(this helps to compare the slope values over the time when re-calibrating).
• Assure that the slope of a new sensor is 50...150 mg/nA, otherwise the sensor has a
malfunction. Press ^ ^ ^ ^ if the slope is okay.
i The signal converter now asks store value? store value? store value? store value?
• Using or choose yes yes yes yes to store the calibration values or no no no no to discard them.
