All three outputs can be configured either at the factory or by the user for full
scale outputs of 0.1 VDC, 1VDC, 5VDC or 10VDC. Additionally A1 and A2
may be equipped with optional 0-20 mADC current loop drivers and configured
for any current output within that range (e.g. 0-20, 2-20, 4-20, etc.). The user
may also adjust the signal level and scaling of the actual output voltage or current
to match the input requirements of the recorder or data logger (See Section
4.13.4).
The A1 and A2 channels output a signal that is
proportional to the CO
2
concentration of the sample gas. Several modes are available which allow them
to operate independently or be slaved together. The user may also select between
a variety of reporting range spans (see Section 4.8).
EXAMPLE:
A1 OUTPUT: Output Signal = 0-5 VDC representing 0-1000 ppm concentration
values
A2 OUTPUT: Output Signal = 0 – 10 VDC representing 0-500 ppm concentration
values.
Output A3 is only active if the O
2
sensor option is installed. In this case a signal
representing the currently measured O
2
concentration is output on this channel.
The output, labeled A4 is special. It can be set by the user (See Section 4.13.9) to
output several of the test functions acce
ssible through the <TST TST> buttons of
the units sample display.
