On the right side of the screen, the open ports of the flow path switching valve
connected to the instrument are displayed. In the previous figure, the connection address
of the system controller is set to A. When the low-pressure gradient valve is used, the
set ports open only during delivery. While delivery is stopped, the screen displays
"OFF".

Display Auto-Diagnostics Status
Diag Off
The delivery status is not being
judged. This is displayed while
delivery is stopped or when not
being analysed etc.
Diag Monitoring
Judgment of the delivery status is
in progress.
Diag NotDetected Delivery failure was not detected.
Diag Detected Delivery failure was detected.
Auto-Diagnostics issues a
warning if a pulse exceeds a
specific threshold.
Note that very slight pressure
variation may not be detected.
The table shows a guideline of the conditions under which the Auto-Diagnostics function
can correctly detect a delivery failure.
