Standalone Diagnostics consist of the following tests:
1 – Touch Screen Tests (Calibration, Pixel Sensitivity, Emulation) 2 – Keyboard Test (Echo of all keys, including function and control keys) 3 – Serial Devices (AT4 and M&D Loopback, Printer and Lab Computer Config) 4 – Sensor Tests (A/D Reads, Optical Sensors, Heat Pumps)
5 – Motor Tests (Stepper Motors, Bidirectional DC Motors, Fans)
6 – S/W Version ID Numbers (MIC ROM, Flash, Slave ROM, EEPROM, Analog, PAL) 7 – REC Board Tests (Elec. & Reflec. loopbacks and control line toggles)
To initiate Standalones, touch "RETURN" twice to go back to the Diagnostics Menu and then the Main Menu. When in the Main Menu, touch the target "Exit to Boot Menu," and "y" when prompted by "Do you want to continue? Y/N".
The analyzer will then proceed to close any open files and reset the Scheduler Computer. When the Vitros Boot Menu appears, select the touch target

Loopback Tests
Loopback Tests
The loopback test lets you verify the operation of any of the three output device ports for either printer or the lab computer interface (LCI). This is useful in determining the cause of a malfunction in printer or LCI operation by testing the basic functionality of the analyzer ports. If the test passes, it indicates the port is fine and you should check the port configuration in the Options dialogue and/or the cable or output device for a solution to the malfunction.You will need to use the loopback connector TL-3225 (part of the spare parts kit).
To run loopback tests:
1. Touch EXIT TO BOOT MENU on the Main Menu.
2. Type “Y” and press the Enter key on the keyboard at the prompt,
“This will exit to the Boot Menu. Do you wish to continue?” It will take a few minutes for the Boot Menu to display.

Sample Metering
Details on how to run each performance test are found on the following pages.
Sample Metering
Two sample metering performance tests are available:• Leak/Hysteresis Test—Performs a sequence of four checks: A/D reference voltage check, transducer check, leak test, and hysteresis test.
— The A/D reference voltage check reads and displays the A/D converter output.
— The transducer check monitors and displays the pressure as voltage values while the sealed tip is subjected to a series of aspirations followed by a series of dispenses.
— The leak test verifies that a closed or sealed system can be created in the sample metering assembly when the proboscis picks up a tip, aspirates, and dispenses a sample.
— The hysteresis test measures the ability of the pump (over its full range) to return to its initial value after a set of dispense/
aspirate actions. The pump is the portion of the sample metering assembly that causes the pressure changes.
(Hysteresis is a physics term that indicates the ability or inability of a stressed system to return to its original state when the cause of stress is removed.)
The four checks are carried out in the order in which they are listed above. You can end the leak/hysteresis test after completing each check or continue with the next check in the sequence. If you choose to stop the leak/hysteresis test before all four checks have been completed, you must start the test from the beginning to perform the checks missed. For instance, you cannot go directly to the leak test without first doing the A/D reference voltage check and the transducer check.
• Drop Detection Test—Verifies that the sample metering drop detection and the slide recognition sensor are functioning properly.
This sensor must tell the analyzer a drop of sample was dispensed on the slide and a slide is actually present in the slide block to accept a sample drop.

You can use these performance tests to verify or assess the operation of the incubator disk and those mechanisms that control it.Two incubator performance tests are available:
• Incubator Pad Reflectance—Verifies that there is a consistent level of reflectance from one incubator pad to the next in the incubator. This ensures accurate and precise slide readings for any test located in any incubator nest position.
• Incubator Position Timing—Verifies that the nest-to-nest rotational timing is consistent for all nests on the incubator disk. This also verifies that the aperture in each nest is present and centered over the reflectometer read station at a constant time interval for slide readings to be taken. This ensures accurate and precise slide readings for any test located in any incubator nest position.
Testing Incubator Pad Reflectance NOTE: The white and black correction factors must be set before this test will run correctly. Refer to the “Rate/CM Correction Factor Test” in the “Setup/Adjust” section earlier in this chapter.
To test the incubator pad reflectance:

NOTE: The Positive Sample Identification (PSID) Scanner is an optional accessory.Two PSID scanner performance tests are available when a PSID scanner is installed:
• Tool Side Tests—Checks the performance of the PSID scanner by reading the bar code samples at the limit of the specification and reporting the number of scans necessary for a good read. You will need the PSID Alignment Tool, TL-4531, to perform these tests.
• User Samples Test—Checks the quality of sample bar codes you generate by reporting the number of scans necessary for a good read. This test can assist you in diagnosing a malfunction that may be caused by the print quality of your bar codes.
