Introduction
The host system is responsible for the following:
• converting temperature measurement units from Kelvin to Fahrenheit and Celsius
• error message display
• providing display of last temperature
• meeting patient safety requirements
EMI/ESD Protection
Ferrite beads and 10-nF capacitors can be added to the assembly interconnect connections to
prevent malfunction of the assembly from electromagnetic interference. Locate these capacitors
near the interconnections to the SureTemp Plus board.
Mechanical Considerations
In general, do not place the SureTemp Plus module where it is subject to heat or electrical noise
generating devices.
The probe connector has a one-second debounce when going from no-probe to any other state,
and a zero second debounce when going to no-probe from any other state. Therefore, the host
must take this into consideration when waiting for the assembly to respond to a probe change.
The module must be located such that the probe tip is at or near ambient temperature. The host
is responsible for maintaining this requirement. A Programmable Ambient Bias is a feature
provided with the module software to help minimize the impact caused by any offset in probe tip
temperature versus ambient temperatures. Refer to Section 8, Serial Communication
Specification, for more detail.
Refer to the drawing below for detail concerning the probe cover box receptacle required to hold
the probe cover box.
