Operating Instructions Model GFC7000TA Carbon Dioxide Analyzer
Teledyne Analytical Instruments 124
To configure the analyzer’s three 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 Section 6.13.4.1.
Calibrating the output channel. This can be done automatically or manually for each channel, see
Section 6.13.4.2 and 6.13.4.3.
Adding a bipolar recorder offset to the signal, if required (Section 6.13.4.2.)
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 6-17: 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.
