2.6.4 Parameters for STAT

control parameters:
for reaching the control point.
titration parameters
control the global course of the titration.
stop conditions:
Parameters for automatic termination of the titration.
statistics:
Calculation of mean values and standard deviation,
see page 77.
evaluation:
Evaluation of rates, fix volumes and fix times.
monitoring
of limit values for the measured value, temperature and
rate.
preselections:
ON/OFF of various auxiliary functions such as auto-
matic requests after the start and activate pulse.

Control parameters

Control point: (input range depends on the measured

quantity:

pH:

0...±20.00, OFF

U, Ipol:

0...±2000 mV, OFF

Upol:

0...±200.0 uA, OFF)

<CLEAR> sets "OFF".

Controlling range (input range depends on the

measured quantity:

pH:

0.01...20.00, OFF

U, Ipol:

1...2000 mV, OFF

Upol:

0.1...200.0 uA, OFF)

<CLEAR> sets "OFF".

"OFF" means largest control range, i.e. always

controlled reagent addition.

Outside: constant dosing, see also page 51.

Maximum dosing rate (0.01...150 mL/min, max.)

<CLEAR> sets "max.".

This parameter determines primarily the addition rate

outside the control range, see page 51.

The maximum rate depends on the Exchange Unit:
