important information that the user should read be-
fore using the instrument.
The symbol printed on the instrument indicates
that the user should refer to a corresponding topic in
the manual (marked with the symbol) before us-
ing the relevant function.
Indicates DC (Direct Current).

ing manner.
Indicates that incorrect operation presents
an extreme hazard that could result in se-
rious injury or death to the user.
Indicates that incorrect operation presents
a significant hazard that could result in
serious injury or death to the user.
Indicates that incorrect operation presents
apossibility ofinjury totheuser ordamage
to the instrument.

We define measurement tolerances in terms of f.s. (full scale),
rdg. (reading) and dgt. (digit) values, with the following meanings:
Accuracy
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 val-
ue that causes the digital display to show
a “1” as the least-significant digit.

Follow these precautions to ensure safe operation and to obtain
the full benefits of the various functions.
Before using the instrument the first time, verify that it operates
normally to ensure that no damage occurred during storage or
shipping. If you find any damage, contact your dealer or Hioki
representative.
• Although this instrument is dust resistant, it is not completely
dust- or waterproof. To prevent possible damage, avoid using
in dusty or wet environments.
• The protection rating for the enclosure of this device (based on
EN60529) is *IP50.
*IP50:
This indicates the degree of protection provided by the enclo-
sure of the device against use in hazardous locations, entry of
solid foreign objects, and the ingress of water.
5: Protected against access to hazardous parts with wire mea-
suring 1.0 mm in diameter. Dust-proof type (The penetration
of dust cannot be prevented completely, but quantities of dust
that may hinder the stated operation of equipment or safety
cannot penetrate the enclosure.
0: The equipment inside the enclosure is not protected against
the harmful effects of water.
Operating Precautions
Before use
Before using the instrument, make sure that the insulation on
the cable is undamaged and that no bare conductors are
improperly exposed. Using the instrument in such conditions
could cause an electric shock, so contact your dealer or Hioki
representative for repair.
Setting up the instrument

6
Instrument Installation
To avoid damage to the instruments and potentially life-
threatening hazards, observe the following precautions.
• Use only the specified/supplied Model Z1004 AC Adapter.
AC adapter input voltage range is 100 to 240 VAC (with
±10% stability) at 50/60 Hz. To avoid electrical hazards
and damage to the instrument, do not apply voltage out-
side of this range.
• Before turning the instrument on, make sure the supply
voltage matches that indicated on the AC adapter. Con-
nection to an improper supply voltage may damage the
instrument or AC adapter and present an electrical haz-
ard.
• If the protective functions of the instrument are damaged, either
remove it from service or mark it clearly so that others do not
use it inadvertently.
• To avoid damage to the instrument, protect it from physical
shock when transporting and handling. Be especially careful
to avoid physical shock from dropping.
• To avoid breaking the cables, do not bend or pull them.
• For safety reasons, when taking measurements, only use the
L9094 Output Cord provided with the instrument (FT3406
only).

Storage temperature and humidity:
-10°C to 50°C (14 to 122°F), 80%RH or less (non-condensating)
Accuracy guarantee for temperature and humidity:
23°C±5°C (73°F±9°F), 80%RH or less (non-condensating)
Rotational speed measurement
Avoid the following locations that could cause an accident or damage to
the instrument.
Exposed to direct
sunlight
Exposed to high
temperature
In the presence of cor-
rosive or explosive
gases
Exposed to water,
oil, other chemi-
cals, or solvents
Exposed to high
humidity or con-
densation
Exposed to strong
electromagnetic fields
Near electromagnetic
radiators
Subject to vibra-
tion Nearinductionheating systems
(e.g., high-frequency
induction heating sys-
tems and IH cooking
utensils)
Measurement Precautions
Always wear protective eyewear as debris from the rotating
object may cause injury.
• Depending on the material of the object to be
measured or method of touching the contact tip,
the measurement error may occur.
• Avoid scratching or dirtying the two lenses inside
the detector window.

8
Using the Contact Adapter
Handling contact tips
Analog Output Terminals and Pulse Output Terminals
• 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.
• Be careful when measuring with the contact adapter
because rotation and vibration of the instrument can pro-
duce erratic results with either high or low rotation speeds.
Hold the main body firmly against the rotator. Do not place
the instrument on a tripod when making measurements.
• When using the contact adapter for measuring, the
instrument is subject to vibration, so measurements
should be made only below 19,999 r/min or 333 r/s.
• When using the Contact Adapter, do not mount the instru-
ment on a tripod.
• Verify that the contact tip has been inserted sufficiently
into the adapter axis before beginning measurement. Fail-
ure to insert the contact tip sufficiently into the adapter
axis may cause it to separate from the axis, contact the
rotating object, and fly off in the vicinity of the object.
• If the contact tip is able to come into contact with the
rotating object, exercise caution when winding it onto the
object.
• Do not allow rubber contact tips to come into contact with
hot measurement targets. Doing so may cause the con-
tact tip to melt.
To avoid electrical hazards and damage to the instrument,
do not apply voltage exceeding the rated maximum to the
Analog Output Terminals and Pulse Output Terminals.

This portable, contactless tachometer uses reflected visible-
spectrum light to measure the speed of a rotating object to which
reflective tape has been affixed. It can also be used as a con-
tact-type tachometer by attaching the Z5003 Contact Adapter.
Overview Chapter 1
1.1 Product Overview
1.2 Features
Contactless measurement for long detection range
The instrument’s ability to detect speed from up to 50 cm distance al-
lows its use in situations where itwould be hazardous to approach the
object being measured.
Easy-grip design
Easy-to-grip design and light weight make the instrument easy to han-
dle.
LCD with a wide field of vie
The FT3405/3406 features a transmissive FSTN liquid crystal display
(LCD), ensuring its readout is easy to read.
Maximum/minimum value hold
Maximum and minimum values are updated continuously so you can
verify variations in rotational speed.
Dust-proof design
The FT3405/3406’s enclosure delivers IP 50-grade protection, allow-
ing it to be used with confidence and peace of mind in environments
characterized by debris (dust, sand, grit, etc.) thrown off by the rotat-
ing object.
Drop Proof
The FT3405/3406 can withstand being dropped from a height of 1 m,
making it less likely the unit will be damaged.
Analog Output/ Pulse Output (FT3406 only)
The FT3406 can be used in trend management applications by con-
necting it to a recorder.
