Calibration
redox absolute
Endress+Hauser
"Calibration absolute"
The transmitter has a calibrated mV display range. One absolute mV value is set with
a single buffer solution (adaptation of the measuring chain offset). A buffer solution
preferably with 225 or 475 mV is used.

INFO
Selection for calibration
(only two-circuit)
Select electrode 1 or 2, and then run through
calibration 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 the buffer.
Confirm by pressing
Enter buffer
During calibration, enter the buffer mV value.
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.
0005
Note in display:
mV Info on electrode 1.
Data on the offset and calibration quality.
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?
