5.9.2. ANALOG OUTPUT
Analog Output is used as a step test to check the accuracy and proper operation of the
analog outputs. The test forces all four analog output channels to produce signals
ranging from 0% to 100% of the full scale range in 20% increments. This test is useful
to verify the operation of the data logging/recording devices attached to the analyzer.
(See also Section
12.5.8.2).
Access the Analog Output Step Test from the DIAG Menu as follows:
5.9.3. ANALOG I/O CONFIGURATION
The GFC7001T/GFC7001TM Analyzer comes equipped with four analog outputs.
•
The first two outputs (
A1 & A2)
carry analog signals that represent the
currently measured concentration of CO (see Section 5.4.1).
•
The third output (
A3
) is only active if the analyzer is equipped with one of
the optional 2
nd
gas sensors (e.g. O
2
or CO
2
).
•
The fourth output (
A4
) outputs a signal that can be set to represent the
current value of one of several test functions (see Table 5-9).
Table 5-5 lists the analog I/O functions that are available in the
GFC7001T/GFC7001TM Analyzer.
