3.6.1 Analog Output
The standard model IR7000 is equipped with a single set of analog
output terminals accessible from the rear panel. The output is set at the
factory to 0–1 VDC but can be changed to 0–5V or 0–10V full scale by
moving the slides on the switch labeled “S1” on the I/O board. The switch
is located at the upper edge of the I/O board as shown in Figure 3-6. Use
the table in the figure to set the slides for the desired output voltage. A 4–
20 mA isolated or non-isolated output is also available as an option.
A second set of 0–1, 0-5, or 0-10 VDC output terminals may be
driven if the optional O

monitoring channel is installed. If the instrument
is equipped with a dual bench, there will be 2 sets of terminals, one for
each bench.
