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 µA, 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:

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

µA)

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 µA, OFF)
