2.6.2 Parameters for SET
SET1, SET2:
Control parameters for EP1 and EP2.
titration parameters
are valid for the global titration sequence.
stop conditions:
Parameters for the termination of the titration.
statistics :
Calculation of mean values and standard deviation,
see page 77.
preselections :
ON/OFF of various auxiliary functions such as auto-
matic requests after the start and activate pulse.

Control parameters for EP1 or EP2, resp.
Preset EP1 (input range depends on the measured
quantity:
pH: 0...±20.00, OFF
U, Ipol: 0...±2000 mV, OFF
Upol: 0...±200.0 µA, OFF)
sets "OFF".
If EP1 is "OFF", no further inquiries under SET1 appear.
Distance from EP where constant dosing should stop
and controlling begins. (control 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 µA, OFF)
sets "OFF".
"OFF" means largest control range, i.e. low titration.
Outside the control range, dispensing is performed
continuously, see also page 31.
Maximum dosing rate (0.01...150 mL/min, max.)
sets "max.".
This parameter determines primarily the addition rate
outside the control range, see also page 31.
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
