Teledyne 4060 manual Alt-Span, Model Screen, System Self-Diagnostic Test

Series 4060 Operation

________________________________________________

Begin Span:

ENTER-YES ESCAPE-NO

________________________________________________

Pressing <Enter> enters the SPAN mode in the Sampling Phase. This is similar to the Analysis Mode both in the Sampling Phase and Analysis Phase. The difference is that, at the end, the analyzer calculates the calibration constants rather than the standard concentration calculation. After both Sampling Phase and Analysis Phase are complete, the calculation is performed and the 40660 re-enters Analysis Mode.

4.6.6 ALT-SPAN

If a particular compound of interest is not contained in the span gas, another compound existing in the span gas can be used for the alternate calibration.

4.6.7 The Model Screen

The MODEL screen displays the model, and software version information. It is accessed via the MAIN MENU by scrolling (UP/DOWN > to MODEL and pressing <Enter>.

4.6.8 System Self-Diagnostic Test

The Model 4060 has a built-in self-diagnostic testing routine. Preprogramming signals are sent through the power supply, output board, preamp board and sensor circuit. The return signal is analyzed, and at the end of the test the status of each function is displayed on the screen, either as GOOD or BAD. If any of the functions fail, the System Alarm is tripped.

Note: The self diagnostics are run automatically by the analyzer whenever the instrument is turned on, but the test can also be run by the operator at will.

Note: The self diagnostics will interrupt analysis temporarily.
