System settings
On the tab
System settings
break times for the injection valve and
flow rate corrections for the high-pressure pump are defined.
Valve
Injection

Break time, ms
Modification of the break time for the injec-
tion valve.

99 ms
Pump
High pressure pump.
Flow correction
Factor for correction of the difference bet-
ween displayed and actual flow rate of the
high-pressure pump.
Range:
0.9 ... 1.25
The correction factor is determined as fol-
lows by measuring the actual flow rate us-
ing a graduated cylinder:

must not exceed 2.75 mL/min.
Ch1/Ch2 threshold
Limit for measuring channel ratio Ch1/Ch2.
Threshold, mAU
As long as the absorption value(s) from
channel 1
,
channel 2
or
both
lie beneath the
defined
Threshold
(limit) the value for the
Ch1/Ch2 ratio will not be calculated.
Analog Outputs
Settings for analog signal output.
Range, mAU
The defined value is equivalent to 1 V for
the analog signal output.
