10.2.3 Setting Upper and Lower Limit Values on Graph
Set upper- and lower-limit values on the graph in the following procedure:
Press “Upper limit” in the Trend graph display. The numeric-data entry key appears.
Enter the upper-limit value. Also enter the lower-limit value in the same way. The allowable
settings for both upper-limit and lower-limit values range from 0 to 100 vol%O

(0 to 100 %H

for humidity, 0 to 1 kg/kg for mixing ratio.)
10.2.4 Default Setting
When the analyzer is delivered, or if data are initialized, the set data are by default, as shown in
Table 10.3.

NOTE
If a rapid change in the measured value occurs during sampling, no sampled data are plotted on
the graph. Use the graph indication tentatively. Check the output current for accurate data.
