2.7 Parameters, key <PARAM>

The key <PARAM> is used for the entry of values that

determine the modes. Values marked with "cond." are

accessible during the conditioning in the SET mode.

"**titr." means that these values can be changed dur-

ing the titration. They influence the ongoing determina-

tion. Other values can only be changed in the inactive

state.

The display texts of the Titrino are shown to the left.

The values are the default values.

2.7.1 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 also page 41.

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)

<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 µA, 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.
