8 Finometer® Model-2
•
Explosion hazard exists when operated in the presence of
flammable gases and liquids.
•
Protection against the ingress of liquids is limited. Do not apply
electrical power to the device when liquids did enter, as this may
cause internal short circuits and unpredictable external electrical
currents.
•
Always use a grounded 3-wire electrical cable and connector to plug
into the power line.
•
Selecting a proper sized cuff and the correct placement of a cuff on
a finger are critical for success.
•
Do not wrap finger cuffs around a toe or the wrist of an infant.
•
Accuracy of measurement on a toe has not been established. An
inflated finger cuff applied to the wrist causes congestion of blood
in the distal circulation of the hand, which may become painful and
restricts distal oxygenation.
•
The zero adjustment of all pressure transducers built-in is
automatic, except for the pressure transducer of the Height
Correction Unit for which nulling has to be performed manually (see
section 5.1). It is the responsibility of the operator to periodically
check the zeros and sensitivities of the transducers. Finometer®
Model-2 devices leave our premises with carefully calibrated
transducers. Immediately after transport, and at any time that the
instrument is dropped or otherwise damaged, the zeros and
calibrations should be rechecked. These checks are quick and easy
to perform (see section 8.4).
•
For safe and reliable operation and optimal accuracy only use
Finapres Medical Systems B.V. cuffs and only use software
approved by Finapres Medical Systems B.V.
•
Externally generated analog signals coming from other devices,
such as respiratory signal and ECG can be connected to the
Finometer® Model-2 for recording. Furthermore, personal
computing equipment can be interfaced to the digital I/O port of
the Finometer® Model-2 for obtaining signals and data, and for
remote control. Connected equipment has to meet the IEC
specifications (IEC 601 for electro medical devices or IEC 950 for
data processing devices). The configuration has to meet the IEC
system standard (IEC 601-1-1). He who connects such additional
devices is responsible for adherence to the IEC 601-1-1 standard.

Complete specifications of Finometer® Model-2 are listed in
Chapter 9, Specifications.
