UltraScan PRO Maintenance and Testing
The UltraScan PRO does require some maintenance. This section outlines the parts of the UltraScan
PRO you must maintain for the instrument to function properly and tests you may run to assess its
performance.
Note: Do not disassemble the instrument and attempt to clean the optical
components. Do not open the instrument or remove any covers except using the
instructions given in this User’s Manual, the EasyMatch QC help
file, or under the
direction of HunterLab Technical Support
.
Running the Repeatability Test
You may test the repeatability of your instrument as follows:
1.
Turn the UltraScan PRO on and allow it to warm up for two hours. Meanwhile, clean the
white tile and allow it to return to room temperature.
2.
Follow the instructions given in the
SENSOR MENU > DIAGNOSTICS
section to run the
repeatability test that is built into EasyMatch QC.
Running the Green Tile Test
The green tile is not used during the standardization process. Instead, the green tile is used to verify
the long-term performance of your instrument. Perform the green tile test as described in the
SENSOR
MENU > DIAGNOSTICS
section once a week. You can then examine all green tile readings periodically
and see any trends that develop over time.
The UltraScan PRO should be in its standard configuration, RSIN mode with the large area view port
plate installed and UV filter nominal, when these readings are made. The illuminant and observer used
in your display must match those on the green tile. The green tile test will configure these job settings.
Figure 31. Green Tile
The green tile reading should vary by no more than
0.15 XYZ
units from the values given on the tile. If
your reading is out of this specification, first clean the standard tiles. Then standardize and measure
