Configuring the device
Consider the following options and settings before starting a
measurement:
•
Height Correction Unit nulling (if connected).
•
Using the analog I/O unit (if provided).
•
Using on-line PC monitoring and recording with BeatScope® Easy.
5.1
Height Correction Unit nulling procedure
The Height Correction Unit nulling should always be checked before
starting a measurement. If necessary a Height Correction Unit nulling
procedure needs to be performed. During a Height Correction Unit
nulling procedure the offset of the Height Correction Unit is determined
when the Height Correction Unit transducer and the reference point
(Figure 5.1 Checking the Height Correction Unit nulling) are at the same
level. This offset is stored in volatile memory and will therefore be no
longer available when Finometer® Model-2 is powered off. The same
holds true when the Height Correction Unit is disconnected and later
reconnected.
Check the Height Correction Unit before use on the presence of an air
column near the circular housing at the end of the tube. The presence
of a small air bubble ( < 0.5 cm ) is no problem.
The presence of a large air bubble ( > 0.5 cm ) points towards a
possible leakage of the fluid from the closed Height Correction Unit as
may be visible from remnants of the liquid, most likely on the circular
housing.
Don't use the Height Correction Unit if this is the case, but contact
Finapres Medical Systems B.V. , for replacement or repair of the Height
Correction Unit (see page 9).
