Introduction
RINKO FT (model name: ARO-FT, AROD-FT) is a small, fast-response, and high-precision sensor for
measurements of water temperature and dissolved oxygen (DO).
The communication method can be selected from UART (3.3V logic) and RS-232C according to the float
specifications.
Possible to attach/detach the main unit without changing the float inner pressure for calibration/inspection.
Span/zero calibration is possible by the calibration kit (optional).

3Safety Warning
Danger
Indicate[s] a hazardous situation which, if not avoided, will result in
death or serious injury. The signal word "DANGER" is to be limited to
the most extreme situations.
Warning
Indicate[s] a hazardous situation which, if not avoided, could result in
death or serious injury.
Caution Indicate[s] a hazardous situation which, if not avoided, could result in
minor or moderate injury.
Indicates general precautions.
Indicates supplements to control method and convenient functions.
Danger
Ensure safety for operations on water or ships.
Warning
Do not damage the cables.
Do not modify.
Do not use it with a power supply beyond the rated values.
Do not disassemble.
It can cause fire or electrocution.
Do not directly look at the excitation light for a long time.
It can damage the eyes.
Make Sure to Read This before Use

Caution
Do not apply strong force or impact on the sensor.
It can lead to damage, which may cause injury and seepage of water into the instrument.
Do not hang by holding only the lead wire.
It can lead to a broken wire or damaged instrument.
Make sure to insert the connector completely up to its base.
It may cause seeping of water into the instrument.
Do not leave the instrument in a place with high temperature (e.g. under direct sunlight)
for a long time.
It can accelerate the degradation of the oxygen detection film.
When attaching, make sure to tighten the screw all the way.
Loosely attached screws can compromise the water-proof property and may cause seeping of
water into the instrument.

4Precautions for Usage
Use of instrument4.1
(1) After every use, clean with fresh water, remove moisture with a soft cloth, and store securely.
(2) The oxygen detection film is highly delicate and requires handling with care. Significant damage causes
inaccurate data and requires a replacement of the oxygen detection film.
(3) When not in use, place the protection cap and turn off the power supply.
(4) Do not drop the instrument or apply impact.
(5) Before touching the instrument, release static electricity by touching a metal.
(6) As storage location, avoid places with temperature above 40 °C, high humidity, or high amount of dust.
(7) If the instrument was not used for a long time, inspect each part before connecting to the power supply.
(8) When using the instrument in water, it is recommended to use it at 30 °C or below. When it is used in
water at 30 °C or above, the tracking for correction of temperature change can slow down, requiring
more time to resume to the normal value.
(9) The insulation screw is for preventing electrolytic corrosion due to contacts between different metals.
Software4.2
(1) It is prohibited to copy or reproduce part or whole of the software without JFE Advantech’s written
approval.
(2) The content and specifications may change without notice.
(3) We try our utmost to comprehensive content, but please contact JFE Advantech for any suspicion or
suggestions.
(4) In this user’s manual, Microsoft Windows 7/8/8.1 is used for demonstrations. Computer’s control
display or method may be different depending on the environment used.
Disposal4.3
When disposing of this product, ensure to abide by law and regulations.

Attaching and detaching the attachment/connectors5.2
5.2.1 Standard type (ARO-FT)
(1) How to attach
Make sure that the O-rings are free of dust.
Insert slowly so as not to warp or pinch the O-rings.
Before use, check if the connector is inserted to the point you cannot turn it any more.
Incomplete insertion can cause damage to the instrument due to the seepage of water.
(2) How to detach
Pulling out the hex bolts disassembles the lock-nuts, then you will be able to detach.
Before attaching again, apply adequate amount of grease on the O-rings.
When detaching, hold the metal part and pull it out. Pulling only the cable can break it.
Insert the connector into the main unit until two black
O-rings are completely hidden. Hold it in while going to
the next step.
Attach a half of the two lock-nuts,
while pushing the connector and the main unit towards to each
other. When you do so, make sure that the red O-ring is squashed (almost invisible) by the connector
and the main unit.
Red O-ring is completely exposed.
Gap: approx. 0.5 mm
While holding them together, place two lock-nuts and
temporary fix the position by using two hex-bolts
(M3×10) just enough to combine two lock-nuts into
one. Screw the Lock-nut tightly onto the main unit to
the point you cannot turn it any more. Then, tighten the
two hex bolts completely.

5.2.2 Cable type (ARO-FT)
(1) How to attach
Make sure that the O-rings are free of dust.
Insert slowly so as not to warp or pinch the O-rings.
Before use, check if the connector is inserted up to its base. Incomplete insertion can
cause damage to the instrument due to the seepage of water.
(2) How to detach
It can be pulled out by loosening the locking sleeve.
Before attaching again, apply adequate amount of grease on the O-rings.
When detaching, hold the metal part and pull it out. Pulling only the cable can break it.
Insert the connector into the main unit until two black
O-rings are completely hidden. Hold it in while going to
the next step.
Tighten the locking sleeve up to its base while pushing the
connector against the main unit (see below).
Check if the screw thread is completely hidden.
Thread is completely hidden. Thread is visible.
OK NG

5.2.3 MCBH type (AROD-FT)
(1) How to attach
Before use, check if the connector is inserted up to its base. Incomplete insertion can
cause damage to the equipment.
(2) How to detach
It can be pulled out by loosening the locking sleeve.
Before attaching again, apply adequate amount of grease on the O-rings.
When detaching, hold the connector and pull it out. Pulling only the cable can break it.
Insert the connector into the main unit until
there is no gap between.
Tighten the locking sleeve up to its base while
pushing the connector into the main unit.

6Maintenance and Inspection
Before use6.1
(1) Check that the sensor surface is free of any foreign object.
(2) Check that there is no loose or damaged connector or screw.
(3) Span/zero calibration is recommended before use.
(4) Make sure to remove the protection cap before use.
Maintenance after use6.2
(1) After use, clean well with fresh water. If something cannot be removed by water, gently remove it with a
soft cloth. Rubbing it hard can damage the oxygen detection film.
(2) After water cleaning, remove the moisture either by an air blower or by wiping with a soft cloth.
(3) Check if there is no scratch or damage on the sensor.
Storage6.3
(1) For storing, avoid places with high temperature, high humidity, or direct sunlight.
(2) Place the sensor protection cap when storing in order to protect the sensor and prevent degradation.
(3) Avoid places with temperature higher than 40 °C as it can cause output error or degradation of the
oxygen detection film.
