SECTION I: Introduction
The SQA-V is a high performance analytical medical device that combines state-of-
the-art technology in electro-optics, computer algorithms and video microscopy. The
system performs a precise, 75-second semen analysis. The SQA-V runs a self-test and
auto-calibration on start-up and also runs external quality controls. The SQA-V
incorporates two systems: An automated system and a visualization system
which allows flexibility to analyze all types of semen samples.

Automated System
Motility Channel
Light disturbances caused by moving sperm cells are detected and translated
into analog signal peaks.
The greater the number of motile sperm cells in the field of view, the higher
the peak.
The slower the sperm velocity the broader the signal peaks.
The average analog signal is mathematically proportional to MSC.
Concentration Channel
Sperm concentration is measured in the cuvette section of the SQA-V testing
capillary.
An infrared light wavelength specific to sperm cells is maximally absorbed by
sperm cells and minimally absorbed by other seminal fluid components.
In the final calculation of sperm concentration the SQA-V algorithm makes an
adjustment to account for the infrared light absorption of the seminal fluid
components.

and SQA-V Service Manual 24_Apr_2014

Step 1: The capillary is inserted into the measurement compartment.
Step 2: Sample concentration is evaluated in the "tall" 10 mm chamber of the
capillary by measuring the amount of optical absorption of light as a
beam traverses the seminal fluid.
Step 3: Motility is detected in the "thin" 0.3 mm section of the capillary by
analyzing light modulations caused by sperm motion.
Step 4: This information is then digitized and routed to the microprocessor that
applies algorithms to extract the required clinical semen parameters and
performs internal self-testing and calibration.

and SQA-V Service Manual 24_Apr_2014
8
NOTE: Variations in ambient temperature may impact the accuracy of test
results because of the effect of temperature on human semen.
System is fully operational at up to 80% humidity and 26°C.
Maintenance Schedule
Daily cleaning of measurement compartment (refer to User Guide –
"Cleaning") or with each 10-15 tests and/or spillage. USE ONLY the
MANUFACTURER supplied cleaning kit, brush and solution to clean the SQA-V
or the system may be damaged and/or inoperable!
Manufacturer Recommendations
Operate the SQA-V away from devices that may cause electronic noise (cell
phones) or other devices causing vibrations such as centrifuges.
Turn system OFF at the rear-panel when not in use for extended period of
time.
When running High Sensitivity or Postvasectomy tests do not interrupt test
cycle nor interfere with system or testing capillary in any way –this test
requires complete stability of the system during the 5 minute testing cycle.
Variations in ambient temperature can affect semen samples. The SQA-V
(HUMAN) is calibrated to test samples at room temperature: 20-25ºC (68-
77ºF). All VET SQA’s are calibrated with internal heaters.
Semen is considered a biologically hazardous material and is subject to
individual laboratory protocols for handling such materials.

SECTION V: Electronic Self-Test and Auto-Calibration
Self-Test
and Auto-
Calibration
A series of tests are automatically run on the SQA-V to check the calibration and
internal operating system. Tests are run when the SQA-V is first turned-on and
also prior to each semen analysis test.
Start-up:
Stabilization and auto calibration: Checks system stability and reference
ranges. The system sensors are analyzed for several minutes to insure that the
values are within a very narrow acceptable range. Once the system is stable for 30
seconds it will pass stabilization and auto calibration. The system will fail if it is not
stable for at least 30 seconds and a warning message will be displayed.
System noise: The level of electronic noise in the system is measured to insure
that noise thresholds are accurately defined to ensure effective measurement of
electronic signals. The system will use this measurement prior to running a test
and will automatically adjust the noise level thresholds to ensure accurate
readings.
Self-test: The system produces electronic signals that simulate motility and
concentration in order to check the performance of the system and verify that the
calibration settings are consistent with the factory specifications. The
SQA-V will report failures (see section on error and warning messages) and
"freeze" the system if the system is not within the established ranges.

and SQA-V Service Manual 24_Apr_2014
12
Prior to testing a sample:
Auto calibration verification: Reference values are read again. The
concentration and motility parameters are measured (without a testing capillary).
System noise: Measures the electronic noise level of the system to insure that
noise thresholds are accurately defined in the system to ensure effective
measurement of electronic signals. The system will use this measurement prior to
running a test and will automatically adjust the noise level thresholds to insure
accurate readings.
Electronic spikes: Checks for any measurement points that are out of range
electronically. More than three such points will fault the system and a warning
message will be displayed.
The following procedure details how the user can document the system
parameters to prepare for technical support if the system fails (see section of this
user guide on Error Messages and Warning Messages).
How to run a copy of the system parameters version 2.48/2.49 GOLD:
From the MAIN MENU select: SERVICE>PRINT SQA-V DEFAULT
SETTINGS>SELF TEST DATA
All other versions:
Remove any testing capillaries from the system.
Turn the SQA-V on from rear panel and from the front keypad.
When the MAIN MENU appears or when a FAILED SELF TEST message appears
press the SERVICE key on the keypad to enter the SERVICE menu.
Select USER.
Press the PRINT key on the keypad to generate the required printout.
Refer to the table below. Enter numbers in the "SQA-V Value" column that
corresponds to #1 - #10 from the SQA-V system parameters printout. Compare
the values. If the value from the SQA-V is within range mark the "Pass" column.
If not, mark the "Fail" column.

Video
Video Screen (Part# LCD-0010)
ISSUE: A problem in the video system occurs when there is a malfunction or
maladjustment in one of these areas:
Light source, CCD camera, Harness connection, Video display monitor
To diagnose a video system problem, refer to the table below. Detailed instructions on
how to repair the problem are presented after the table.
Description of the
Video Problem
VIDEO Troubleshooting/Repair
1. Poor resolution
and dark pictures on
both the SQA-V and
V-Sperm monitors,
OR no image on both
SQA-V and V-sperm
1. Check to make sure the illumination setting of the SQA-V
is on high and the brightness setting is maximized to the
best setting. Intermittently press the illumination button on
the keypad –do not press and hold.
2. Turn the illumination button (this is the one of the blue
buttons under the video screen) since it may be set on no
illumination
3. Check the brightness settings in V-Sperm: Go to
VIDEO>Real Time Video>Settings - adjust brightness to the
best setting
4. If no improvement, check the visualization LED, if the light
indicator is on, it is working.
5. If no light is visible through the light indicator, replace the
visualization LED cable- part # KHD-908-000849-03
(detailed instructions can be found after this table).
6. If the LED is working- check the cable connecting the optical
column to the MB and to the video splitter/video adaptor/
video board:
Open the SQA-V
Check to see if all of the harness connections are secure
and tightly connected.
Check the voltage on the main board at location J9 using a
multimeter- the voltage value should be 12V. Make sure to
measure the voltage between the green and the black
wire.
If the voltage is different than 12V- replace the cable (part
# KHD-908-000853).
If the same problem persists after replacing the cable-
replace the CCD camera (part #5226, see instructions in
this manual).
