To provide an indication of the range, a second pair of analog output
terminals are used. They generate a steady preset voltage (or current when
using the current outputs) to represent a particular range. Table 3-2 gives the
range ID output for each analysis range.

NOTE:
Impendance across 4-20mA output should not exceed 1000
ohms. Note polarity of terminals when wiring to the analog
outputs. Do not short 0-1VDC output for long period of time,
or damage may occur to analyzer.
CAUTION: Voltage may be present on alarm contacts when line power
is disconnected.
