Fault Diagnosis With Dashboard Functions - Teledyne T200 User Manual

F
AULT
In addition to being useful as predictive diagnostic tools, the functions viewable in the
Dashboard can be used to isolate and identify many operational problems when combined
with a thorough understanding of the analyzer's principles of operation (see Section 6).
The acceptable ranges for these functions are listed in the "Nominal Range" column of the
analyzer Final Test and Validation Data Sheet shipped with the instrument. Values outside
these acceptable ranges indicate a failure of one or more of the analyzer's subsystems.
Functions whose values are still within acceptable ranges but have significantly changed
from the measurement recorded on the factory data sheet may also indicate a failure.
Make note of these values for reference in troubleshooting.

If no value displays for any of these Dashboard functions, it
indicates an OUT OF RANGE reading.
Sample Pressure measurements are represented in terms of
"Absolute Atmospheric Pressure" because this is the least
ambiguous method for reporting gas pressure.
Absolute atmospheric pressure is about 29.92 in-Hg-A at sea
level. It decreases about 1 in-Hg per 1000 ft gain in altitude. A
variety of factors such as air conditioning systems, passing
storms, and air temperature, can also cause changes in the
absolute atmospheric pressure.
