2.1.6 Output 0-1 VDC or RS232

Both the AD300 and MD300 provide signal outputs for use with
recorders and computers. The 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 2-9.
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 2-9. 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.
