Calibration
redox relative "Data entry relative"
Entry of two % calibration points to which one mV value is assigned.
Calibration
redox relative "Calibration relative"
For calibration, two vessels are filled with a sample of the medium. The contents of the first vessel
are detoxified and used as buffer 1.
The contents of the second vessel are left unchanged and used as buffer 2.

In this field, create two measured value pairs (pair 1 and pair 2).
Measured value pair 1 in the range 0...30%: assign, for example, the voltage
0600 mV to the percentage value 20 %.
Measured value pair 2 in the range 70...100%: assign, for example, the voltage
–0600 mV to the percentage value 80 %.
The settings made become effective immediately after confirmation with

.
Offset too high / too low Note in display:
Error message if the entered offset leaves the maximum range.

End of calibration
Accept : Pressing
F
accepts the new calibration data.
Cancel : The data are not accepted, the calibration is not repeated.
Repeat calibration : The data are rejected and a new calibration is started.
Electrode submersed? Note in display:
Is the electrode back in the medium, so that measurement can take place?
