799 GPT Titrino
.MaxRate: Maximum allowed titration rate in ml/min. Max. means maximum
possible rate with the mounted Exchange Unit.
.MinRate: Minimum titration rate in ul/min.
3.2.2.60. Mode.Parameter.DosPara.Direction
Parameters for DOC: Titration direction.
auto means the titration direction is determined automatically by the instru-
ment. The direction is used only when the ramp start is the same as init.
3.2.2.61. Mode.Parameter.DosPara.StartV.Type
Mode.Parameter.DosPara.StartV.V
Mode.Parameter.DosPara.StartV.Factor
Mode.Parameter.DosPara.StartV.Rate
Mode.Parameter.DosPara.Pause
Parameters for DOC: Start volume and pause time in s. Runs after dispensing
of the start volume.
If an absolute start volume (abs.) has been selected, the volume is in ml (Vol-
ume).
A relative start volume (rel.) is dispensed as a function of the sample size:
Start volume in ml = sample size * factor (the factor selected (Factor)
The dosing rate in ml/min holds for both cases. Max. means the maximum
possible dosing rate with the Exchange Unit currently mounted.
3.2.2.62. Mode.Parameter.DosPara.MeasInput
Mode.Parameter.DosPara.Ipol
Mode.Parameter.DosPara.Upol
Mode.Parameter.DosPara.PolElectrTest
Parameters for DOC:
Selection of the measurement input (MeasInput) applies to the measured
quantities pH and U. diff. means differential amplifier, see page 216.
With Ipol, the requests for the polarization current in uA (Ipol) and
.PolElectrTest apply.
With Upol, the request for the polarization voltage in mV (Upol) applies. Entry
in steps of 10 mV. .PolElectrTest also applies.
If the test for polarized electrodes is switched on (ON), it will be performed on
the change from the inactive basic mode to an active mode.
3.2.2.63. Mode.Parameter.Measuring.SignalDrift
Mode.Parameter.Measuring.UnitSigDrift
Mode.Parameter.Measuring.EquTime
Parameters for MEAS: Criteria for the measured value acquisition. Measured
value drift in mV/min (with pH, U, Ipol, T), uA/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 69. After it has been edited once, it
remains in force with the set value.
