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 valve.
Break time, ms Modification of the break time for the injec-
tion valve.
Entry range:
1 ... 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:
Flow correction =
Displayed flow rate
Measured flow rate
The product of parameter Flow correction
and parameter Flow (on the tab Controls )
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.
Entry range:
0.1 ... 2000.0 mAU
