.pK: pK or HNP evaluation. Possible only in pH and U titrations.

3.2.2.25. Mode.Parameter.Presel.IReq

id1, id1&2, all, OFF

Mode.Parameter.Presel.SReq

value, unit, all, OFF

Parameters for DET, MET, SET, MEAS: Automatic inquiry after the start of the

determination. From such an inquiry, the determination continues if the re-

quested entry/entries is/are made, e.g. &SmplData.OFFSilo.Id1 (see 3.2.2.84)

or with &M $G, see 3.2.2.1.

$H is not possible in requests.

3.2.2.26. Mode.Parameter.Presel.ActPuls ON, OFF

for SET:

first, all, cond., OFF

Output of a pulse on the I/O line "Activate", see page 163.


3.2.2.27. Mode.Parameter.SET1.EP pH:

0...±20.00, OFF

U,

Ipol:

0...±2000, OFF

Upol:

0...±200.0, OFF

Mode.Parameter.SET1.UnitEp read

only

Parameters for SET: Setting the 1st endpoint as pH value, in mV (with U and

Ipol) resp. µA (with Upol). The corresponding unit can be read with .UnitEP.

If the value is on "OFF", no further nodes will appear from SET1.

3.2.2.28. Mode.Parameter.SET1.Dyn pH:

0.01...20.00, OFF

U,

Ipol:

1...2000, OFF

Upol:

0.1...200.0, OFF

Mode.Parameter.SET1.UnitDyn read

only

Mode.Parameter.SET1.MaxRate 0.01...10...150, max.

Mode.Parameter.SET1.MinRate 0.01...25.0...9999.9

Parameters for SET: Control parameters, see page 42.

.Dyn:

Dynamics, control range in pH, mV (with U and Ipol) or µA (with

Upol). The corresponding unit can be read with .UnitDyn.

.MaxRate: Maximum allowed titration rate in mL/min. Max. means maximum

possible rate with the Exchange Unit in current use.

.MinRate: Minimum titration rate in ul/min.

3.2.2.29. Mode.Parameter.SET1.Stop.Type drift, time

Mode.Parameter.SET1.Stop.Drift 1...20...999

Mode.Parameter.SET1.Stop.Time 0...10...999, inf

Mode.Parameter.SET1.Stop.StopT 0...99

999, OFF

Parameters for SET: Type and size of the stop criterion of the titration.

.Type: Type of stop criterion after stop drift or switch-off delay time.

.Drift: Stop drift in ul/min. Applies when "drift" has been selected.

.Time: Switch-off delay time in s. Applies when "time" has been selected. "inf"

means infinite.

.StopT: Stop time in s. Applies when "time" has been selected and the value of

.Time is set to "inf.".
