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 fac tor is determined as
follows by measuring the actual flow rate
using 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
