3.2.2.64. 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 216.
With Ipol, the inquiries for the polarization current in uA (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.
3.2.2.65. 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.
3.2.2.66. Mode.Parameter.Measuring.TDelta 1...2...999 999
Parameters for MEAS: Time interval in s for the acquisition of a measured
value into the measuring point list.
3.2.2.67. Mode.Parameter.Calibration.MeasInput 1, 2, diff.
Parameters for CAL: Selection of the measuring input. "diff." means differen-
tial amplifier, see page 215.
3.2.2.68. Mode.Parameter.Calibration.CalTemp -20.0...25.0...120.0
Parameters for CAL: Calibration temperature in °C. If a Pt 100 or Pt1000 is
connected, the temperature is measured.
3.2.2.69. Mode.Parameter.Calibration.Buffer.1.Value 0...7.00...±20.00
Mode.Parameter.Calibration.Buffer.2.Value 0...4.00...±20.00, OFF
etc. up to 9 buffers
Parameters for CAL: pH of buffers. The first buffer which is set to "OFF" de-
termines the number of buffers in the calibration.
3.2.2.70. Mode.Parameter.Calibration.SignalDrift 0.5...2...999, OFF
Mode.Parameter.Calibration.EquTime 0...110...9999, OFF
Parameters for CAL: Criteria for measured value acquisition. Measured value
drift in mV/min, equilibration time in s. OFF means that the corresponding cri-
terion is switched off. If both criterions are on OFF, the measured value is ac-
quired immediately.
If the equilibration time has never been edited, it is automatically calculated by
the instrument to match the drift, see page 20. After it has been edited once, it
remains in force with the set value.
