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.

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:

10 Safety Information

TM-4100/TM-4100D

In some cases, work in the vicinity of
powerful radiation sources can be a risk of
your life.
Be aware that persons with electronic
implants (e.g. cardiac pacemakers) are
subject to particular dangers in some cases.
Observe the local safety regulations of the
facility operation.

Observe the operating instructions for
equipment, which is used to generate,
conduct, or consumer electromagnetic
energy.
Be aware that secondary radiators (e.g.
reflective objects such as a metallic fence)
can cause a local amplification of the field.
Be aware that the field strength in the near
vicinity of radiators increases proportionally to
the inverse cube of the distance. This means
that enormous field strengths can result in the
immediate vicinity of small radiation sources
(e.g. leak in wave guides, inductive ovens)
Field strength measuring device can
underrate pulsed signals. Particularly with
radar signals, significant measurement errors

DANGER

24

TM-4100/TM-4100D

can arise.
All field strength measuring devices have a
limited specified frequency range. Fields with
spectral components outside of this frequency
range are generally incorrectly evaluated and
tend to be underrated. Before using field
strength measuring devices, you should thus
be certain that all field components to be
measured lie in the specified frequency range
of the measuring device.

11 End of life

Caution :

This symbol indicates that
equipment and its accessories shall
