FINE
This repeatedly turns on and off the purge solenoid valve to remove air bubbles
trapped in the flow cell. The term Purge Cycle is used for the length of one
purge cycle. The default setting is 30 seconds.With this setting, the valve
remains on for 15 seconds and off for another 15 seconds. Choose preferred
setting (Custom) if necessary.
This sets the number of the purge cycle.
At the end of the purge cycles, the auto-zeroing should be made.
This defines the length of the pause period between the end of the
purge cycles and the auto-zeroing.
80 min
This is a period in which the detector is equilibrated for the
measurement of drift and noise performance.
80 min
This is a period in which drift and noise performance is measured
after reaching equilibrium.
