3.9.3 Editing sensor data
Open the dialog Sensors/Edit by either configuring a new sensor
(see Section 3.9.1) or selecting an existing sensor from the list and
modifying it with[Edit].
Enter an unambiguous name for the sensor under Sensor. For ISE
electrodes the ion whose concentration can be determined with the
sensor is also shown.
The Order number and Serial number are read out automatically
in case of intelligent sensors. The data can be entered manually for
non-intelligent sensors.
You can enter a Comment for each sensor.
3.9.4 Calibration data (for pH and ISE electrodes only)
Detailed information about calibrations is given under Edit
sensor/Calibration data. For pH electrodes the Slope is given in %
and the electrode zero point pH(0) is shown. For ISE electrodes the
Slope is given in mV; the electrode zero point E(0), the blank
concentration c(blank) and the variance are also shown. The variance
is only calculated, if the calibration has been carried out with at least
four standards. The calibration date is entered automatically after a
calibration has been carried out (see Section 4.7).
Under Calibration temperature the temperature at which the
calibration was carried out is shown. If the temperature was measured
and entered manually during the calibration then this is indicated by
manual. If the temperature was measured with a connected
temperature sensor then the type of sensor (Pt1000 or NTC) will be
shown. The Calibration date is entered automatically together with
the time. When a sensor is entered into the list for the first time the date
of entry will be given as the calibration date.
Under Calibration method the method used to calibrate the sensor is
shown. If the calibration data has been entered manually then manual
will be shown here. The user who carried out the calibration or entered
the calibration data manually is shown under User.
