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 to set 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.

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, see Sections 6.9.4.1.

Calibrating the output channel. This can be done automatically or manually for each channel, see
Sections 6.9.4.2 and 6.9.4.3.

Adding a bipolar recorder offset to the signal, if required (Section 6.9.4.4.)

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.
