7.8.2.1 Auto Mode
Place the electrode in the first buffer solution and press the [ENTER] key to start the calibration.
The display shows the buffer the transmitter has recognized (Point 1) and the measured value.
As soon as the stabilisation criteria have been fulfilled, the display changes and prompts you to
place the electrode in the second buffer.
Place the electrode in the second buffer solution and press the [ENTER] key to go on with the
calibration.
The display shows the second buffer the transmitter has recognized (Point 2) and the measured
value.
As soon as the stabilisation criteria have been fulfilled, the display changes to show the slope
calibration factor S and the offset calibration factor Z.
After a successful calibration, the calibration values are taken over (Adjust) or were aborted
(Calibrate or Abort).
If ”Adjust” or ”Calibrate” are chosen, the message ”Calibration successful” is displayed. In any
case you will get the message ”Re-install sensor” and ”Press ENTER” on the display. After press-
ing ”ENTER” the M400 returns to the measuring mode.
7.8.2.2 Manual Mode
Place the electrode in the first buffer solution. The display shows the buffer the transmitter has
recognized (Point 1) and the measured value. Press [ENTER] to proceed.
Place the electrode in the second buffer solution. The display shows the buffer the transmitter
has recognized (Point 2) and the measured value. Press [ENTER] to proceed.
