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 output voltage of the A1 analog output (NO
X
) .
Range: Selects the signal type (voltage or current loop) and full scale value
of the output.
REC_OFS: Sets 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: Changes to RANGE or REC_OFS require recalibration of this output.
CONC_OUT_2 Same as for CONC_OUT_1 but for analog channel 2 (NO)
CONC_OUT_3 Same as for CONC_OUT_1 but for analog channel 3 (NO
2
)
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.
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.
Calibrating the output channel. This can be done automatically or manually for each
channel, see Sections 6.7.4 through 6.7.8.
Adding a bipolar recorder offset to the signal, if required (Section 6.7.5).
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 0-8: 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.
