Analog Output
The Radical-7 Pulse CO-Oximeter can interface with various analog recording instruments or
strip chart recorders through its Analog Output connector located on the back of the
Docking Station. The output signals vary from approximately 0 to 1 volt in a linear fashion.
The actual analog output voltage generated may not exactly range between 0.0V to 1.0V. A
variance of ± 40 mV is acceptable.
Calibration
For instrument calibration purposes, the analog output signals can be set to either 0 Volts
or 1 Volt. Calibrate your analog recording system to those levels before use.
Nurse Call
The Nurse Call feature is available when the Radical-7 is operating as a standalone. Nurse
Call is based on the relay closing or opening depending on alarm, Low Signal IQ events, or
both. For maximum flexibility, either normally open (pin 6) or normally closed (pin 7)
signals are available. Only qualified personnel should connect one of these two signals and
common (pin 12) to a hospital’s Nurse Call system. During an alarm condition or a Low
Signal IQ event, depending on the configuration, the normally open pin will be connected to
the common pin and the normally closed will be disconnected. The Nurse Call polarity can
be inverted to accommodate various Nurse Call station requirements.
