Calibration
redox relative

"Calibration relative"
For calibration, two tanks are filled with a sample of the medium. The contents of the first
tank are detoxified and are called Buffer 1.
The contents of the second tank are left unchanged and are called Buffer 2.

INFO
Selection for calibration
(only two-circuit)
Select electrode 1 or 2, and then run through calibra-
tion for each individual electrode.
Note in display
Display of the type of on-site calibration selected in the
calibration settings.
Handling instructions
Immerse the electrode in buffer 1 / 2 (detoxified
sample, see above).
Confirm by pressing
Enter buffer
Enter the relative redox value of buffer 1 / 2 (detoxified
sample) in percent.
Checks the stability of the calibration
225 Wait until the measurement is stable:
Time does not count down,
mV value no longer flashes,
Display "Measured value stable"
Confirm by pressing
Note in display:
Error message if the entered offset is too large.
F
End of calibration
Accept: Pressing
Reject: The data is not accepted and the device has
not been recalibrated.
Recalibrate: The data is rejected and the device is
recalibrated.
Note in display:
If the electrode is back in the medium, so that measure-
ment can take place?
