2. Immerse redox sensor in the test
container with redox buffer solution
(e.g. 465 mV)
3.
Start test with
ð
Test is running.
A buffer value is suggested
once the waiting time has
expired.
4. Adjust displayed value of "buffer"
(flashing) using , and to
the mV value of the redox buffer
solution in the test container and
confirm the value with
ð
The D1Cb displays the status
message of the redox sensor in
plain text. If the redox sensor is
functioning correctly, perma‐
nent display 1 will be displayed
directly
5. If the redox sensor is unclean or
defective, the redox sensor should
be cleaned, as described in the
redox sensor operating manual, or
alternatively replaced
Should the result of the calibration lie out‐
side of the specified error limits, an error
message will appear, see

sors. Description of the Error Messages ’
