Calibration
redox absolute "Data entry 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.
CAB4 / CAB8 Temperature 1: 25.0 °C
07.00
(–2.00 ... +16.00pH)
Enter pH value of buffer 1 / 2
(only with manual buffer)

Checks the stability of the calibration
Wait until the pH measurement is stable:
Time does not count down,
pH value no longer flashes,
Display "Measured value stable"
Then press "E".

CAB6 / CAB10 Invalid calibration value Note in display:
If an error occurs, (e.g. incorrect buffer used), this
message is displayed.

Note in display:
Info on electrode.
Data on the zero point, slope and calibration quality.
–
CAB12 Electrode status K1 good Note in display:
Electrode status:
There are three status messages for the electrode
status: "good", "OK.", "bad". If the status is displayed
"bad", electrode replacement is recommended to
ensure the quality of the pH measurement.

CAB15 Accept
Reject
Recalibrate
End of calibration
Accept
: Pressing "E" accepts the new calibration data.
Reject
: The data is not accepted, a recalibration won’t
be started.
Recalibrate
: The data is rejected and a new calibration
will be started.
E1
CAB16 Electrode in medium? Note in display:
If the electrode is back in the medium, so that
measurement can take place?

CB Calibration with
abs. data entry Note in display
Display of the type of on-site calibration selected in the
calibration settings.

CBA1 0000 mV
(–1500 ... +1500 mV)
Entry of offset value
Enter the mV value for the electrode offset (electrode
offset = deviation of the measured value display from
buffer solution mV value)
Confirm by pressing "E". The entered value is effective
immediately.
The maximum offset is 400 mV.
E2
CBA3 Offset too high / too low Note in display:
Error message if the entered offset leaves the
maximum range.
