M Mode.P .Parameter.M .Measuring.E .EquTime 0...9999, OFF OFF
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 re-
mains in force with the set value.

M Mode.P .Parameter.M .Measuring.P .PolElectrTest ON, OFF OFF
Parameters for MEAS:
Selection of the measuring input; valid with measured quantities pH and U.
"diff." means differential amplifier, see page 215.
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 changeover
from the inactive state to the measurement.
3.2.2. 3.2.2.65. 65. M Mode.P .Parameter.M .Measuring.T .Temp -170.0...25.0 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. 3.2.2.66. 66. M Mode.P .Parameter.M .Measuring.TD .TDelta 1...22...999 999
Parameters for MEAS: Time interval in s for the acquisition of a measured value
into the measuring point list.
3.2.2. 3.2.2.67. 67. M Mode.P .Parameter.C .Calibration.M .MeasInput 11, 2, diff.
Parameters for CAL: Selection of the measuring input. "diff." means differential
amplifier, see page 215.
3.2.2. 3.2.2.68. 68. M Mode.P .Parameter.C .Calibration.C .CalTemp -20.0...25.0 25.0...120.0
Parameters for CAL: Calibration temperature in °C. If a Pt 100 or Pt1000 is
connected, the temperature is measured.

etc. up to 9 buffers
Parameters for CAL: pH of buffers. The first buffer which is set to "OFF" deter-
mines the number of buffers in the calibration.
