3 Move the syringe barrel in and raise the mercury to 200 mmHg (30 kPa). 200 mmHg is the
recommended calibration pressure.
4 In the Setup <Press Label> menu, select Cal. Press.
5 Select the calibration pressure from the list, for example 200 mmHg.
6 Select Confirm to recalculate the calibration factor using the applied pressure.
7 When the monitor displays <Press Label> mercury calibr. done at <Date and Time>, remove the
manometer tubing, syringe and extra stopcock. We recommend you replace the transducer dome
and tubing with sterile ones.
8 Label the transducer with the calibration factor shown in the Cal. Factor field in the pressure's
setup menu.
9 Reconnect the patient and start measuring again.
