ZEISS Matrix 800
ZEISS · Model Matrix 800
Connects to office networks, EHRs and FORUM®. Frequency Doubling Technology – detects damage to the M-cells, a subset of ganglion cells. Large, age-related normative database. Fast and easy to use –no darkened room required. No trial lenses or eye patches required. Fits in any practice –compact and portable. Offers reports similar to those of the Humphrey HFA, the World Standard of Care.
Key tips
- ·Verify laser output with a real power meter, not the unit's own display - the display can drift independently of true output.
- ·Take "the image looks a little off" reports seriously - optical alignment drift is usually gradual, not sudden.

168WARNING! Selected test will be permanently deleted from the database. Continue?
User confirmation needed. Deleting tests from the database is permanent. Unrecoverable if not available from a prior backup.
175Patient not found in database. Add New Patient?
User confirmation needed. The automatic search feature did not find a patient with the name entered in the database – either new patient or a data entry error.
176Unable to run test during calibration.
Wait until calibration is completed. All testing operations are disabled during calibration. Check Calibration status in Help (F6) Calibration screen. Calibration takes approximately 15 minutes to complete. SW error if message doesn't go away when calibration is completed. (restart).
192Sample test is not present on the system. Function unavailable.
• The file /root/GUI/printSample.fdt2 is missing • The file /root/GUI/printSample.fdt2 could not be loaded for various file I/O reasons. Try again. If problem persists, send customer update (from web site?) which includes necessary file. If after upgrade, problem still is present may need service but if this is the case, the customer should be seeing other issues with the system as well.
196What would you like to do with these tests?
If the user highlighted the tests and selects the Edit test option on the F3 screen The user decides to either move the selected tests to a different folder OR move the test association to another patient.
197Are you sure you want to reassign these NUMBER_OF_TESTS tests?
If the user highlighted the tests and selects the Reassign Test option. The user decides to reassign the selected tests to another patient.
202The character AN_INVALID_CHARACTER cannot be used as a text delimiter.
While in the Save As Dialog box, the user attempts to assign a delimiter which is invalid. Invalid characters include: (the double quote, ") Specify a different delimiter. Reboot and try again. If persistent, use a predefined delimiter and report error to developers.
238This operation is not available. Because the network host was not available the file write test could not be attempted.
Verify that the Matrix and the shared PC are connected to the network. If both are connected make sure file and print sharing are enabled on the PC are turned on and that the appropriate folders and printers have been shared.
239Please enter a name for the printer. Give the printer selected a reference name.
240Please enter a valid hostname or IP address
Ask the operator to enter a shared network computer host name or ip address (computer1.cznet.org, 128.115.68.2). This message is no longer used. Enter in a hostname (mypc.domain.com) or IP address (128.68.24.2).
241Please select a path for the printer.
Asks the operator to specify the location of the network shared printer. This message is no longer used. The printer is now selected graphically. Enter the path to the network shared printer (//mycomputer.domain.com/HP6920).
262The device is busy and cannot safely be removed.
The storage device is currently being used for read or write operation. Wait for the operation to complete before trying to remove the storage device. If this situation persists, try rebooting the Matrix. The period of time required to wait will depend on the operation performed. Backup or export of a large number of patients and tests will take a long time.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Optical / illumination fault (dim, uneven, no illumination; slit / filters not working)
- Replace the bulb / LED module with the correct type and wattage.
- Check the power supply and the brightness / rheostat control.
- Clean the illumination and viewing optics per the manual.
- Confirm the slit, filters and apertures operate.
- Replace the power supply if output is still low.
Symptom: Alignment / positioning-stage fault (joystick or slide binds, chin-rest drive)
- Check the stage ways for debris or dried grease.
- Inspect the stage bearings / slides for wear.
- Check the chin-rest / table actuator and its switch.
- Re-lubricate or replace the stage / drive kit.
- Confirm smooth motion and that it holds position.
Symptom: Measurement or capture fault (reading errors, calibration fails, poor image capture)
- Run the instrument self-test / calibration.
- Clean the measurement window / objective.
- Verify against a model eye / test target where one exists.
- Confirm patient positioning and fixation.
- Refer the sensor / camera module if calibration will not hold.
Symptom: Printer / PC / connectivity fault
- Check the built-in printer and paper.
- Confirm the PC, network and EMR interface settings.
- Restart the software and the instrument.
- Send a test result.
- Escalate a persistent interface fault to the OEM.
