Teledyne 100E - Figure 11-2: Example of Signal I;O Function

• The technician can view the raw, unprocessed signal level of the analyzer’s critical
inputs and outputs.
• All of the components and functions that are normally under instrument control
can be manually changed.
• Analog and digital output signals can be manually controlled.
This allows to systematically observe the effect of these functions on the operation of the
analyzer. Figure 11-2 shows an example of how to use the signal I/O menu to view the
raw voltage of an input signal or to control the state of an output voltage or control
signal. The specific parameter will vary depending on the situation. Please note that the
analyzer will freeze it’s concentration output while in the diagnostic signal I/O menu.
This is because manually changing I/O outputs can invalidate the instrument reading.
