6.13.4. Analog I/O Configuration

The analog I/O functions that are available in the GFC 7000TA are:

	Table 6-16: DIAG - Analog I/O Functions
Sub Menu	Function
AOUTS CALIBRATED:	Shows the status of the analog output calibration (YES/NO) and initiates a calibration of all
	analog output channels.
CONC_OUT_1	Sets the basic electronic configuration of the A1 analog output (CO2). There are three options:
	Range: Selects the signal type (voltage or current loop) and full scale level of the output.
	REC_OFS: Allows setting a voltage offset (not available when RANGE is set to CURRent loop.
	Auto_CAL: Performs the same calibration as AOUT CALIBRATED, but on this one channel only.
	NOTE: Any change to RANGE or REC_OFS requires recalibration of this output.
CONC_OUT_2	Same as for CONC_OUT_1 but for analog channel 2 (CO2 )
TEST OUTPUT	Same as for CONC_OUT_1 but for analog channel 4 (TEST)
AIN CALIBRATED	Shows the calibration status (YES/NO) and initiates a calibration of the analog to digital
	converter circuit on the motherboard.
XIN1	For each of 8 external analog input channels, shows the gain, offset, engineering units, and
.	whether the channel is to show up as a Test function.
