Safety Notes

DANGE R

This instrument is designed to comply
with IEC 61010 Safety Standards, and has
been thoroughly tested for safety prior to
shipment. However, mishandling during
use could result in injury or death, as
well as damage to the instrument. Be
certain that you understand the
instructions and precautions in the
manual before use. We disclaim any
responsibility for accidents or injuries not
resulting directly from instrument
defects.

This manual contains information and
warnings essential for safe operation of
the instrument and for maintaining it in
safe operating condition. Before using it,
be sure to carefully read the following
safety precautions.

Overvoltage Categories

This instrument complies with CAT I
safety requirements.
To ensure safe operation of
measurement instruments, IEC 60664
establishes safety standards for various
electrical environments, categorized as
CAT I to CAT IV, and called overvoltage
categories. These are defined as follows.

____________________________________________

____________________________________________

CAT I: Secondary electrical circuits connected to

CAT II: Primary electrical circuits in equipment

service entrance, and to the power meter
and primary overcurrent protection device
(distribution panel).

Higher-numbered categories correspond
to electrical environments with greater
momentary energy, so a measurement
device designed for CAT III environments
can endure greater momentary energy
than a device designed for CAT II. Using
a measurement instrument in an
environment designated with a higher­numbered category than that for which
the instrument is rated could result in a
severe accident, and must be carefully
avoided.

Accuracy

We define measurement tolerances in
terms of f.s. (full scale), rdg. (reading)
and dgt. (digit) values, with the following
meanings:

f.s. (maximum display value or scale length)

The maximum displayable value or scale
length. This is usually the name of the
currently selected range.

rdg. (reading or displayed value)

The value currently being measured and
indicated on the measuring instrument.

dgt. (resolution)

The smallest displayable unit on a digital
measuring instrument, i.e., the input value
that causes the digital display to show a
"1" as the leastsignificant digit.

Notes on Use

Follow these precautions to ensure safe
operation and to obtain the full benefits
of the various functions.

DANGE R

To avoid damage to the instruments and
potentially life-threatening hazards,
observe the following precautions:
Be careful when measuring with the
contact adapter because rotation and
vibration of the instrument can produce
erratic results with either high or lo w
rotation speeds. Hold the main body
firmly against the rotator. Do not place
the instrument on a tripod when making
measurements.
If the contact tip is not fully inserted over
the contact adapter shaft, it could fall off
the shaft by touching the rotator. Make
sure the contact tip is firmly inserted over
the adapter shaft before making
measurements.

____________________________________________

____________________________________________

7

WARNING

To avoid damage to the instruments and
potentially life-threatening hazards,

observe the following precautions:
Always use the screw to tighten the
contact adapter to the main body. If it
becomes loose, the instrument may
vibrate or be dislocated and become a
hazard.
When using the contact adapter for
measuring, the instrument is subject to
vibration, so measurements should be
made only below 20,000 r/min or 333 r/s.
Use either the specified Hioki 9035 AC
ADAPTER or another 300 mA/6 V adapter
with 5-mm diameter and negative center
contact that complies with IEC 60950
safety standards.

CAUTION

Do not store or use the instrument where it
could be exposed to direct sunlight, high
temperature or humidity, or condensation.
Under such conditions, the instrument may
be damaged and insulation may deteriorate
so that it no longer meets specifications.
To avoid electrical hazards and damage to
the instrument, do not apply voltage
exceeding the rated maximum to the output
terminals.

____________________________________________

8

____________________________________________

NOTE

Depending on the material of the object
to be measured or method of touching
the contact tip, the measurement error
may occur.
Do not perform measurements in
locations with high humidity or where
those are subject to intense ambient
light.
Avoid scratching or dirtying the two
lenses inside the detector window.
Do not switch between FAST and
SLOW modes when the instrument is
set to the MAX or MIN hold
measurement mode. (3404 only)

Overview

1.1 Product O verview

This instrument is a non-contact, highly
portable tachometer that functions by
measuring the visible light reflected from
reflective tape attached to the object to
be measured. It can also be used as a
contact type tachometer by attaching the
optional 9213 CONTACT ADAPTER,
sold separately.

Measurement Method

2.1 Measurement Preparations

1. If this is the first time the instrument
will be used, insert the batteries.

2. Attach the reflective tape to the
rotating object.

Before attaching the tape, make sure
that the surface of the object is free of
dirt, grease or dust.

3. Turn on the power switch, and check
that all segments of the display light
for about one second.

If the mark lights, replace the
batteries.

4. Turn the detector window so that the
red emitted light faces the reflective
tape on the rotating object. If the
reflected light is being detected, the
buzzer sounds and the LED lights.

If the reflectivity of the rotating object
itself is high and light is reflected from
portions other than the reflective tape,
tilt the instrument to restrict the
incident light and obtain a more
accurate reading.

____________________________________________

Chapter 2 Measurement Method

14

____________________________________________

NOTE

The red light from the instrument shall
strike the reflective tape at an incidence
angle of 45 degrees or less. If the
incidence angle exceeds 45 degrees,
the instrument may not be able to
detect the reflected light and may not
be able to do measurement.

2.2 Normal Measurement

1. When the power is turned on, the
instrument will automatically enter the
normal measurement mode.

2. The speed of rotation of the object will
be measured and displayed.

The speed of rotation range can be
switched between r/min and r/s during
measurement. The 3404 can also be
switched between FAST and SLOW
sampling period.
On the 3403, the last digit of the
display will be fixed to 0 for counts
over 20,000.
Analog output on the 3404 will match
the displayed value.
For speed of rotation measurement
under 30 r/min in the 3404 SLOW
mode or on the 3403 or for
measurement under 120 r/min in the
3404 FAST mode, the display will
appear as indicated right.

The display will appear as "

NOTE

When the count exceeds 20,000 on the

zero. This is the same for MIN and MAX
hold modes as well.
During r/s measurements, accuracy of
values greater than 1600 r/s is not
assured.

Precautions

Precautions in Measurement of
High-Rotation Objects

Detection of reflected light uses
modulated light to minimize the effects of
incident light. When this modulated light
is input for a fixed period of time (about

0.2 ms) or longer, a single pulse is
detected. For this reason, if the light
pulse generated by the passing reflective
tape is less than 0.2 ms detection is not
possible.
The range that can be detected with a
12 mm 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.

Analog output is the conversion of the
displayed rotation speed to mV,
multiplied by the selected
magnification.
Minimum resolution for analog output
is 1 mV, regardless of range. In other
words, in the x 0.1 mV magnification
analog output is in 10 r/min steps; and
in the x 0.01 mV magnification, it is in
100 r/min steps. in the x 10 mV
magnification, analog output is in 0.1
r/s; and in the x 1 mV magnification, it
is in 1 r/s steps.
Analog output will convert measured
results for each sample (D/A) for
stable output even at low rotation
speeds. The sampling rate will be
changed when the measurement is
switched between FAST and SLOW
modes, allowing the optimum mode for
specific applications to be selected.
Sampling is 0.7 to 2.0 s in the SLOW
mode, and 0.12 to 0.5 s in the FAST
mode.
In r/s measurement, maximum output
is 1000 r/s, as even in the x 1 mV

The analog output is sent out during

the NORMAL, MAX HOLD and MIN

When using the MAX, MIN and

not held constant, but remains the
same as during normal measuring.
