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.
