurement of High-Rotation
Objects Detection of reflected light uses
modulated light is input for a fixed period of time
(about 0.2ms) or longer, a single pulse is detected.
For this reason, if the light pulse generated by the
passing reflective tape is less than 0.2ms
detection is not possible.
The range that can be detected with a 12mm
square target of reflective tape is indicated below.
※Radius is the distance between the center of
the rotating object and the center of the tape.

TM-4100/TM-4100D

Chapter Measurement Procedures
If the reflective tape cannot be attached within this
detection range, increase the area of the reflective
tape so that the generated pulse is 0.2ms to
higher.
For measurement of 30,000r/min. or higher, uses
the following method:
