• Test Mixer? This entry determines if the mixer is clear of
obstructions and operating properly. It will mix
a sample for approximately five seconds and
display an error message if any problems are
encountered.
• Test Filter Wheel? This entry determines if the filter wheel is able
to select the filters properly. It will allow a
selection of one of two filters (520 nm or 730
nm). If the filter wheel cannot be positioned to
the selected filter, an error message will be
displayed.
• Read Temperature? This entry displays the PCS temperature as
determined by the probe in the vial block.
NOTE: Should the probe be disconnected (as might happen if the rear access cover is
removed for instrument service and not properly re-installed), the PCS will beep
at power-on and indicate that there is a temperature probe error.
• Test Switches? This entry checks the lid open/closed switch
and the vial-in-place sensor. Failure of either
sensor will make it impossible to use the PCS
normally.
