average value
calculation:
The result of O

correction or instan-
taneous O
2
value can be output as an
average value over the preset period of
time.
Moving average method is used. Sampling
interval is 30 secs.
(Output is updated every 30 seconds.
Update is the averaged value of the most
recently elapsed averaging time period.)

to 59 minutes (in increments of 1 minute)
or 1 to 4 hours (in increments of 1 hour).
Average value resetting:
The above-mentioned output of average
value is started from the initial state by
opening the average value resetting input
terminals after short circuiting for 1.5 sec
or longer.
Output is reset by input voltage and
restarted by opening the terminal circuit.

Response interval may be changed de-

Interference from other gases:
Sample switching design effectively
minimizes interference. But it may occur
depending on component gas and its
concentration.
