2.4 Safety Precautions for Operators
Before using this Instrument, make sure that the Instrument
was installed by authorized personnel.
If the Instrument is not installed correctly, it could break down
or cause fire, electric shock or injury.
Check the following points before starting operation. These
checks are necessary in order to prevent accidents and injuries.
the warning labels are legible
the ground connection is fully secured
A broken power cable could result in electric shock, fire, and
short circuit. Observe the following points.
the cable is not twisted
the cable is not caught by pressure between the Instrument
and the wall.
the cable is not bent too tight
nothing is put on the cable
the cable is not tied in a bundle
the cable is not modified
the cable is kept away from any heater.
the plug itself, not the cable, is gripped when unplugging the
cable
Dust accumulated on the power plug can start a fire. Check the
plug regularly and remove dust.
Insert the power plug firmly into the socket. Poor contact could
cause overheating, burn injuries and fires.
Do not get the power cable or plug wet, or electrical shock and
short circuit may result.
Never touch the power plug with wet hands, or electric shock
may result.
Using the power cable plug (plugging it in and unplugging it) to
turn the power on and off may cause the plug to overheat.
Always use the power switch (or the Main Breaker).
Warning
HM-JACKarc Operation Manual
Safety Precautions
2 - 4 Rev.4
Only use consumables and replacement parts (including
screws) that are specified by Kyowa Medex Co., Ltd.
Before cleaning the Instrument, turn the power off and be
sure to remove the power plug from the socket.
In the event of any malfunction of the Instrument, turn the
power switch off immediately and remove the power plug
from the socket. Leaving faults unattended can cause
accidents and fires.
Do not turn the power switch off and on repeatedly.
The Mixing Spatula, Sample Pipette and Reagent Pipette
attached to the injection assembly are sharp and could
cause injury.
The ends of the Mixing Spatula, Sample Pipette and Reagent
Pipette attached to the injection assembly come into direct
contact with Samples (stool samples) and Reagent. Incorrect
handling of those parts could cause infection with
pathogens or poisoning with Reagent. Wear medical rubber
gloves while working, and take extra care to avoid infection.
Warning
HM-JACKarc Operation Manual
Safety Precautions
2 - 5 Rev.4
2.5 Safety Precautions for Maintenance
Do not modify the Instrument without permission. Modification
could cause unexpected hazards.
Use consumables and replacement parts (including screws)
only specified by Kyowa Medex Co., Ltd.
Before servicing the Instrument or removing any of its parts
(fixing faults, replacing parts, inspecting, repairing, etc.), turn
the power switch off and be sure to disconnect the power plug
from the socket to avoid getting electric shock.
When disconnecting the power plug from the socket, always
grip and pull on the plug itself, not on the cable.
Use fuses of the only specified type. Use of non-specified fuses
could cause the Instrument to malfunction or, in some cases,
start a fire.
Using the power cable plug (plugging it in and unplugging it) to
turn the power on and off may cause the plug to overheat.
Always use the power switch (or the Main Breaker).
This Instrument weighs approximately 56 kg. Handle it with
extra care when moving. Note that moving the Instrument
should be done by two or more people.
The ends of the Mixing Spatula, Sample Pipette and Reagent
Pipette attached to the injection assembly are sharp and could
cause injury.
The ends of the Mixing Spatula, Sample Pipette and Reagent
Pipette attached to the injection assembly come into direct
contact with Samples (stool samples) and Reagents, so
incorrect handling of those parts could cause infection with
pathogens or poisoning with reagents. Wear medical rubber
gloves while working, and take extra care to avoid infection.

2.6 Waste Materials Precautions
Samples could be contaminated with pathogens etc., so take
extra care to avoid infection when handling them, by wearing
medical rubber gloves etc.
Before handling sample containers, reagents and buffer, read
and understand the Instructions for Use. Handle them with care
to avoid accidents.
Any Mixing Spatula, Sample Pipette and Reagent Pipette which
has been detached or removed is sharp and dangerous. Handle
them with extra care.
The ends of the Mixing Spatula, Sample Pipette and Reagent
Pipette attached to the injection assembly come into direct
contact with samples (stool samples) and reagents. Incorrect
handling of those parts could cause infection with pathogens or
poisoning with reagents. Wear medical rubber gloves at all
times while working, and take extra care to avoid infection.
Here below is a list of Waste materials generated by regular analysis.
They should be handled as medical waste and disposed of by a
specialist contractor.
Liquid waste
Used cells
Reagents and reagent bottles
Buffer and buffer fluid bottles
Used stool sample containers
Hemoglobin standards before and after preparation
Hemoglobin standard containers
Used sample cups
Control samples before and after preparation

2.7 Instrument Safety Device
Overcurrent Protection
2 or more ampere of current (input voltage 220v) will be interrupted
immediately by internal breaker and the power will be shut down.
Transformer Secondary Fuses
A fuse is installed to protect Control PCBs (Main PCB, Power PCB) from
overcurrent.
Thetransformer is protected from overheating by a thermal fuse.
A fuse is installed to protect the lamp from overcurrent.
Outer Cover Opening Check Sensor
If the outer cover is open, the Analyzer does not start motion. If the outer
cover is opened while the Analyzer is in motion, an error occurs and the
Analyzer will stop sampling. There are 2 switches to secure the function.
2.8 Noise Level of the Analyzer
The maximum noise level is 70db.
2.9 Note for Supplied Water and Detergent
Temperature of supplied water
The temperature of supplied water for this Instrument should be in
20-30 . Lower temperature of water may cause malfunction of
instrument wash, and higher one may damage the tubing and lead to
leakage of water.
Amount of use of Detergent
The amount of use of Detergent (water include 0.1% of detergent) is
approximately 4.5mL per a test. It is also used in priming and wash. It is
necessary to keep enough amount of prepared Detergent during the run.

3 Outline of Analyzer
3.1 Characteristics of the Analyzer
3.1.1 Outline
This Analyzer measures the amount of human hemoglobin present in
a stool sample.
Compact and light analyzer designed for installation in a small space.
Barcode reading input is applied to register Sample ID, Calibration
Master Curve and Calibrator Information to make the operation easier
for operators.
A two-point calibration method is adopted to simplify the measurement
operation.
The measurement method is Latex Agglutination, which is quick and
achieves superior sensitivity.
Superior detection sensitivity realizes smaller volume of stool sample
and less smell.
The sample loading capacity of the Analyzer is 80.
Reaction Cells are replaced after use automatically.
The Sample Collection Picker achieves superior stability for human
hemoglobin, reduces the decline in the amount of human hemoglobin
and enables more accurate measurement.
Analysis results can be checked on the screen and printout. Also,
connection to a host computer enables data to be exported.

3 - 2 Rev.4
3.1.2 Principles of Operation
The Reagent Pipette aspirates the Latex Reagent, which then move to a
Cell on the Reaction Table, where it is dispensed together with the Buffer.
Next, the Reaction Table Rotates and the Cell containing the Reagent
moves to the sampling position. The Sample Pipette aspirates a Sample,
which is then dispensed to the Cell. The Mixing Spatula then turns
counterclockwise to mix the Reagent and the Sample together.
The Cell containing the Reagent and the Sample moves to the detection
position after a period of time set under the measurement conditions, and
the first photometric measurement (ISTT1) is performed. After another set
period of time, the second photometric measurement (ISTT2) is
performed.
The amount of change in the Integrating Sphere Turbidity of the two
photometric measurements (ΔIST=ISTT2-ISTT1) is calculated by the
computer according to the calibration curve to output the measurement
result.
This series of actions is repeated to measure all samples placed in the
sample rack.
