To configure the analyzer's four analog outputs, set the electronic signal type of each channel and
calibrate the outputs. This consists of:
1. 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 Section 2.2.1.1.
2. Calibrating the output channel. This can be done automatically or manually for
each channel, see Sections 2.2.1.2 and 2.2.1.3.
Adding a recorder offset to the signal, if required (Section 2.2.1.4.)
3.

Shows the status of the analog output calibration (YES/NO) and initiates a
calibration of all analog output channels.
Sets the basic electronic configuration of the A1 analog output. 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.
Same as for CONC_OUT_1 but for analog channel 2
Same as for CONC_OUT_1 but for analog channel 4 (TEST)
Shows the calibration status (YES/NO) and initiates a calibration of the analog to
digital converter circuit on the motherboard.
