Calibration Check

The Micro I is calibrated to read in litres at body temperature,
barometric pressure saturated with water vapour (BTPS).
The calibration should remain stable indefinitely, unless the
transducer is physically damaged, and the unit should not require re-
calibration. However, to ensure the correct functioning of the unit we
do recommend that a calibration check is performed after each
patient or when the transducer was removed for cleaning.
To perform a calibration check select calibration check option from the
setting menu and the display will show:
Connect a 3L syringe to the Micro I with the minimum of adapters and
inject the syringe volume into the transducer evenly, without pausing.
When complete the display will show:
The acceptable calibration accuracy is +/- 3.5%. If the calibration
accuracy is outside of this range then the tick will be replaced by a
cross. If this happens then check the syringe and the connections for
leaks and repeat the check. If the Micro I is repeatedly outside the
