RSS100 Product Specifications
Terminology
Absolute Maximum Ratings Defined
The Absolute Maximum Ratings are those
limits for the device that, if exceeded, will likely damage the device.
Exceeding the absolute maximum ratings voids any warranty and/or guarantee
from Korr Medical Technologies Inc.
Operating Characteristics Defined
The Operating Characteristics are those
limits for the device that, if exceeded, will cause the device to operate
out of specification. Under these conditions, values reported from the
device will be unreliable. After the "out-of-limit" condition
is corrected, the device will return to normal operation after either
an auto-zero or after the device has been powered down and then powered
back up.
Other Useful Terms
Common-mode Pressure - The
pressure applied to both ports of the differential pressure
transducer. Typically this is the breathing circuit airway pressure.
The differential pressure ports are connected to the "Flow Sensor"
pneumatic fittings on the RSS 100
front panel.
FSO - Full scale output.
Power Requirements
Absolute Maximum Ratings
- Input Voltage Range 90 to 264 VAC
- Input Frequency Range 50 to 60 Hz
Operating Characteristics
- Power Consumption 1 Watt (typ.) 3 watt (max.)
- Fuse Rating (110 VAC) 0.50 Amp Fast Acting
- Fuse Rating (220 VAC) 0.25 Amp Fast Acting
Environmental Conditions
Absolute Maximum Ratings
- Storage Temperature 0 to 70 ° C
Operating Characteristics
- Temperature 10 to 45 ° C
- Ambient Relative Humidity 0 to 95% (non-condensing)
- Barometric Pressure 400 to 900 mmHg
- Elevation -1000 to 16,000 Feet
- Vibration The RSS 100 uses sensitive differential
pressure transducers. These pressure transducers are sensitive to
vibration and mechanical shock. Excessive vibration will cause artifact
on both the flow and pressure signals. This may cause erroneous readings
on the monitor.

Linear Pneumotachs
Operating Characteristics
- Neonatal Flow Range ± 40 LPM
- Adult Flow Range ± 180 LPM
- Exercise Flow Range ± 1000 LPM
- Accuracy < 0.5% of reading typical in linear
range
NOTE: The linear pneumotachs are user supplied.
Korr does not dictate what types of linear pneumotachs can be used with
the RSS 100. The pneumotach selection
in the software accommodates display scaling. The accuracy and precision
of flow or volume calculations with a linear pneumotach will generally
be dependent on the characteristics of the pneumotach used. The RSS
100 will limit the accuracy and precision to about 0.5 % of reading
typical.
