Running the Didymium Filter Test
The didymium filter can be used to check the wavelength accuracy of the UltraScan PRO. This check
should be done on a regular basis (i.e., weekly or bi-weekly) as part of your routine instrument
performance check.
To perform the wavelength check, follow the steps described in the
DIAGNOSTICS > SENSOR MENU
in
the EasyMatch QC Manual.
Replacing the Source Lamp
The xenon flash lamp provides over one million flashes. When the lamp no longer flashes or instrument
repeatability has become unacceptable, it must be replaced.
CAUTION: Replace only with a specified xenon flash lamp assembly, HL#D02-1012-222.
Figure 32. Source Lamp Assembly
Before you attempt to change the source lamp, ensure that the UV filter is out. If the UV filter is left in,
the filter may be broken during the process of removing and re-inserting the bezel. Check the current
standardization mode. If the mode indicates that the filter is in a position other than
Nominal
, you
must re-standardize the sensor in a mode with the UV filter nominal. (The filter can also be manually
removed from the path, if necessary, by a trained representative of HunterLab.)
To change the source lamp:
1.
Disconnect the UltraScan PRO from its power source.
2.
Wait two minutes for complete discharge of the capacitors.
3.
Disengage and remove the sample clamp.
4.
Loosen the two screws on the front cover with a flat-head screwdriver.
