5.9.2. ANALOG OUTPUT (DIAG AOUT)

Analog Output is used 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 9110T analyzer comes equipped with four analog outputs. The first three outputs (A1 A2, & A3) carry analog signals that represent the currently measured concentrating of NOx, NO and NO2 (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 9110T analyzer.

SUB MENU		FUNCTION	MANUAL
			SECTION
	Initiates a calibration of the A1, A2, A3 and A4 analog output channels that
AOUT CALIBRATED	determines the slope and offset inherent in the circuitry of each output.		5.9.3.1
	These values are stored and applied to the output signals by the CPU
	automatically.
	Sets the basic electronic configuration of the A1 output (NOx Concentration).
	There are four options:
	∙	RANGE1: Selects the signal type (voltage or current loop) and level of the
CONC_OUT_1		output
	∙	REC OFS: Allows them input of a DC offset to let the user manually adjust
		the output level	5.9.2
	∙	AUTO CAL: Enables / Disables the AOUT CALIBRATION Feature
	∙	CALIBRATED: Performs the same calibration as AOUT CALIBRATED, but
		on this one channel only.
CONC_OUT_2	∙	Same as for CONC_OUT_1 but for analog channel A2 (NO Concentration)
CONC_OUT_3	∙	Same as for CONC_OUT_1 but for analog channel A3 (NO2 Concentration)
TEST OUTPUT	∙	Same as for CONC_OUT_1 but for analog channel A4 (TEST CHANNEL)	5.9.4
AIN CALIBRATED	Initiates a calibration of the A-to-D Converter circuit located on the Motherboard.		5.9.3.10
