OZONE ANALYZER BMT 964 Manual, Rev. 04/2021
13
Zeroing the Instrument from the Front Panel
If ozone concentration is shown on the display and the ZERO button is pushed, the instrument
displays the question:
Zeroing: Are you sure?
Due to the fact that zeroing with ozone would lead to wrong measurement results, this question
gives the user the opportunity to stop. This can be done by pressing the button BACK. In case
there is really no ozone present in the cuvette, the ZERO button may be pressed again, after
which zeroing starts. Further information about zeroing the BMT 964 can be found on page 23.
