Save Calibration Yes
As soon as the drift conditions have been fulfilled (or [ENTER] was pressed in manu-
al mode) the display changes to show the slope calibration factor S and the offset
calibration factor Z. Select Yes to save the calibration values and the successful
Calibration is confirmed on the display.
Select Process Calibration by pressing the
key. To show the ongoing Calibration Process an "H"is displayed in the top left hand
corner.
The "H" changes to "A" (or channel "B" for multi-channel devices) if Process Calibra-
tion is selected to show the user the ongoing calibration on Channel "A".
Take a sample and press the [ENTER] key again to store the current measuring Value.
After determining the pH Value of the Sample press the
the calibration. If the display prompts you to enter the calibration security code, press
the or key to set the calibration security code, then press the ENTER key to con-
firm the calibration security code.
Enter the pH value of the sample then press the [ENTER] key to start calibration.
After the calibration the slope calibration factor S and the offset calibration factor Z are
displayed. Select Yes to save the new calibration values and the successful Calibra-
tion is confirmed on the display. The "A" in the top left hand corner disappears.
