The signal output for concentration is linear over the currently se-
lected analysis range. For example, if the analyzer is set on a range that
was defined as 0–10 % hydrogen, then the output would be as shown in
Table 3-2.

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

The nine alarm-circuit connector pins connect to the internal alarm
relay contacts. Each set of three pins provides one set of Form C relay
contacts. Each relay has both normally open and normally closed contact
connections. The contact connections are shown in Table 3-4. They are
