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 uA, OFF)

<CLEAR> 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 uA, OFF)

<CLEAR> 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.)

<CLEAR> 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:
