• Enter the laboratory value using or and press ^.
i The signal converter now matches the "stored value" to the laboratory value and makes a
re-calibration. The slope appears on the display and it is stored in the calibration logbook
(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?
• Using or choose yes to store the calibration values or no to discard them.
• Press ^ to confirm.
• Press ^ several times until the questions appears if the configuration should be stored.
