4.6.3. ANALOG I/O CONFIGURATION
Table 4-8 lists the analog I/O functions that are available in the T101.

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 (H
2
S). 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 (H
2
S)
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.

XIN8
For each of 8 external analog inputs channels, shows the gain, offset, engineering
units, and whether the channel is to show up as a Test function.
To configure the analyzer’s four analog outputs, set the electronic signal type of each
channel and calibrate the outputs. This consists of:
Selecting an output type (voltage or current, if an optional current output driver has
been installed) and the signal level that matches the input requirements of the
recording device attached to the channel (Section 4.6.3.1).
Calib
rating the output channel. This can be done automatically or manually for each
channel (Sections 4.6.3.2 and 4.6.3.3).
Adding a bip
olar recorder offset to the signal, if required (Section 4.6.3.4)
In its standard configuration, the analyzer’s outputs can be set for the following DC
voltages. Each range is usable from -5% to + 5% of the nominal range.
Table 4-10. Analog Output Voltage Ranges
RANGE MINIMUM OUTPUT MAXIMUM OUTPUT
0-0.1 V -5 mV +105 mV
0-1 V -0.05 V +1.05 V
0-5 V -0.25 V +5.25 V
0-10 V -0.5 V +10.5 V
The default offset for all ranges is 0 VDC.
