Any time there is a pneumatic configuration change, there is risk of impacting the
internal measure/reference pressure. To compensate for this, a backpressure
compensation calibration is required each time. Set the calibrator to generate ozone at
the flow rate intended for operation. While the instrument is generating ozone, go to the
SETUP>MORE>DIAG>818>...>BACKPRESSURE COMPENSATION menu and
press ENTR, shown in the following illustration, to initiate the calibration; the operation
will take a few minutes:
Make sure that the T700 is
generating ozone at the
intended operational flow rate.
