Operating States
The HMIA has the following operating states: START-UP and RUN.
START-UP
When the System is powered on, illumination of the Green LED is indication that
power has been supplied to the HMIA. If there is no power to the HMIA the
Green LED is not lit and the hospital monitoring system, if attached to the HMIA,
should detect this as a probe disconnection or temperature probe error.
Once powered, the HMIA immediately establishes its link with the System and
performs a series of self tests including self-calibration – see below.
RUN
The HMIA is designed to provide a variable resistance value that is interpreted by
YSI-400 compliant hospital monitors as patient temperature. The patient
temperature is obtained via the T1 connection of the System.
Calibration
HMIA performs a self-calibration at START-UP. It will also perform a self-
calibration upon reconnection of the RS-232 port (for example, you might
temporarily disconnect the HMIA to allow access for data download). Self-
calibration takes less than half a second. During self-calibration, it may be
detected by the hospital monitor as a disconnected probe. At the end of self-
calibration the HMIA will automatically return to RUN.
Installation
The HMIA is quickly and easily installed.
Prior to installation of the HMIA, verify that the System has the correct software
to support the HMIA. The software version is displayed during initial start-up of
the System as per the figure below. The first number in the Software Version
must be equal to or greater than 1.04 (See Figure 4).
