Series 4060 Operation
Teledyne Analytical Instruments 51
________________________________________________
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.
