To unlock this file you must key in the code that
was used to lock the file. You may not edit a locked
file, so the Edit soft-key is replaced by the View
soft-key, which allows you to browse through the
contents of that file, without making any changes.
However, you are permitted to copy a locked file.
After copying the original file remains locked but the
copied file is unlocked automatically by the software.
Direct Manipulations (MAN)
You can either perform one of three direct manipu-
lations (Prime, Measure, Titrate) by pressing the
corresponding soft-key. Press the Man soft-key, the
Action Screen appears.
Prime
You should prime the 402 before each run, to ensure
that all fluid pathways contain fresh solvent.
Press Prime, Initialization Screen 2 appears.
Put the probe-end of the transfer-tubing into a
suitable waste container, then press OK.
Priming starts immediately and the message
‘Priming ...’ appears on the screen; during which
time solvent is expelled at the probe-end of the
transfer-tubing.
Press STOP, or the End soft-key, when you are
satisfied that all fluid pathways have been primed
with fresh solvent and that there are no bubbles in
the tubing.
Pressing End
When you press End, the motion of the syringe(s)
ceases and ‘Homing ...’ appears on the screen until
the syringe(s) have returned to their uppermost
positions.
Pressing STOP
You can press STOP at any time, however, this key
is more for use if a problem arises (such as a leak).
When you press STOP, the motion of the syringe(s)
ceases and the Abort Screen appears. Press Proceed,
when you want to continue the prime from the point
at which it was stopped (for example, to refill the
solvent reservoir).
