stop pH OFF
**titr.
stop EP 9
**titr.
filling rate max. ml/min
**titr.
Stop at measured value (input range dependent on
measured variable:
pH: 0... ± 20.00, OFF
U, Ipol: 0... ± 2000 mV, OFF
Upol: 0... ± 200.0 uA, OFF)
sets "OFF".
"OFF" means that the criterion is not monitored.
Stop after a number of EP's have been found (1...9,
OFF)
sets "OFF".
"OFF" means that the criterion is not monitored.
Filling rate (0.01...150 mL/min, max.)
sets "max.".
The maximum rate depends on the Exchange Unit:
Exchange Unit max.
5 mL 15 mL/min
10 mL 30 mL/min
20 mL 60 mL/min
50 mL 150 mL/min

Equivalence point criterion (input range depends on
mode.
For DET:
0...200
For MET:
pH: 0.10...9.99
U, Ipol: 1...999 mV
Upol: 0.1...99.9 uA)
Threshold for the size of the jump, see page 23.
Recognition of EP's which fulfill the EP criterion. (all,
greatest, last, window, OFF)
Selection of equivalence point recognition:
"all": All equivalence points are recognized.
"greatest": Only the greatest (steepest) equivalence
point is recognized.
"last": Only the last equivalence point is
recognized.
"window": Only EP's in specified windows are
recognized.
"OFF": Evaluation switched off.
If "window" is selected, lower and upper limits of
windows are inquired.
Lower limit of window 1
and
upper limit of window 1
(Input ranges for both inquiries depend on the
measured quantity):
pH: 0...±20.00, OFF
U, Ipol: 0...±2000 mV, OFF
Upol: 0...±200.0 uA, OFF)
