Appendix B
Distributor Test
The distributor positions the sample tube over the appropriate bottle during
multiple bottle sampling. If the distributor arm is obstructed or if a problem
exists with the distributor assembly, the arm will not position over the desired
bottle correctly.
This test assumes that 24 bottles are installed which is the most difficult to
position for the distributor (the most stops and the smallest bottle mouth).
Upon selecting the Distributor Test, the arm returns to the bottle #1 position
then moves one bottle at a time for all 24 bottle positions. The arm then
reverses direction and again stops at all 24 positions on its way back to the
bottle #1 position. Make sure no obstructions interfere with the distributor
arm rotation.
Event List
The Event List diagnostic provides a time/date stamped list of significant
events occurring in the sampler. You can review these events to find out when
an event occurred and what events preceded or followed the event of interest.
Events may be viewed in chronological order from the beginning or end of the
event list by selecting View From Start or View From End.
The event list cannot be erase, even when the program is started. Up to 200
events are logged before the list wraps around and the oldest entry is
discarded as each new entry is posted.
Logged events include:
Keypad Test
Keypad Test provides a simple means of verifying the operation of all front
panel keys. Select Keypad Test from the diagnostics menu to bring up the
following screen:
Pressing any key on the front panel (except for the upper left soft key) will
cause that key label to appear in the center of the display.
All numeric keypad keys, soft keys, and function keys may be tested in this
manner. To end, press
QUIT (this also verifies the upper left soft key
operation).
