3.2.2.30. Mode.Parameter.TitrPara.Direction +,
-, auto
Parameters for SET: Titration direction.
"auto" means the titration direction is determined automatically by the instru-
ment. If 2 EP's have been set in a SET titration, the titration direction is given
by the two EP's. The entry of the titration direction is then invalid.
3.2.2.31. Mode.Parameter.Presel.Cond ON, OFF
Mode.Parameter.Presel.DriftDisp ON, OFF
Parameters for SET:
.Cond: Conditioning ON/OFF
.DriftDisp: Drift display during conditioning ON/OFF.
3.2.2.32. Mode.Parameter.Measuring.SignalDrift
pH, U, Ipol, T:
0.5...999, OFF
Upol: 0.05...99.9, OFF
Mode.Parameter.Measuring.UnitSigDrift read
only
Mode.Parameter.Measuring.EquTime 0...9999, OFF
Parameters for MEAS: Criteria for the measured value acquisition. Measured
value drift in mV/min (with pH, U, Ipol), µA/min (with Upol), resp. °C/min
(with T). Equilibration time in s. OFF means that the corresponding criterion is
switched off. If both criteria are OFF, the measurement continues indefinitely.
If the equilibration time has never been edited, it is automatically calculated by
the instrument to match the drift, see page 45. After it has been edited once, it
remains in force with the set value.
3.2.2.33. Mode.Parameter.Measuring.MeasInput
1, 2, diff.
Mode.Parameter.Measuring.Ipol ±127...1...+127
Mode.Parameter.Measuring.Upol ±1270...400...+1270
Mode.Parameter.Measuring.PolElectrTest ON, OFF
Parameters for MEAS:
Selection of the measuring input; valid with measured quantities pH and U.
"diff." means differential amplifier, see page 155.
With Ipol, the inquiries for the polarization current in µA (Ipol) and
.PolElectrTest are valid.
With Upol the inquiry for the polarization voltage in mV (Upol) is valid. Entry in
steps on 10 mV.
Besides .PolElectrTest is valid.
If the test for polarized electrodes is switched on, it is performed on change-
over from the inactive state to the measurement.
3.2.2.34. Mode.Parameter.Measuring.Temp -170.0...25.0...500.0
Parameters for MEAS: Measurement temperature in °C. If a Pt100 or Pt1000
is connected, the temperature is measured.
The temperature is used for the temperature correction in pH measurements.
3.2.2.35. Mode.Parameter.Calibration.MeasInput
1, 2, diff.
Parameters for CAL: Selection of the measuring input. "diff." means differen-
tial amplifier, see page 155.
