Upol: 0.1...10 10...200.0, OFF
M Mode.P .Parameter.D .DosPara.UnitD .UnitDyn read only
M Mode.P .Parameter.D .DosPara.M .MaxRate 0.01...150, max. max.
M Mode.P .Parameter.D .DosPara.Mi .MinRate 0.01...5.0 5.0...9999
Parameters for DOC: Control parameters, see page 68.
.Dyn: Dynamics in pH, mV (with U and Ipol) or uA (with Upol). The corre-
sponding unit can be read with .UnitDyn.
.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. 3.2.2.60. 60. M Mode.P .Parameter.D .DosPara.Di .Direction +, -, auto auto
Parameters for DOC: Titration direction.
auto means the titration direction is determined automatically by the instrument.
The direction is used only when the ramp start is the same as init.
3.2.2. 3.2.2.61. 61. M Mode.P .Parameter.D .DosPara.St .StartV.T .Type abs., rel., OFF OFF
M Mode.P .Parameter.D .DosPara.St .StartV.V .V 00...999.99
M Mode.P .Parameter.D .DosPara.St .StartV.F .Factor 00... ± 999 999
M Mode.P .Parameter.D .DosPara.St .StartV.R .Rate 0.01...150, max. max.
M Mode.P .Parameter.D .DosPara.P .Pause 00...999 999
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
(Volume).
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. 3.2.2.62. 62. M Mode.P .Parameter.D .DosPara.Me .MeasInput 11, 2, diff.
M Mode.P .Parameter.D .DosPara.I.Ipol 0...11... ± 127
M Mode.P .Parameter.D .DosPara.Up .Upol 0...400 400... ± 1270
M Mode.P .Parameter.D .DosPara.Po .PolElectrTest ON, OFF OFF
Parameters for DOC:
Selection of the measurement input (MeasInput) applies to the measured quan-
tities pH and U. diff. means differential amplifier, see page 215.
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. 3.2.2.63. 63. M Mode.P .Parameter.M .Measuring.S .SignalDrift
pH, U, Ipol, T: 0.5...999, OFF OFF
Upol: 0.05...99.9, OFF OFF
