Introduction
2.1 Brief Description of the Operational Characteristics of the AMAX CS-190
The AMAX CS-190 is a fully automated coagulation instrument.
The AMAX CS-190 is used for measuring the in-
vitro coagulation times. Both plasma and whole blood samples can be used.
The instrument features an optical and a mechanical measuring unit.
In addition to the clotting tests, chromogenic (kinetic) tests can be carried out by using the optical measuring unit.
The measured results can be converted to concentration or activity data with the help of storable standard curves.

The PC identifies and stores patient samples and data.
The samples are aspirated from their primary
containers with a needle by way of the XYZZ­robot probe. Then the samples are mixed in a measuring cuvette with either a reagent and/or a buffer. After that the samples are incubated in the incubation rail (12 incubation slots).
At the end of the incubation period, the XYZZ­robot moves the cuvette into the optical or mechanical measuring unit.

After the addition of the starting reagent by the XYZZ-robot, the coagulation time is measured.
Reagents, volumina and incubation periods can be programmed individually.
Measured results and their calculations can be printed out in a protocol and stored
simultaneously in the PC’s patient archive.
In addition, the results can be transferred to an external EDP (laboratory EDP) via bidirectonial data transfer.

3.1 Information on How to Avoid Danger to Life and Health
3.1.1 General Information
If the AMAX CS-190 shows any defects which might endanger patients or user
personnel, it must not be operated (§ 6(1) MedGV).
Wear protective clothing, especially protective gloves. It is a possibility that infected
plasma (dangerous substances) might be touched.
Protective clothing, especially protective gloves which were in contact with
dangerous substances (e.g. infected plasma) have to be changed and disposed immediately (Technical rules for dangerous Substances (TRGS)).
Plasma samples, reagents and waste water are toxic waste. The toxic waste has to
be disposed in compliance with the operative regulations (laboratory regulations).
3.1.2 Information on the Repair of the AMAX CS-190
While under repair the instrument must not be used for testing.
After a repair, the AMAX CS-190 has to undergo a functionality check. This involves
the carrying out of checking measurements. These actual values have to be equivalent to the theoretical values.
ATTENTION!
Live parts (power unit and connection panel) must not be
touched!
DANGER TO LIFE!
ATTENTION!
On certain parts (photometer lamp or lamp casing) there is a
DANGER OF BURNS!
IMPORTANT!
Regular maintenance helps to avoid malfunctions and protects

Measuring Methods
The AMAX CS-190 features a mechanical and an optical measuring unit. The mechanical measuring unit has 4 measuring cells which work with the ball method.
The optical measuring unit (photometer) has 4 measuring channels for measurement of the optical density. The wavelength of the light is 405nm.
The necessary total volumes for the measurements are:
Mechanical measuring mode,
Optical measuring mode
Maximum volume (mechanical, optical): 600µl
The individual measuring modes are described on the following pages.
minimum volume: 75µl
, minimum volume: 150µl
6
6.1 Mechanical Measuring Mode
The time between the addition of the starting reagent and the beginning of the formation of fibrin is measured.
The sample and if necessary the reagent and/or buffer are pipetted into a measuring cuvette. After the incubation time it is placed into one of the mechanical measuring channels automatically.
There is a special steel ball on the bottom of the cuvette.
With the addition of the starting reagent, the cuvette starts to rotate around its longitudinal axes while the ball is held in a certain position by a magnet.
As coagulation begins, the ball is removed from its position by the forming fibrin threads, because the force of the magnet is overcome. A sensor detects the change of the ball’s position and ends time measurement.

Measuring Methods
Impulse measurement
In order to detect very unstable clots with the mechanical method, the continuous rotation of the cuvette can be changed to a rotation with intervals after a predefined time. In the example on Pic 6.1.2, the continuous movement is switched to interval movement after 25.6s. During the intervals, which prolong automatically, a clot cannot be detected, but it has time to stabilise itself. The CV rises in dependence with the length of the interval.

6.2 Optical Measuring Mode (Clotting)
The time between the addition of the starting reagent and the beginning of the formation of fibrin is measured.
The sample and if necessary the reagent and/or buffer are pipetted into a measuring cuvette. After the incubation time it is placed into one of the optical measuring channels automatically.
The timing begins with the addition of the starting reagent. The intensity of the light beam that passes through the cuvette is monitored by a sensor. When clots are forming, the sample/reagent mixture becomes cloudy and the intensity of the light reaching the sensor decreases (turbidimetrical measurement).
As soon as the change in the optical density reaches a pre-set threshold, the time measurement stops.

Measuring Methods
6.3 Optical Measuring Mode (Chromogenic)
The rate of absorbance change is measured at predetermined intervals.
Sample and reagent are pipetted into a measuring cuvette and placed into one of the optical measuring channels. After the addition of the starting reagent, measurements are taken in defined intervals.
A monochrome light beam (405nm) passes through the cuvette. The change in optical density is measured by a sensor behind the cuvette at pre-defined intervals (kinetic measurement).
The values of change in mE/t are further mathematically processed.

7.2 Installation of the AMAX CS-190
1. Remove the packaging material of the AMAX CS-190 and level the instrument on the base cabinet.
Fasten the connecting bolts which connect the base cabinet and the instrument.
2. Do not turn on the instrument yet!
All movable parts were secured for transport. (XYZZ-robot: all axes were secured) Remove all shipping clamps. (check driving belt XY-axes, tapes, paper boards, etc.) Check all movable parts for free movement.
3. Check the system coolant level,
if necessary fill up with original system liquid. (830040 (500ml bottle)).
4. Configure PC & Accessories.
5. Connect the fresh/waste water reservoir and the liquid level sensors.
6. Establish all electrical connections between the PC and the AMAX CS-190.
7. Now the AMAX CS-190 can be turned on.

ATTENTION!
Remove all shipping clamps and securing devices before turning
on the instrument.
Disregard may lead to malfunction of and cause damage to the
AMAX CS-190!
Packaging material is recycable!

1. Remove all packaging material of the PC, monitor, printer, etc. In case the AML-Bus-Board (Board PH-PC (D02801)) or the modem board (Z04005)
have not yet been installed, the PC has to be opened and the boards have to be placed into free slots.
Check and correct the jumper settings (see below) before the installation. Disregard
may lead to malfunction or conflicts with other components.
2. Connect all components (except for the PC and the AMAX CS-190!) and establish all electrical connections.
3. Install the software:
First, switch on the PC, screen and printer. The PC installs its operating system
automatically (selection: WINDOWS 3.1) After approx. 30 min. the installation is complete and you can continue by yourself. Deinstall WINDOWS with only the DOS prompt remaining on the hard drive.
Now the main software can be installed. It consists of three or five 3,5” disks: a. Disk with main menu AMAX CS-190 b. Disk for service software c. Disk for AMAX CS-190 (instrument specific data) d. Disk for modem software (option) e. Disk for printer driver
(printer specific)

7.3.1 Jumper Settings on the AML-BUS-PC-Board
There are two dip-switches on the Board PH-PC for adjusting the address. The following switch adjustments have to be made so that the board can be identified:

7.3.2 Jumper Settings of the Modem Boards
The different modems are not distinguishable by their names. For their differentiation, the BZT-No. is used here. This BZT-No. is printed on the packaging and on a label on the modem itself.
