5.0 OPERATION
Operation of the OxyTrans is very simple. Open the shut-off valves on the
upstream and downstream sides of the sensor. For most models, there are no
switches or other controls. The operator simply has to be sure that the gas flow
rate is within the specified range (1 to 2 SCFH, or 0.5 to 1 L/min.), and that new
readings have completely equilibrated before data is taken.
5.1 DIGITAL DISPLAY
The Digital Display shows you the current oxygen value. A bar graph at the top
symbolizes the analog output signal. See Figure 5-1.

5.2 ANALOG OUTPUT
The 4 to 20 mA electrical output will follow the changes in value of the measured
Oxygen, just as the digital display does. It may be remotely measured with a
series DC milliammeter, or used to drive a process controller or data acquisition
system.
