Calculating the Analog Voltage Output
The OxiMax N-600x pulse oximeter data port provides analog voltage outputs
between pins 6, 13, 14, and ground (pin 10), which can be used to calibrate
oximeters such as a chart recorder. The voltage represents a specific measured
parameter's current value. The voltage differential varies proportionally from 0.0 to
+1.0 VDC as the pin's parameter varies over its full range of values. For example, as
the current value of SpO
2
varies from 0 to 100%, the voltage from pin 6 to ground
(pin 10) varies from 0.0 to +1.0 VDC. A voltage of 0.94 volts indicates a current SpO
2
value of 94.
To set analog voltage output
1. Press the SETUP softkey.
2. Press the NEXT softkey three times.
3. Press the ANALOG softkey.
Figure 85. Analog Voltage Screen
a. VOLT Options —Selecting the 0 VOLT or 1 VOLT softkey causes that voltage to appear
at pins 6, 13, or 14 as referenced to ground pins 5 and 10.
b. STEP Option —Selecting the STEP softkey causes the voltage to increase from 0.0 to
1.0 volts at 1/10th-volt increments, with each step lasting at least one second.
4. Press the BACK softkey.
Have a qualified service technician perform the calibration of the attached device as
described in the
N-600x Service Manual .
