Portable Oxygen Analyzer Operation
Teledyne Analytical Instruments 21
2.1.5 Output 0-1 VDC or RS232
The AX300-I Portable Oxygen Analyzer provides signal outputs
for use with recorders and computers. These instruments are supplied
standard with a 0-1 VDC output. An optional 0-1 VDC Interface Cable
(P/N B-75554) is available from Teledyne for this purpose.
To connect the analyzer to an analog recording device:
1. Insert one end of the interface cable into the output port on
the side of the instrument. See Figure 2-8.
2. Insert the other end into the analog recorder device. Make
sure the device is equipped to handle a 0-1 VDC signal.
When properly calibrated, the output signal generated by the
analyzer is linear and proportional to the oxygen concentration.
If you requested Option-B (RS 232 digital output) at the time of
purchase, a digital RS 232 signal is output from the output port shown in
Figure 2-8. Use the optional RS 232 Interface Cable (P/N B-75555)
available from Teledyne for connection to a standard RS 232 port on a
computer or other suitably equipped digital device.

If your instrument is set for analog (0-1 VDC) output, you can
reconfigure it to use the digital output by changing a jumper on the
internal PC board.
To activate the digital output:
