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
periodically.
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
