5.9.2. ANALOG OUTPUT (DIAG AOUT)
Use Analog Output to verify functionality and accuracy of the analog outputs. The test
forces all 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.
Section 12.7.6.1 presents instructions for use in troubleshooting and service.
5.9.3. ANALOG I/O CONFIGURATION (DIAG AIO)
The T200 analyzer comes equipped with four analog outputs. The first three outputs
(
A1 A2, & A3) carry analog signals that represent the currently measured concentrating
of NO
x
, NO and NO
2
(see Section 5.4.2.1). 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).
The following table lists the analog I/O functions that are available in the T200 analyzer.

SECTION
AOUT CALIBRATED
Initiates a calibration of the
A1
,
A2
,
A3
and
A4
analog output channels that
determines the slope and offset inherent in the circuitry of each output.
These values are stored and applied to the output signals by the CPU
automatically.
5.9.3.1
CONC_OUT_1
Sets the basic electronic configuration of the
A1
output (NO
x
Concentration).
There are four options:

RANGE
1
: Selects the signal type (voltage or current loop) and level of the
output

REC OFS
: Allows them input of a DC offset to let the user manually adjust
the output level

AUTO CAL
: Enables / Disables the
AOUT CALIBRATION
Feature

CALIBRATED
: Performs the same calibration as
AOUT CALIBRATED
, but
on this one channel only.
